Abbott Radiology Associates, et al. (“Plaintiffs”), appeal from a judgment of the United States District Court for the Western District of New York (Carol E. Heckman, Magistrate Judge) entered November 20, 1997 in accordance with a decision and order of the same day granting summary judgment in favor of Donna E. Shalala, as Secretary of the Department of Health and Human Services (the “Secretary”), and the Department of Health and Human Services (together with the Secretary “Defendants”). Abbott Radiology Assocs. v. Shalala, 992 F.Supp. 212 (W.D.N.Y. 1997).

On May 23, 1994, Plaintiffs commenced this action against Defendants, alleging that the Secretary had improperly calculated Plaintiffs’ reimbursement for services rendered under the Medicare statute and regulations by applying the doctrine of “comparability.” See 42 U.S.C. § 1395u(b)(3)(B); 42 C.F.R. § 405.508. After a series of adverse carrier rulings, Plaintiffs sought a hearing before a Health And Human Services (“HHS”) Administrative Law Judge (“ALJ”), which was held on March 24 and 25, 1992. On June 25, 1992, ALJ Margaret Quinn denied Plaintiffs’ requests for review and reopening of their reimbursement determinations. Plaintiffs’ appeal to the HHS Appeals Council was unsuccessful.1 In a November 20, 1997 decision and order, Magistrate Heckman affirmed ALJ Quinn’s June 25, 1992 determination.

On appeal, Plaintiffs make substantially the same arguments asserted before the Magistrate Judge, which can be summarized as follows: (1) the Secretary’s comparability policy is inconsistent with and in violation of the comparability statute and regulation; (2) the Secretary’s interpretation of the Medicare statute and regulation represents an arbitrary and capricious alteration unsupported by a justification in the administrative record; (3) the ALJ’s decision finding that the carrier “took into account” physician charges when setting its private insurance plan rates of reimbursement and the Magistrate’s affirmance of the ALJ were not supported by substantial evidence; (4) the Sec*139retary violated the Administrative Procedure Act and Medicare statute by failing to promulgate her interpretation of the comparability policy by notice and comment rulemaking; and (5) the ALJ’s decision and the Magistrate’s affirmance erred in denying Plaintiffs’ request for reopening of claims arising from reimbursement determinations made between October 1, 1985 and March 29, 1989. As a result of all these arguments, Plaintiffs contend that the Magistrate erred in according deference to the Secretary’s interpretation of the statute and regulation at issue.

We review the district court’s affir-mance of the ALJ’s ruling de novo. See Townley v. Heckler, 748 F.2d 109, 112 (2d Cir. 1984). In doing so, we review the ALJ’s decision to determine whether it applied the correct legal principles and is supported by “substantial evidence.” See, e.g., Johnson v. Bowen, 817 F.2d 983, 985 (2d Cir. 1987).

We affirm the judgment of the district court for substantially the same reasons stated in the Magistrate Judge’s thorough decision.

The judgment of the district court is AFFIRMED.
