The opinion of the court was delivered by: Patrick J. Walsh United States Magistrate Judge
MEMORANDUM OPINION AND ORDER
Before the Court is Plaintiff's appeal of a decision by Defendant Social Security Administration ("the Agency"), denying her application for Disability Insurance benefits ("DIB"). Plaintiff claims that the Administrative Law Judge ("ALJ") erred by not considering all of the medical evidence. (Joint Stip. at 4-7, 17-19.) For the following reasons, the Agency's decision is affirmed.
II. SUMMARY OF FACTS AND PROCEEDINGS
In December 1998, Plaintiff was struck by a patient while working as a nurse's assistant and sustained neck and low back injuries. (Administrative Record ("AR") 126, 319, 655.) She underwent a cervical discectomy and fusion in September 1999. (AR 158-59.) When her condition did not improve, she underwent surgery in April 2000 for a cervical fusion and plating of the cervical spine. (AR 126-27, 138-39.)
In 2004, Plaintiff applied for DIB, alleging that she had been unable to work since December 1998, due to anxiety, depression, fibromyalgia, severe back pain, and cervical and lumbar spine impairments. (AR 74-76, 109-15.) The Agency denied the application initially and on reconsideration. (AR 61-73.) Plaintiff then requested and was granted a hearing before an ALJ. (AR 48-53, 56.) Plaintiff appeared with counsel and testified at the hearing on September 18, 2006. (AR 647-83.)
On December 27, 2006, the ALJ issued a partially favorable decision, finding that Plaintiff was disabled from September 1, 1999 to September 1, 2000, but that her condition improved after September 1, 2000 and she was no longer disabled. (AR 35-47.) The ALJ concluded that, though Plaintiff could not perform her past work as a certified nurse's assistant after September 1, 2000, she was capable of performing other jobs. (AR 45-46.)
Plaintiff appealed to the Appeals Council, which granted review. (AR 30, 32, 637-40.) The Appeals Council received additional evidence and heard argument. (AR 641-46.) On May 1, 2009, it issued a decision, finding that Plaintiff was disabled from December 10, 1998 to September 15, 2000, but that she was not entitled to benefits because she had not timely filed her application, i.e., within 12 months of the date her disability ended (September 15, 2000).*fn1 (AR 12-13.) Plaintiff then commenced the instant action.
The ALJ's Failure to Discuss the Opinions of the Consultative and Treating Doctors That Were Rendered After Plaintiff's Date Last Insured Was Harmless Error Plaintiff contends that the ALJ erred by failing to address a December 11, 2002 opinion of consultative orthopedist Bunsri Sophon and a January 23, 2002 opinion of treating doctor William Mouradian. (Joint Stip. at 4-7, 17-19.) For the following reasons, the Court concludes that the ALJ erred when he failed to discuss these opinions but that the error was harmless.*fn2
The ALJ found that Plaintiff's condition improved on September 2, 2000, and that she was able to perform substantial gainful activity from that date forward.*fn3 (AR 38.) In doing so, he relied on, among other things, the testimony of medical expert Dr. Mason, who found that Plaintiff's condition did not meet a Listed impairment after September 1, 2000, and that she thereafter had the residual functional capacity to perform light work, with some restrictions. (AR 42, 43, 670-74, 677.) Dr. Mason testified that Plaintiff could do semi-sedentary work on a full-time basis, "where she could sit and stand and not be required to either do heavy lifting or any lifting of any significance." (AR 677.) He determined that Plaintiff could occasionally lift 20 pounds and frequently lift ten pounds; could stand, walk, or sit for six hours in an eight-hour workday, but should be given a sit or stand option; could only occasionally climb ramps and stairs, balance, stoop, kneel, crouch, crawl, and reach overhead; and would be precluded from climbing ladders, ropes, and scaffolds. (AR 673.)
The ALJ cited to other medical evidence in his decision, including a May 2, 2000 opinion of orthopedic surgeon Isaac Schmidt, who examined Plaintiff and determined that her arms and hands showed intact sensations, deep tendon reflexes, and muscle strength, with no signs of atrophy. (AR 42, 133.) The ALJ noted a September 15, 2000 MRI of Plaintiff's cervical spine, which showed bridging across the endplates in the spines with no recurrent disc protrusion, spinal stenosis, or foraminal narrowing. (AR 42, 405-06.) He also noted August 7, 2001 diagnostic studies of Plaintiff's lumbar spine, which showed nothing more than minimal degenerative disc disease at L2-L3. (AR 43, 383-84.) In addition, the ALJ noted the October 15, 2001 opinion of treating physician Dr. Mouradian, who found that Plaintiff was totally temporarily disabled in April 2000, but that, since December 2000, she had been "doing fairly well" performing home exercises, walking, and riding her mountain bike on surface streets. (AR 377.) Dr. Mouradian noted that range of motion and leg strength had improved, although Plaintiff continued to complain of some low back pain and episodic numbness. (AR 378.) After examining Plaintiff, he concluded that her forward flexion and extension were improved, her left shoulder range of motion was now full, and that "there are no significant upper extremity findings." (AR 378.) Dr. Mouradian determined that Plaintiff's orthopedic condition was permanent and stationary, and pronounced her "ready to be discharged from further treatment in this office." (AR 378.) He concluded that Plaintiff was limited to light work "in a standing or walking position, with a minimum of demands for physical effort." (AR 379.)
The ALJ adopted Dr. Mason's residual functional capacity findings. (AR 43.) Based on these limitations, a vocational expert testified that Plaintiff could not perform her past work, but could perform work as a cashier, general office clerk, and assembler, which were jobs that, even with erosion because of Plaintiff's need for a sit/stand option, existed in significant numbers in the local and national economies. (AR 679-80.)
Plaintiff now contends that the ALJ's failure to consider the December 11, 2002 opinion of consultative examiner Dr. Sophon constitutes reversible error. She points out that Dr. Sophon determined that she would be limited to only occasional reaching (not just overhead reaching, as the ALJ concluded), which would preclude her from doing the jobs identified by the vocational expert. (Joint Stip. at 5-6; AR 264.) Plaintiff argues that, even though Dr. Sophon's evaluation was made after the expiration of her insured status, his findings were still relevant to the issue of whether she was disabled before her date last insured ...
