OPINION
Defendant, Jeffrey B. Lewis, appeals the judgment of conviction and sentence entered following his guilty plea to one count of mail fraud, in violation of 18 U.S.C. § 1341, and one count of conspiring to distribute narcotics, in violation of 21 U.S.C. § 846, in connection with a scheme to defraud the Medicaid program. Defendant contends in this appeal that the District Court erred in applying enhancements for use of a special skill, pursuant to U.S.S.G. § 3B1.3, and for more than minimal planning, pursuant to U.S.S.G. *658 § 2F1.1(b)(2). Because we conclude that the District Court did not err in applying either of the enhancements, we AFFIRM the defendant’s sentence.
I.
Jeffrey Lewis is licensed as a Doctor of Dental Medicine in the State of Kentucky and operates a private dental practice in Manchester, Kentucky. From July, 1991 through December, 1994, defendant submitted to the Kentucky Medical Assistance Program thousands of Medicaid Statement Dental Forms by mail certifying that he had performed dental procedures on Medicaid patients which he had in fact not performed. In accordance with his submissions, defendant received $1,000,000 in over-payments from Medicaid and the Kentucky Medical Assistance Program. To maximize his return, defendant submitted thousands of claims for complicated and, therefore, expensive procedures. For example, defendant’s practice submitted 89% of the total billings received by the State of Kentucky for “removal of a foreign body.” While a dentist employed by defendant submitted only 114 billings for this procedure, the defendant submitted 2,684 billings. Similarly, defendant’s clinic accounted for 64% of all billings by Medicaid dental providers in the State of Kentucky for a complicated impaction procedure. To attract additional patients who qualified for Medicaid and thereby further his fraudulent scheme, defendant offered impoverished patients medically unnecessary prescriptions for Schedule III narcotics. In total, defendant prescribed 9,921 illegitimate prescriptions for Schedule III narcotics.
As a result of his fraudulent scheme, on January 15, 1997, a federal indictment was returned against defendant charging him with six counts of mail fraud, in violation of 18 U.S.C. § 1341, one count of conspiracy to distribute narcotics, in violation of 21 U.S.C. § 846, and nine counts of distribution of narcotics, in violation of 21 U.S.C. § 841(a)(1). Pursuant to a written plea agreement, the government dismissed the indictment and filed an information charging defendant with one count of mail fraud and one count of conspiring to distribute narcotics. In imposing a sentence of thirty months’ imprisonment to be followed by a three-year term of supervised release, the District Court enhanced defendant’s sentence for use of a special skill pursuant to § 3B1.3 of the Guidelines and for more than minimal planning pursuant to § 2F1.1(b)(2) of the Guidelines, despite defendant’s objections. Reserving the right in the plea agreement to challenge the application of the aforementioned enhancements, defendant now appeals.
II.
We review the District Court’s legal conclusions regarding the application of Sentencing Guidelines
de novo;
whereas; the District Court’s findings of fact are accepted unless they are clearly erroneous.
See United States v. Gort-DiDonato,

A. U.S.S.G. § 3B1.3: Use of a Special Skill
In defendant’s first assignment of error, defendant contests the District Court’s application of the § 3B1.3 enhancement for abuse of a special skill to the mail fraud conviction. Defendant contends that the District Court erred in applying § 3B1.3 because, although he possessed a special skill, his special skill did not facilitate the commission of mail fraud. “We review a district court’s factual finding regarding application of § 3B1.3 for clear error.”
United States v. Atkin,
U.S.S.G. § 3B1.3 provides that an offense level may be increased by two levels “[i]f the defendant ... used a special skill, in a man *659 ner that significantly facilitated the commission or concealment of the offense[.]” A special skill “refers to a skill not possessed by members of the general public and usually requiring substantial education, training or licensing.” U.S.S.G. § 3B1.3, comment, (n.2). Enumerated in the commentary as examples are “pilots, lawyers, doctors, accountants, chemists, and demolition experts.” U.S.S.G. § 3B1.3, comment, (n.2). Defendant does not dispute that his medical license constitutes a special skill as doctors are specifically listed as an example of a special skill in the commentary to § 3B1.3.
However, to apply the enhancement to defendant’s mail fraud offense, we must find that his occupation as a dentist made “it significantly ‘easier’ for him to commit ... the crime.”
United States v. Atkin,
Weinstock did not use his podiatric skills to facilitate the crime. Although performing unnecessary medical procedures requires a special skill, refraining from providing such services and falsely billing therefore does not.
Id. at 281. While we concluded in Weinstock that falsely billing an insurance company for services not performed does not require a special skill, Lewis did not merely bill for services he did not perform. Rather, as the Presentenee Investigation Report indicates, Lewis performed procedures on patients and then exaggerated the nature of the procedures in his billings to Medicaid. Unlike simply billing for a procedure that has not been performed, exaggerating the nature of a medical procedure does require the use of special medical knowledge. We, therefore, conclude that the District Court did not err in applying the § 3B1.3 enhancement to defendant’s sentence.
B. U.S.S.G. § 2F.l.l(b)(2): More Than Minimal Planning
In his second assignment of error, defendant contends that the District Court erred in applying a two level adjustment for more than minimal planning pursuant to § 2F1.1 of the Sentencing Guidelines. The District Court’s application of § 2Fl.l(b)(2) is a finding of fact which we review for clear error.
See United States v. Milligan,
To further support his argument that the District Court erred in applying § 2Fl.l(b)(2), defendant contends that the enhancement is inappropriate because, by merely mailing false claims, he committed mail fraud in only its simplest form; we,
*660
however, rejected the identical argument in
Ellerbee.
As we stated, “[m]ore than minimal planning does not require that the offense be committed in its most complicated form, as appellant impliedly argues; rather it just must be something more than the crime in its simplest form. ‘More than minimal planning’ can be deduced by ... repeated acts.”
Ellerbee,
Defendant claims, however, that we may not deem present more than minimal planning whenever the offender has engaged in repeated acts which are other than opportune because to do so creates a mandatory presumption violative of his due process rights. “[Cjommentary in the Guidelines Manual that interprets or explains a guideline is authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.”
Stinson v. United States,
Accordingly, we conclude that the District Court did not err in enhancing defendant’s sentence for more than minimal planning pursuant to § 2Fl.l(b)(2).
IV.
For the foregoing reasons, the defendant’s sentence is AFFIRMED.
