Plaintiff Marcell Cleinow filed this action pursuant to 42 U.S.C. § 405(g), requesting *684judicial review of the final decision of the Acting Commissioner of the Social Security Administrator ("Commissioner"), denying his claim for Supplemental Security Income ("SSI"). This Court referred the case to United States Magistrate Judge Marilyn Heffley, who issued a Report and Recommendation ("R & R") that the Commissioner's decision be affirmed. Plaintiff has filed objections to the R & R. For reasons discussed below, the objections will be overruled and the R & R approved and adopted.
In denying Plaintiff's claim for SSI, the Administrative Law Judge ("ALJ") found that Plaintiff suffered from osteoarthritis of the left knee, obesity, asthma, and major depression. The ALJ concluded that despite these conditions, Plaintiff retained the residual functional capacity ("RFC") to perform "medium work," as defined in 20 C.F.R. § 404.1567(c), with certain restrictions,2 and could perform jobs available in the national economy, such as assembly work, kitchen helper positions, and various packing positions. In reaching these conclusions, the ALJ afforded little weight to the opinion of Plaintiff's treating physician, Dr. Suzette Barreto, that he was capable of sitting for up to only two hours, standing or walking for only four hours, would need to alternate between sitting and standing every hour, and would miss four or more days of work per month due to his impairments and/or treatments.3 The ALJ found that these opinions were not supported by the record as a whole, including Dr. Barreto's treatment notes.4
Plaintiff sought review of the ALJ's findings as to his physical impairments only, contending that the ALJ erred in assigning little weight to Dr. Barreto's opinion, and in declining to seek a consultative evaluation. The R & R considered the medical records as a whole in concluding that the ALJ did not err in discounting Dr. Barreto's opinion, and that under the circumstances, the ALJ was not obligated to order a comprehensive consultation. Plaintiff now objects to the R & R with respect to the ALJ's treatment of Dr. Baretto's opinion on three grounds. The Court addresses each of the objections in turn.
First, Plaintiff objects that the R & R fails to address her argument that the ALJ was required under SSR 96-5p and other regulations to make every reasonable effort to contact Dr. Barreto to clarify inconsistencies between her opinion and the medical records. But courts in this district have consistently rejected this argument, and concluded that "the regulation makes clear that the ALJ only need re-contact the medical source when the evidence received from the medical source is inadequate to determine whether or not the claimant is disabled, not because the ALJ finds the doctor's opinion inconsistent with the claimant's medical records."5 Accordingly, *685the ALJ did not err by discounting Dr. Barreto's opinion without contacting her to address inconsistencies between her opinion and the record.
Second, Plaintiff asserts that contrary to the R & R's conclusion, an ALJ is obligated to determine whether to assign controlling weight to the medical opinion of a treating physician before considering whether the opinion is supported by evidence or is consistent with the record as a whole pursuant to 20 C.F.R. § 404.1527(c). However, the Third Circuit has held that an ALJ "may afford a treating physician's opinion more or less weight depending upon the extent to which supporting explanations are provided."6 Here, the ALJ's determination that the opinion was entitled to less weight was supported by substantial evidence for the reasons set out in detail in the R & R.
Third, Plaintiff asserts that contrary to the R & R's conclusion, an ALJ's RFC findings must be based on at least one medical opinion in order to be supported by substantial evidence. In so arguing, Plaintiff relies on the Third Circuit's decision in Doak v. Heckler ,7 which held that an ALJ's conclusion that a plaintiff was able to perform light work was not supported by substantial evidence because "[n]o physician suggested that the activity Doak could perform was consistent with the definition of light work."8 But Doak does not stand for the proposition that an ALJ cannot make an RFC determination in the absence of a medical opinion reaching the same conclusion. Such a rule would be inconsistent the Third Circuit's express holding that "[t]he ALJ-not treating or examining physicians or State agency consultants-must make the ultimate disability and RFC determinations."9 Rather, the Court in Doak held that the ALJ's opinion was unsupported because nothing in the record, which consisted of testimony and three medical reports, justified the ALJ's conclusion.10 Contrary to Plaintiff's contention, the more recent, nonprecedential Third Circuit and district court opinions on which the R & R relies clarify, rather than contradict, Doak's holding, and make clear that an ALJ is not restricted to adopting the conclusions of a medical opinion in making an RFC determination.11 As explained *686in detail in the R & R, the ALJ properly considered Plaintiff's medical records as a whole in determining Plaintiff's RFC, and was not required to rely on a specific medical opinion.
For these reasons, Plaintiff's objections to the R & R are overruled and the R & R will be approved and adopted.
AND NOW, this 30th day of April 2018, upon consideration of Plaintiff's Request for Review, Defendant's Response, the Report and Recommendation of United States Magistrate Judge Marilyn Heffley, Plaintiff's Objections to the Report and Recommendation, and Defendant's Response thereto, and after a careful, independent review of the complete administrative record, it is hereby ORDERED that:
1. The Clerk is directed to REMOVE the case from civil suspense;
2. Plaintiff's Objections to the R & R [Doc. No. 15] are OVERRULED.
3. The Report and Recommendation [Doc. No. 14] is APPROVED AND ADOPTED.
4. Consistent with the R & R, the relief sought in Plaintiff's Request for Review [Doc. No. 9] is DENIED, and the decision of the Commissioner is AFFIRMED.
It is so ORDERED.
