OPINION
The government seeks relief, by way of this interlocutory appeal, from the Memorandum Opinion and Order entered in the District of Maryland on August 4, 2006, suppressing evidence seized by federal officers from the residence and medical offices of Dr. Pradeep Srivastava pursuant to search warrants issued by a magistrate judge.
See United States v. Srivastava,
I.
A.
In early 2003, a criminal investigation was initiated by the Department of Health and Human Services (the “HHS”), the Federal Bureau of Investigation (the “FBI”), and the government’s Office of Personnel Management, into an alleged health care fraud scheme involving Srivastava, a licensed cardiologist practicing with two associates in Maryland. The federal authorities suspected that Srivastava and his associates were involved in the submission of false claims to various health care benefit programs, in violation of 18 U.S.C. § 1347. 1 As a result, the authorities commenced an investigation into Srivastava’s billing practices.
In March 2003, the fraud investigation had progressed to the stage where Jason Marrero, an HHS agent specializing in the investigation of health care fraud (“Agent Marrero”), applied to a magistrate judge in the District of Maryland for three search warrants. By Agent Marrero’s submission to the judge, the government sought the seizure of the “fruits, evidence and instrumentalities of false claims submissions” from Srivastava’s medical offices in Greenbelt and Oxon Hill (the “Greenbelt office” and the “Oxon Hill office,” respectively), and from his residence in Potomac (the “Potomac residence”). J.A. 31.
2
The applications for the search warrants were supported by Agent Marrero’s nineteen-page affidavit (the “Affidavit”), in
Significantly, the Affidavit made factual assertions indicating that documents and records related to Srivastava’s medical practice — constituting possible evidence of health care fraud — would be found in the Potomac residence:
• A former employee of Srivastava, who was a confidential informant in the fraud investigation, confirmed that Srivastava “directed most of the billing to health care benefit programs,” and that such programs “sent most payments and Explanation of Benefit letters to Srivastava’s house,” J.A. 42;
• Srivastava had the medical practice’s “insurance billing done from [his] house,” and the practice submitted such billing to insurers both “by mail and electronically by computer,” id.; and
• Srivastava had “listed and currently lists [the Potomac] residence ... as the billing address for claims submitted electronically to Medicare,” id. at 46.
On the basis of these and other facts spelled out in the Affidavit, Agent Marrero asserted “that there is probable cause to believe that Srivastava’s [Greenbelt and Oxon Hill] offices ... and Srivastava’s [Potomac] residence ... contain fruits, evidence and instrumentalities of [health care fraud] and that the items [sought] are fruits, evidence and instrumentalities of the violation.” Id. at 48.
On March 20, 2003, the magistrate judge issued three search warrants, each accompanied by an identical two-page “Attachment A,” captioned “Items To Be Seized Pursuant To A Search Warrant.” J.A. 49-51. 3 The warrants “commanded” the searching officers, inter alia, to search the Greenbelt office, the Oxon Hill office, and the Potomac residence on or before March 27, 2003, and, if the property listed in Attachment A “be found there to seize same.” Id. at 49. Attachment A introduced the list of documents and records to be seized under each warrant as follows:
The following records including, but not limited to, financial, business, patient, insurance and other records related to the business of Dr. Pradeep Srivastava [and his two associates], for the period January 1, 1998 to Present, which may constitute evidence of violations of Title 18, United States Code, Section 1347.
Id.
at 50. Attachment A then specified in some detail ten categories of things that were to be seized, including personnel records; health care benefit program manuals and documentation; correspondence between medical office personnel and health care benefits program personnel; documents relating to investigations of the medical group’s billing practices; records of complaints about patient treatment; records of certain specified patients; computer files or programs related to the other materials identified; plus calendars, appointment books, correspondence, passports, photographs, and other documents indicating Srivastava’s where
B.
On March 21, 2003, HHS and FBI agents simultaneously executed the search warrants at the three specified locations. Prior to the searches being conducted, Agent Marrero briefed the executing officers on what was to be done, summarizing for them the contents of the warrants and the Affidavit. Two of the searches — those conducted at the Greenbelt office and the Potomac residence — yielded the seizure of documents and records that are specifically implicated in this appeal. 5
From the Potomac residence, the officers seized, inter alia, copies of the tax
In April 2003, after the searches had been completed, the government returned to Srivastava approximately 80% of the documents and records seized from the Potomac residence. 6 During the same time frame, Agent Marrero provided the United States Attorney with a copy of the Bank of India Transfers, which were also provided to the Internal Revenue Service (the “IRS”). IRS agents thereafter concluded that the Bank of India Transfers indicated a likely failure to disclose a foreign financial account. 7 After obtaining other information relating to the Transfers — for example, that Srivastava had not acknowledged any foreign bank accounts on his 1999, 2000, and 2001 personal income tax returns — the IRS initiated an investigation of Srivastava for possible reporting violations. This investigation ultimately led to his indictment for tax fraud.
C.
On October 12, 2005, Srivastava was indicted by a grand jury in the District of Maryland on two counts of tax evasion, in violation of 26 U.S.C. § 7201, plus one count of making false statements on a tax return, in violation of 26 U.S.C. § 7206(1). 8 According to the indictment, Srivastava had concealed more than $40 million in capital gains on investments in technology stocks and stock options, and underpaid his income taxes for tax years 1998 and 1999 by more than $16 million. The indictment alleges, inter alia, that:
• Srivastava invested a substantial portion of income from his medical practice in stocks and stock options, but failed to provide important information relating to his stock and stock options trading to the accountant who prepared his tax returns;
• As a consequence of those omissions, the accountant prepared, and Srivastava filed, tax returns that resulted in an underpayment of taxes in 1998 by approximately $165,000, and in 1999 by more than $16 million;
• In 2000, Srivastava’s portfolio substantially declined in value, and he failed to disclose short-term capital losses of approximately $ 10.8 million. Although nondisclosure of these losses did not affect his taxes due and owing for 2000, it served to conceal his unreported short-term capital gains for 1998 and 1999.
In January 2006, following his indictment, Srivastava filed a suppression motion challenging the constitutionality of the seizures that had been made nearly three years earlier, pursuant to the search warrants. In that motion, Srivastava contended, inter alia, that documents and records seized in the searches were of a personal nature and not subject to seizure, and that the seized documents and records exceeded the scope of the warrants. 9 Responding to the suppression motion, the government advised the court that it possessed approximately twenty-five documents and records — all seized from the Potomac residence — that it intended to use as trial evidence (collectively, the “Potomac Documents”). Several of the Potomac Documents had been seized from Srivastava’s bedroom in the Potomac residence, including:
• An IRS Form 1099 for tax year 1999 found in an envelope marked as “1999 Final”; 10
• Several documents from an envelope dated October 15, 1996, including multiple IRS Forms 1099 for tax year 1998, a handwritten document describing “Bank Interest Payment,” and a statement and fax relating to accounts with “Mesirow Financial Inc./Bentley~ Lawrence Securities”; 11 and
• Several documents from a folder labeled “1996 Tax Info.,” including IRS Forms 1099 for tax years 1997 and 1999, spreadsheets for accounts variously labeled “Options Transactions” and “Stock Transactions,” a “Schedule of Realized Gains and Losses” dated October 14, 1999, and a 1999 “Tax Reporting Statement.” 12
Several other Potomac Documents that the prosecution seeks to utilize at trial were found in a shoe box marked “Tax Return Info 2000,” seized from an office on the
• A fax (dated October 8, 2001) from Srivastava’s accountant requesting items needed to complete Srivastava’s 2000 tax return;
• A spreadsheet labeled “Accounts of Dr. Pradeep Srivastava/Stock Transactions — 8/25/99 to 12/31/99 By Bentley Lawrence Account”; and
• A handwritten document with information about various bank accounts and transactions.
In opposing the suppression motion, the government alternatively advised that, if the court suppressed the Potomac Documents, it intended to utilize at trial the Bank of India Transfers seized from the Greenbelt office, “to explain the independent source for [the IRS case agent’s] investigation and the inevitable discovery of the brokerage, bank and other evidence supporting the tax charges.” J.A. 110. The Bank of India Transfers included the following:
• A letter from Srivastava, dated December 16, 1999, printed on the medical practice letterhead of “Pradeep Srivastava, M.D., F.A.C.C.” and an associate, and faxed by the Greenbelt office manager to the State Bank of India in New York, directing a wire transfer of the sum of $150,000 for deposit in Srivastava’s account with the State Bank of India in New Delhi;
• A fax cover and confirmation sheet dated December 16, 1999, also on the medical practice letterhead; and
• Remittance confirmations of various dates from the State Bank of India regarding the $150,000 deposit and seven other deposits totalling more than $4 million.
On June 9, 2006, the court conducted an evidentiary hearing on Srivastava’s contentions regarding the scope of the search warrants and the constitutionality of their execution. At the hearing, the court heard testimony from Agent Marrero and an IRS agent, as well as argument concerning whether the seized documents and records were within the scope of the warrants. Srivastava contended, inter alia, that although such documents and records may have financial significance, they did not relate to his medical practice, were not evidence of health care fraud, and thus were not within the ambit of the warrants. The government maintained to the contrary, arguing that the seized documents and records plainly fell within the scope of the warrants and that the suppression motion should be denied.
D.
On August 4, 2006, the district court issued its Suppression Ruling, ordering the suppression of the Potomac Documents, the Bank of India Transfers, and all other evidence seized in the three searches. In so ruling, the court first determined that “in order to fall within the scope of the warrant, a financial record not only had to have some relationship to Dr. Srivastava’s business, but it also was subject to the requirement that it may constitute evidence that health care fraud had been committed.”
United States v. Srivastava,
Finally, the court considered the question of whether a blanket suppression of all of the seized evidence was warranted, concluding that
[e]ven if ... some of the documents at issue here were within the scope of the warrant, these documents would be excluded as well because the conduct of the agents who executed this warrant was so inappropriate as to warrant the exclusion of all evidence seized on March 21, 2003.

The government thereafter sought reconsideration of the Suppression Ruling, which the district court denied on March 12, 2007.

Legal determinations made by a district court with respect to a suppression issue, including interpretations of the scope of a search warrant, are reviewed de novo on appeal.

See United States v. Borromeo,
B.
This appeal obligates us to assess, in a pretrial context, the Suppression Ruling made by the district court in connection with the tax fraud prosecution pending against Srivastava. The appeal implicates questions related to the warranted searches of Srivastava’s Potomac residence and Greenbelt office. Such questions arise under the Fourth Amendment, which protects individuals against unreasonable searches and seizures conducted by the authorities, specifying its guarantee in the following terms:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
U.S. Const, amend. IV.
The review of Fourth Amendment search and seizure issues in our Court is
Our Court — as well as the Supreme Court and other judicial bodies — has consistently encouraged the authorities to act prudently in the Fourth Amendment context, and, when the circumstances permit, to seek and secure the authorization of a judicial officer — in the form of a warrant-before conducting a search or seizure.
See Ventresca,
By its Suppression Ruling, the district court determined that the search warrants authorized the seizure of only those “documents that related to Dr. Srivastava’s business
and
that may show in some way that health care fraud had been committed.”
United States v. Srivastava,
III.
In disposing of this appeal, we first assess whether the scope of the search warrants includes the two groups of documents that the government intends to use at trial: (1) the Potomac Documents and (2) the Bank of India Transfers. We then analyze whether the court’s blanket suppression of all the seized evidence was legally justified.
We begin our analysis with the government’s contention that the district court misconstrued the scope of the search warrant for the Potomac residence. In this regard, the court determined that the Affidavit demonstrated probable cause that documents and records relating to Srivastava’s medical practice, and that may constitute evidence of health care fraud, would be found in the residence.
See United States v. Srivastava,
1.
As the Suppression Ruling recognized, the Affidavit made compelling assertions that documents and records relating to Srivastava’s medical practice — and that may constitute evidence of health care fraud — would be found in the Potomac residence. Indeed, Srivastava conducted a substantial part of his medical practice from the Potomac residence: claims for medical services were submitted to health care benefit programs from the residence; the residence was used as the billing address for the medical practice; and the practice received payments from such programs, both electronically and by mail, at the residence. In these circumstances, the magistrate judge was unquestionably justified in issuing the search warrant for the Potomac residence, commanding the officers to seize a broad range of things, “including, but not limited to, financial, business, patient, insurance and other records related to the business of Dr. Pradeep Srivastava ... which may constitute evidence of [health care fraud].” J.A. 50 (emphasis added). The Affidavit established that documents and records sought from the residence — specifically (as identified in category 2 of Attachment A) Srivastava’s “l'ffinancial records, including but not limited to accounting records, tax records, accounts receivable logs and ledgers, banking records, and other records reflecting income and expenditures of the business” — related to his medical practice and constituted evidence of health care fraud. Id. (emphasis added). Finally, the categories of items designated for seizure extended to (as identified in Category 5) Srivastava’s “calend[a]rs, appointment books, correspondence, passports, visas, photographs and other documents.” Id. at 51.
2.
We turn next to the issue of whether the Potomac Documents were within the scope of the search warrant for the Potomac residence. As the Supreme Court has mandated, and our sister courts of appeals have recognized, a search warrant is not to be assessed in a hypertechnical manner.
See United States v. Ventresca,
As the district court concluded in its Suppression Ruling, “in order to fall within the scope of the warrant, [the Potomac Documents] not only had to have some relationship to' Dr. Srivastava’s business,” but were also “subject to the requirement that [they] may constitute evidence that health care fraud had been committed.”
See Srivastava,
a.
Although Srivastava argues on appeal that the. search warrant for the Potomac residence limited the authorized seizures to those documents and records that are “related to the business” (i.e., the medical practice), this contention does not undermine the constitutionality of the seizure of the Potomac Documents. Of note, Srivastava’s medical practice operated as a “Subchapter S” corporation, under which his portion of the practice’s income was passed through and taxed directly to him as an individual. 17 In such circumstances, it is difficult to realistically define a bright line between “personal financial records” and “business records,” as Srivastava implores us to do. Rather, it is consistent with both common sense and realism to deem the financial records relating to the medical practice as being nearly synonymous with the financial records of Srivastava individually. By way of example, with respect to the Potomac Documents seized from Srivastava’s bedroom:
• The IRS Form 1099 for tax year 1999 found in an envelope marked “1099 Final” constituted a financial record, as specified in category 2 of Attachment A. Under law, an IRS Form 1099 reflects income paid to a taxpayer. In this instance, the Form reflected certain interest income paid to Srivastava in 1999, which also, in these circumstances, reasonably related to his business of practicing medicine; and
• Additional IRS Forms 1099 for tax year 1998 (found in the envelope dated October 15, 1996) and for tax years 1997 and 1999 (from the folder marked “1996 Tax Info.”) likewise constituted financial records related to Srivastava and his medical practice, specified for seizure under Attachment A.
Assessed in a de novo context, the balance of the Potomac Documents also were within the ambit of the financial records specified for seizure in category 2 of Attachment A. More specifically, those records— reflecting stock and option transactions and banking activities — related to the receipt of Srivastava’s income and, thus, also reasonably related to his medical practice.
b.
We next consider the Suppression Ruling’s conclusion that the Potomac Documents were not within the scope of the search warrant for the Potomac residence because they failed to satisfy the magistrate judge’s requirement that things could only be seized if they “may constitute evidence that health care fraud had been committed.”
Srivastava,
Here, the Affidavit demonstrated probable cause that Srivastava’s medical practice had submitted fraudulent claims to health care benefit programs from the Potomac residence, suggesting that the executing officers were likely to encounter a “paper puzzle” in carrying out the command of the warrant. For example, a piece of the fraud puzzle in this case included Srivastava’s financial records, such as IRS Forms 1099 reflecting his income.
Cf. United States v. Norton,
Having made a de novo assessment of the scope of the warrant for the Potomac residence — and having done so in a nonhyperteehnieal, common-sense, and realistic manner — we are satisfied that the Potomac Documents were within the scope of its specifications. The Affidavit spelled out a complex fraud scheme, and the war
B.
Turning to the government’s contention that the Bank of India Transfers were within the scope of the search warrant issued for the Greenbelt office, we conclude that they were also erroneously suppressed by the district court. In this regard, the Suppression Ruling recognized that the Bank of India Transfers “legitimately appeared to be records of the business.”
Srivastava,
To the contrary, in following the money, the financial records of a suspect may well be highly probative of violations of a federal fraud statute.
See Shamy,
Consequently, and consistent with our conclusion that the Potomac Documents were subject to seizure under the search warrant for the Potomac residence, the Bank of India Transfers were sufficiently designated for seizure by the warrant for the Greenbelt office. As recognized by the district court, the Transfers “legitimately appeared to be records of the business.”
Srivastava,
C.
Finally, having determined that the Potomac Documents and the Bank of India Transfers were within the ambit of the search warrants for the Potomac residence and the Greenbelt office, we assess the government’s challenge to the blanket suppression of all the seized evidence. In that respect, the district court found that the warrants had been so flagrantly and unconstitutionally executed that a blanket suppression was justified. We have consistently recognized, however, that, “[a]s a general rule, if officers executing a search warrant exceed the scope of the warrant, only the improperly-seized evidence will be suppressed; the properly-seized evidence remains admissible.”
United, States v. Squillacote,
By its Suppression Ruling, the district court determined that a blanket suppression was justified because, inter alia, the executing officers had “approached the searches of Dr. Srivastava’s home and offices in a way that flagrantly exceeded the specific limitations of the warrants, and ... grossly exceeded the scope of the warrants in their execution.”
Srivastava,
Even assuming — as the district court found — that Agent Marrero believed that the terms of the search warrants were “meaningless,” and did not limit his conduct in any way, such an as
In these circumstances, the district court made errors of law in its blanket suppression of the seized evidence, necessarily abusing its discretion in that regard.

IV.
Pursuant to the foregoing, we vacate the Suppression Ruling and remand for such other and further proceedings as may be appropriate.

. Although a substantial group of documents and records were also seized in the third search (of the Oxon Hill office), and are also encompassed in the Suppression Ruling, the government does not presently propose to utilize them at trial.
. The return to Srivastava in April 2003 of approximately 80% of the things seized from the Potomac residence resulted from an agreement between the parties. In returning those records, the government did not concede that they had been improperly seized. By their agreement in this regard, the lawyers apparently obviated the need for preindictment proceedings under Rule 41(g) of the Federal Rules of Criminal Procedure. See infra note 20. As a result, the suppression issues were not litigated until early 2006.
. As mandated by Treasury Department regulations, a report must be filed with the IRS by any person in and doing business in the United States, who possesses an interest in or authority over a foreign financial account exceeding $10,000 during a calendar year. See 31 C.F.R. §§ 103.24, 103.27(c); see also 31 U.S.C. § 5315(c) (authorizing Secretary of Treasury to prescribe reporting requirements); id. § 5322 (providing criminal penalties for willful violations of Treasury Department regulations, such as those mandating foreign financial account reports).
. The indictment is found at J.A. 7-26.
. In his effort to suppress the evidence seized under the warrants, Srivastava also sought an evidentiary hearing in the district court, pursuant to
Franks v. Delaware,
maintaining that the Affidavit had affirmatively omitted material information.
See
. An IRS Form 1099 is used to report various types of income — other than wages, salaries, and tips — to the IRS. Such income includes, inter alia, dividends and distributions, interest, government payments, payments to independent contractors, and miscellaneous income.
. Although several Potomac Documents discovered in the Potomac residence were found in folders dated 1996, the Documents seized sufficiently related to the pertinent time frame.
. Intermingled with the financial records discovered in one of the folders located in the bedroom of the Potomac residence were other records of Srivastava’s medical practice, including a client master list, employee time sheets, and a memorandum relating to employee leave and vacation time. The government does not propose to offer those items into evidence.
. In the Suppression Ruling, the court observed that Agent Marrero had
provided astonishing testimony in which he indicated that he inserted [the substantive introductory language] merely as a "go by,” and that he did not consider it to limit his actions in any way. When asked if it was true that he "didn't give much thought to what this meant” and whether he "just thought it was some boilerplate that ought to be” in the warrant, [Agent] Marrero agreed "for the most part,” stat-tag only that he "knew it was used before so it was appropriate language.”
Srivastava,
. The Suppression Ruling also concluded that the documents and records that the government proposed to utilize at trial were not otherwise admissible under either the inevitable discovery or independent source exceptions to a Fourth Amendment violation.
See Srivastava,
. In accordance with the jurisdictional predicate of 18 U.S.C. § 3731, the United States Attorney has certified that this interlocutory appeal "is not taken for purposes of delay” and that the evidence excluded by the Suppression Ruling "is a substantial proof of a fact material in the proceeding.” J.A. 725.
. Although our Court has, on many occasions, applied Ventresca's "commonsense and realistic fashion” principle in analyzing the sufficiency of supporting affidavits, we do not appear to have specifically utilized this principle in assessing the scope of a search warrant. On this point, however, we readily agree with the Ninth and Tenth Circuits,
see Gorman,
. A corporation that elects to be taxed under Subchapter S, see 26 U.S.C. §§ 1361-63, pays no federal income tax, but passes all its income and losses through to its shareholders. Those shareholders then report the income or losses on their individual tax returns.
. The reasoning underlying this point — that evidence of the possession and transfer of large sums of money can, in the proper context, be a strong indicia of fraud — is further emphasized by our analysis of the district court’s erroneous suppression of the Bank of India Transfers. See infra Part III.B.
. If a false or fraudulent billing scheme has been conducted in connection with a medical practice, multiple federal fraud statutes are potentially implicated. For example, federal fraud offenses that might be pursued on the basis of a factual scenario arising from a health care fraud scheme include, inter alia, mail fraud (18 U.S.C. § 1341), wire fraud (18 U.S.C. § 1343), tax fraud (26 U.S.C. §§ 7201, 7206), and health care fraud (18 U.S.C. § 1347). Ftealth care fraud is simply one species of such a scheme, which Congress saw fit to combat through its 1996 enactment of § 1347.
. The Suppression Ruling also invoked the government’s voluntary return of approximately 80% of the documents and records seized from the Potomac residence,
see supra
note 6, to support its finding that the officers had flagrantly disregarded the scope of the search warrants.
See Srivastava,
. Because we are satisfied that the Potomac Documents and the Bank of India Transfers were within the scope of the search warrants, we need not address the government’s final contention- — that the evidence generated during the IRS investigation was derived from an independent source.
