To describe the usage patterns of pharmacological treatments for neovascular age-related macular degeneration (AMD) in Medicare fee-for-service beneficiaries. Retrospective review of all Medicare fee-for-service Part B claims for neovascular AMD during 2008. Medicare beneficiaries having undergone treatment were identified. The data collected for each visit for a given beneficiary included age, race, gender, Medicare region, state/zip code of residence, date of visit, whether or not the beneficiary had a treatment, the type and amount of drug, and dollars paid by Medicare. The main outcome measures were the number and rate of treatments, the types of drugs used for treatment, and the payments for these drugs. Of the 222 886 unique beneficiaries, 146 276 (64.4%) received bevacizumab and 80 929 (35.6%) received ranibizumab. A total of 824 525 injections were performed with 480 025 injections of bevacizumab (58%) and 336 898 injections of ranibizumab (41%). National rates of injections per 100 000 fee-for-service Part B Medicare beneficiaries for bevacizumab and ranibizumab were 1506 and 1057, respectively. Total payments by Medicare were $20 290 952 for bevacizumab and $536 642 693 for ranibizumab. In 39 out of 50 states, the rate of injection was higher for bevacizumab compared with ranibizumab. In 2008, bevacizumab was used at a higher rate than ranibizumab for the treatment of neovascular AMD. Even though bevacizumab accounted for 58% of all injections, Medicare paid $516 million more for ranibizumab than bevacizumab. These data suggest that despite its off-label designation, intravitreal bevacizumab is currently the standard-of-care treatment for neovascular AMD in the United States. Published by Elsevier Inc.
