delivered the opinion of the Court.
Undеr a rule adopted by the Commissioner of Social Security, in determining whether a claimant is entitled to Social Security disability benefits, special weight is accorded opinions of the claimant’s treating physician. See 20 CFR §§ 404.1527(d)(2), 416.927(d)(2) (2002). This case presents the question whether a similar “treating physician rule” applies to disability determinations under employee benеfits plans covered by the Employee Retirement Income Security Act of 1974 (ERISA or Act), 88 Stat. 882, as amended, 29 U. S. C. § 1001 et seq. We hold that plan administrators are not obliged to accord special deference to the opinions of treating physicians.
ERISA and the Secretary of Labor’s regulations under the Act require “full and fair” assessment of claims and clear communication to the claimant of the “specific reasons” for benefit denials. See 29 U. S. C. § 1133; 29 CFR §2560.503-1 (2002). But these measures do not command plan administrators to credit the opinions of treating physicians over other evidence relevant to the claimant’s medieal condition. Because the Court of Appeals for the Ninth Circuit erroneously applied а “treating physician rule” to a disability plan governed by ERISA, we vacate that court’s judgment and remand for further proceedings.

Petitioner Black
&
Decker Disability Plan (Plan), an ERISA-governed employee welfare benefit plan, covers employees of Black
&
Decker Corporation (Black & Decker) and certain of its subsidiaries. The Plan provides benefits for eligible employees with a “disability.” As relevant here, the Plan defines “disability” to mean “the complete inability ... of a Participant to engage in his regular occupation with
*826
the Employer.”

Respondent Kenneth L. Nord was formerly employed by a Black & Decker subsidiary as a material planner. His job, classed “sedentary,” required up to six hours of sitting and two hours of standing or walking per day. Id., at 826.
In 1997, Nord consulted Dr. Leo Hartman about hip and back pain. Dr. Hartman determined that Nord suffers from a mild degenerative disc disease, a diagnosis confirmed by a Magnetic Resonance Imaging scan. After a week’s trial on pain medication prescribed by Dr. Hartman, Nord’s condition remained unimproved. Dr. Hartman told Nord to cease work temporarily, and recommended that he consult an orthopedist while continuing to take the pain medication.
Nord submitted a claim for disability benefits under the Plan, which MetLife denied in February 1998. Nord next exercised his right to seek further consideration by Met-Life’s “Group Claims Review.” Id., at 827. At that stage, Nord submitted letters and supporting documentation from Dr. Hartman and a treating orthopedist to whom Hartman had referred Nord. Nord also submitted a questionnaire form, drafted by Nord’s counsel, headed “Work Capacity Evaluation.” Black & Decker human resources representa *827 tive Janmarie Forward answered the questions, as the form instructed, by the single word “yes” or “no.” One of the six items composing the “Work Capacity Evaluation” directed Forward to “[a]ssume that Kenneth Nord would have a moderate pain that would interfere with his ability to perform intense interpersonal communications or to act appropriately under stress occasionally (up to one-third) during the day.” Lodging for Pet. for Cert. L-37. The associated question asked whether an “individual of those limitations [could] perform the work of a material planner.” Ibid. Forward marked a space labeled “no.”
During the MetLife review process, Black & Decker referred Nоrd to neurologist Antoine Mitri for an independent examination. Dr. Mitri agreed with Nord’s doctors that Nord suffered from a degenerative disc disease and chronic pain. But aided by pain medication, Dr. Mitri concluded, Nord could perform “sedentary work with some walking interruption in between.” Id., at L-45. MetLife thereafter made a final recommendation to deny Nord’s clаim.
Black & Decker accepted MetLife’s recommendation and, on October 27,1998, so informed Nord. The notification letter summarized the conclusions of Nord’s doctors, the results of diagnostic tests, and the opinion of Dr. Mitri. See id., at L-155 to L-156. It also recounted that Black & Decker had forwarded Dr. Mitri’s report to Nord’s counsel with a request for comment by Nord’s attending physician. Although Nord had submitted additional informаtion, the letter continued, he had “provided ... no new or different information that would change [MetLife’s] original decision.” Id., at L-156. The letter further stated that the Work Capacity Evaluation form completed by Black & Decker human resources representative Forward was “not sufficient to reverse [the Plan’s] decision.” Ibid.
Seeking to overturn Black & Decker’s determination, Nord filed this aсtion in Federal District Court “to recover benefits due to him under the terms of his plan.” 29 U. S. C. *828 § 1132(a)(1)(B). On cross-motions for summary judgment, the District Court granted judgment for the Plan, concluding that Black & Decker’s denial of Nord’s claim was not an abuse of the plan administrator’s discretion.
The Court of Appeals for the Ninth Circuit roundly reversed and itself “grant[ed] Nord’s motion for summary judgment.”
We granted certiorari,
► — (
The treating physician rule at issue here was originally developed by Courts of Appeals as a means to control disability determinations by administrative law judges under the Social Security Act, 49 Stat. 620, 42 U. S. C. § 231 et seq. See Macсaro, The Treating Physician Rule and the Adjudication of Claims for Social Security Disability Benefits, 41 Soc. Sec. Rep. Serv. 833, 833-834 (1993). In 1991, the Commissioner of Social Security adopted regulations approving and formalizing use of the rule in the Social Security disability program. See 56 Fed. Reg. 36961, 36968 (codified at 20 CFR §§ 404.1527(d)(2), 416.927(d)(2) (2002)). The Social Security Administration, the regulations inform, will generally “give more wеight to opinions from ... treating sources,” and “will always give good reasons in our notice of determination or decision for the weight we give your treating source’s opinion.” §§ 404.1527(d)(2), 416.927(d)(2).
Concluding that a treating physician rule should similarly govern private benefit plans under ERISA, the Ninth Circuit said in
Regula
that its “reasons ha[d] to do with common sense as well as consistency in [judicial] review of disability determinations where benefits are protected by federal law.”
“ERISA was enacted to promote the interests of employees and their beneficiaries in employee benefit plans, and to protect contractually defined benefits.”

v.
Bruch,
ERISA empowers the Secretary of Labor to “prescribe such regulations as he finds necessary or appropriate to carry out” the statutory provisions securing employee benefit rights. § 1135; see § 1133 (plans shall process claims “[i]n accordance with regulations of the Secretary”). The Secretary’s regulations do not instruct plan administrators to accord extra respect to treating physicians’ opinions. See 29 CFR §2560.503-1 (1997) (regulations in effect when Nord filed his claim); 29 CFR § 2560.503-1 (2002) (current regulations). Notably, the most recent version of the Secretary’s regulations, which installs no treating physician rule, issued more than nine years after the Social Security Administration codified a treating physician rule in that agency’s regulations. Compare 56 Fed. Reg. 36932, 36961 (1991), with 65 Fed. Reg. 70265 (2000).
If the Secretary of Labor found it meet to adopt a treating physician rule by regulation, courts would examine that determination with appropriate deference. See

v.
Spink,
Plan administrators, of course, may not arbitrarily refuse to credit a claimant’s reliable evidence, including the opinions of a treating physician. But, we hold, courts have no warrant to require administrators automatically to accord special weight to the opinions of a claimant’s physician; nor may cоurts impose on plan administrators a discrete burden of explanation when they credit reliable evidence that conflicts with a treating physician’s evaluation. 4 The Court of Appeals therefore erred when it employed a treating physician rule lacking Department of Labor endorsement in holding that Nord was entitled to summary judgment.

For the reasоns stated, the judgment of the United States Court of Appeals for the Ninth Circuit is vacated, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
The Plan sets out a different standard for determining whether an employee is entitled to benefits for a period longer than 30 months. Because respondent Nord sought benefits “for up to 30 months,”
The Plan sought review only of the Court of Appeals’ holding “that an ERISA disability plan administrator’s determination of disability is subject to the ‘treating physician rule.’” Pet. for Cert. i. We express no opinion on any other issues.
The treating physician rule has not attracted universal adherence outside the Social Security context. Sоme courts have approved a rule similar to the Social Security Commissioner’s for disability determinations under the Longshore and Harbor Workers’ Compensation Act, 33 U. S. C. § 901
et seq.,

e. g., Pietrunti
v.
Director, Office of Workers’ Compensation Programs,
Nord asserts that there are two treating physician rules: a “procedural” rule, which requires a hearing officer to explain why she rejectеd the opinions of a treating physician, and a “substantive” rule, which requires that “more weight” be given to the medical opinions of a treating physician. Brief for Respondent 12-13 (internal quotation marks omitted). In this case, Nord contends, the Court of Appeals applied only the “procedural” version of the rule.
