SABA AHMED appears in the CMS NPPES registry as a Rheumatology Physician provider at 5841 S MARYLAND AVE, CHICAGO, IL, 60637, with a listed phone of (888) 824-0200. NPI 1861448003 was issued on 05/26/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AHMED most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 2,330 prescription claims written by this provider, covering 398 Medicare beneficiaries and totaling roughly $659K in drug spend, with an opioid prescribing rate of 15.5%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 97.7188/100 for the 2023 performance year (Quality 75.4375), compared with the national average of 83.1.

Rheumatology Physician is a mid-sized specialty nationwide, with 6,181 enrolled providers across 52 states and an average of 2,054 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
