ORDER AND JUDGMENT *
PAUL KELLY, JR., Circuit Judge.
Kathy L. Poppa appeals from an order of the district court affirming the Commissioner’s decision denying her application for supplemental security income (SSI) benefits. The claim at issue in this appeal was filed on January 20, 2004, alleging disability since June 1, 2002. 1 The agency denied Ms. Poppa’s application initially and on reconsideration. Ms. Poppa received a de novo hearing before an administrative law judge (ALJ). Because the ALJ concluded that Ms. Poppa had the residual functional capacity (RFC) for sedentary work and that she could perform a significant number of jobs in the national economy, he denied her claim for SSI benefits. The Appeals Council denied review and Ms. Poppa appealed to the district court. The district court reversed and remanded for further findings.
On remand, Ms. Poppa had another hearing before a different ALJ. Ms. Poppa submitted additional evidence at the hearing. The second ALJ determined that Ms. Poppa had severe impairments from spine and knee arthritis, mental disorders, fibromyalgia, and carpal tunnel but he concluded that none of the impairments or combination of impairments met or equaled any of the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1. The ALJ found that Ms. Poppa had the RFC to perform a limited range of light exertional work. He denied Ms. Poppa’s application for benefits, concluding that she was not disabled at step five of the analysis because she could perform a significant number of jobs in the national economy.
See Williams v. Bowen,
We have jurisdiction under 28 U.S.C. § 1291 and 42 U.S.C. § 405(g). Because the Appeals Council declined to review Ms. Poppa’s appeal after the second ALJ denied her claim for benefits, that ALJ’s decision is the Commissioner’s final decision for purposes of our review.
See Doyal v. Barnhart,
Res Judicata and the Law of the Case Doctrine
Ms. Poppa contends that the second ALJ’s decision violated either res judicata or the law of the case doctrine because those doctrines precluded the second ALJ from relitigating the issue of her RFC after it was established in the first ALJ’s decision. We disagree with Ms. Poppa’s contention.
Res judicata applies in the social security context when there has been a “previous determination or decision ... about [the claimant’s] rights on the same facts and on the same issue or issues, and this previous determination has become final by either administrative or judicial action.” 20 C.F.R. § 416.1457(c)(1) (emphasis added). Here the first ALJ’s decision does not constitute a final decision for the purposes of res judicata because Ms. Poppa sought review of the first ALJ’s decision from the Appeals Council and then the district court. See id. § 416.1455(b) (explaining that an ALJ’s decision is binding on all parties to the hearing unless the claimant requests review of the decision by the Appeals Council, the Appeals Council denies review, and the claimant seeks judicial review in district court).
Our conclusion that administrative res judicata does not apply in this case is consistent with our precedent.
See Hamlin v. Barnhart,
The second ALJ’s RFC determination likewise does not violate the principles of the law of the case doctrine. Under that doctrine, an “administrative agency, on remand from a court, [must] conform its further proceedings in the case to the principles set forth in the judicial decision.... ”
Copart, Inc. v. Admin. Review Bd., U.S. Dep’t of Labor,
On remand, the district court instructed the ALJ to reconsider Ms. Poppa’s credibility applying the relevant factors from SSR 96-7p and to make findings linked to evidence in the record.
2
The regulations require that an ALJ’s RFC be based on the entire case record, including the objective medical findings and the credibility of
*1171
the claimant’s subjective complaints.
See
20 C.F.R. §§ 416.929, 416.945. Since the purpose of the credibility evaluation is to help the ALJ assess a claimant’s RFC, the ALJ’s credibility and RFC determinations are inherently intertwined. A new determination on Ms. Poppa’s credibility necessarily required reassessment of the RFC. Because there was no explicit or implicit decision by the district court on the validity of the first ALJ’s RFC determination, the second ALJ was free to reassess the RFC on remand without violating the law of the case doctrine.
Cf. Campbell,
The RFC Assessment
Ms. Poppa argues that substantial evidence does not support the second ALJ’s RFC finding because (1) no exceptions to the law of the case doctrine apply and the second ALJ was bound by the first ALJ’s RFC finding; (2) the ALJ’s assessment of her credibility was flawed; and (3) the opinion evidence considered by the ALJ does not support an RFC for light work.
We note initially that we will not address Ms. Poppa’s first issue. Because we conclude that the second ALJ’s decision did not violate the law of the case doctrine, we do not need to address whether an exception to that doctrine applies.
Credibility Determination
Ms. Poppa argues that the ALJ’s credibility determination was flawed. Ms. Poppa asserts that the ALJ erred because he did not consider the relevant factors.as required by SSR 96-7p. Our precedent “does not require a formalistic factor-by-factor recitation of the evidence ... [s]o long as the ALJ sets forth the specific evidence he relies on in evaluating the claimant’s credibility.”
Qualls v. Apfel,
Ms. Poppa also disputes the ALJ’s conclusion that Ms. Poppa has shown drug-seeking behavior and that this impacted her credibility. She argues that “[i]n the entire record there is only one reference to possible inappropriate use of pain medications — a single entry on July 26, 2005 that Poppa had a history of ‘ “pain medication seeking as well as Soma seeking requests.” ’ ” Aplt. Br. at 28 (quoting Aplt.App., Vol. II at 533). Ms. Poppa’s statement is not accurate because the ALJ referenced other record evidence to support his conclusion about Ms. Poppa’s drug-seeking behavior. For example, in discussing an August 19, 2005 doctor’s visit, the ALJ noted that Ms. Poppa
*1172 wanted to increase her Oxycontin to three times a day, which was against clinic policy and against recommended dosing. She also said she was going on vacation and wanted Lortab to use when her Oxycontin ran out. She was vague about how long she would be gone on vacation (2-3 weeks). [The doctor] refused to prescribe the Lortab and also refused her request to post date the prescription.
Aplt.App., Vol. II at 401. The ALJ noted also that on February 23, 2006, Ms. Poppa “initiated [a] higher dose of Oxycontin on her own,” and that on December 29, 2006, “she again asked for a post dated narcotic prescription.” M 4 Contrary to Ms. Poppa’s assertion that the only evidence of drug-seeking behavior is a “single, isolated remark in the record,” Aplt. Br. at 29, there is sufficient evidence in the record to support the ALJ’s determination that Ms. Poppa’s credibility about her pain and limitations was compromised by her drug-seeking behavior.
Opinion Evidence
Ms. Poppa asserts that the opinion evidence considered by the ALJ does not support a light RFC. The ALJ noted that the most recent agency experts to review the evidence found Ms. Poppa able to perform light work with certain limitations. That evaluation took place in April 2004. Ms. Poppa argues that the ALJ’s reliance on this evaluation is misplaced because the evaluation occurred before the first ALJ found Ms. Poppa limited to sedentary work. She continues to argue that the second ALJ was bound by the first ALJ’s decision. As we have discussed previously, we are not persuaded by this argument.
Ms. Poppa argues also that the ALJ improperly dismissed a January 2003 opinion of a state agency evaluator in which the evaluator determined that Ms. Poppa had an RFC for sedentary work. The ALJ appeared to give diminished weight to the earlier opinion because the evaluation was performed before Ms. Poppa completed her current application and did not take into account the subsequent evidence that showed improvement in her condition after her two back surgeries in early 2005. 5 Without citing to specific record evidence, Ms. Poppa argues generally that the evidence does not show that her condition improved significantly after her 2005 surgeries.
*1173 The ALJ’s discussion, however, includes references to record evidence that supports his conclusion that Ms. Poppa’s condition improved after the surgeries in early 2005 and that therefore the January 2003 opinion was entitled to less weight. For example, the ALJ noted that at Ms. Poppa’s July 12, 2005 visit to the clinic, the nurse practitioner stated that Ms. Poppa “appeared to be without significant pain.” Aplt.App., Vol. II at 402. The ALJ noted further that at her November 1, 2005 visit, Ms. Poppa “had relatively full range of motion in her upper extremity neck and shoulder area and minimal decrease in range of motion in the lower back area” and that “[djespite increasing complaints of chronic pain in connection with her requests for continuing medication, the leg lift tests were all negative after surgery.” Id. at 403. Finally, at her July 11, 2006 visit, the ALJ noted that Ms. Poppa “was able to function fairly well with pain management.” Id.
The ALJ did not err in his consideration of the opinion evidence.
Social Security Ruling OO-kp
Ms. Poppa argues that the ALJ erred in not complying with SSR 00-4p, which requires that an ALJ must inquire about and resolve any conflicts between a Vocational Expert’s (VE) testimony regarding a job and the description of that job in the Dictionary of Occupational Titles (4th ed. 1991) (DOT). 6 Although we agree that the ALJ erred by not inquiring about whether there were any conflicts between the VE’s testimony about the job requirements for the jobs identified and the job descriptions in the DOT, we conclude that this error was harmless because there were no conflicts.
Ms. Poppa asserts that there were two conflicts between the VE’s testimony and the DOT and that the ALJ erred by not having the VE give a reasonable explanation for these apparent conflicts. After the ALJ gave the VE a hypothetical with all of the limitations that were ultimately included in Ms. Poppa’s RFC, the VE came up with two jobs: “Cleaner, Housekeeping” (DOT 323.687-014), and “Mail Clerk” (DOT 209.687-026).
Ms. Poppa notes that in the job description for “Cleaner, Housekeeping,” it states: “ ‘Performs other duties as described under CLEANER (any industry) I Master Title.’” Aplt. Br. at 33 (quoting DOT 323.687- 014,
Ms. Poppa notes that the second job identified by the VE, “Mail Clerk,” requires frequent reaching, handling, and fingering.
See
DOT 209.687-026,
Because there were no conflicts between the VE’s testimony and the DOT’s job descriptions, the ALJ’s error in not inquiring about potential conflicts was harmless.
See Massachi v. Astrue,
The judgment of the district court is AFFIRMED.
Notes
After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R.App. P. 32.1 and 10th Cir. R. 32.1.
. Ms. Poppa filed four prior applications for benefits in 1994, 1996, 1997, and 2002. All of her prior applications were denied and are not at issue in this appeal.
. The district court also instructed the ALJ to reconsider and make specific findings about (1) Ms. Poppa’s mental impairment, (2) her claim that she was disabled by a combination of impairments, and (3) whether she met Listing 1.04 for disorders of the spine. Ms. Poppa does not challenge the second ALJ's decision on these issues.
. The ALJ discussed Ms. Poppa’s daily activities, see Aplt.App., Vol. II at 402; her pain and other symptoms, see id. at 400-02; the factors that aggravate her symptoms, see id. at 401-02; the type, dosage and effectiveness of her medications, see id. at 400-01; other measures that provide relief from her symptoms, see id. at 401; and other factors concerning her functional limitations and restrictions due to pain, see, e.g., at 400 (noting that Ms. Poppa’s straight leg raising was positive before surgery and has been negative since the surgery); id. (noting nurse practitioner’s statement that Ms. Poppa "had a longstanding history of pain medication seeking as well as Soma seeking requests”); id. at 402 (noting that physician did not give full weight to Ms. Poppa's reported pain symptoms).
. There are additional references in the record that support the ALJ’s conclusion that Ms. Poppa was exhibiting drug-seeking behavior. See Aplt.App., Vol. II at 539-40 (noting that Ms. Poppa came to the clinic “requesting pain medication as well as [S]oma” because she "lost” her prescription; the clinic refused to provide her with any more pain medication until they heard back from her doctor); id. at 526 (noting that it appeared as though Ms. Poppa was in compliance with her pain contract, but that they would continue to monitor her "because in the recent past [she] has requested extra medication for traveling and/or losing it so we just want to make sure that we are on top of the situation here”); id. at 499 (noting that Ms. Poppa requested additional pain medication "Percocet or something for breakthrough pain,” even though she was already taking OxyContin; she was informed that she would not be getting any other narcotics or muscle relaxants); and id. at 476 (noting that Ms. Poppa "has tried many, many medications and it appears from communication with Utah Medicaid that despite the fact that some of the medications are not being used that the patient is getting them filled” and that Ms. Poppa’s current medication plan would be communicated to the pharmacy so that her medications "are dispensed appropriately and correctly”).
. The ALJ incorrectly stated that the surgeries took place in "early 2004,” Aplt.App., Vol. II at 403-04, but we agree with the Commissioner that this was a mere scrivener’s error and did not affect the outcome of the case. The ALJ had noted the correct date of the surgeries earlier in his decision. See id. at 402.
. The ruling at issue states:
When a VE ... provides evidence about the requirements of a job or occupation, the adjudicator has an affirmative responsibility to ask about any possible conflict between that VE ... evidence and information provided in the DOT. In these situations, the adjudicator will:
Ask the VE ... if the evidence he or she has provided conflicts with information provided in the DOT; and If the VE's ... evidence appears to conflict with the DOT, the adjudicator will obtain a reasonable explanation for the apparent conflict. SSR 00-4p,2000 WL 1898704 , at *4 (emphasis added). Our precedent is consistent with this ruling. See Haddock v. Apfel,196 F.3d 1084 , 1087 (10th Cir.1999) ("[Bjefore an ALJ may rely on expert vocational evidence as substantial evidence to support a determination of nondisabilily, the ALT must ask the expert how his or her testimony as to the exertional requirement of identified jobs corresponds with the [DOT], and elicit a reasonable explanation for any discrepancy on this point.” (emphasis added)).
