How Geriatric Medicine (Internal Medicine) Physician compares to other specialties among New Jersey providers
MIPS score not measured
CMS assigned a neutral 75/100 threshold
CMS did not publish any Quality, Cost, Promoting Interoperability, or Improvement Activities category score for this clinician. This administrative threshold is not comparable with the national average of clinicians whose MIPS score was measured.
How MIPS and board certification work
The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).
Ismet Mirza, M.D. appears in the CMS NPPES registry as a Geriatric Medicine (Internal Medicine) Physician provider holding M.D. credentials at 5 SANIBEL CT, Monroe, NJ, 08831, with a listed phone of (609) 619-3091. NPI 1538363841 was issued on 06/12/2007.
Medicare Part D records for calendar year 2023 show 9,232 prescription claims written by this provider, covering 311 Medicare beneficiaries and totaling roughly $509K in drug spend, split 12% brand-name and 87% generic by claim count, with an opioid prescribing rate of 1.8%. On the CMS Merit-based Incentive Payment System, this provider carries a Final Score of 75/100 for the 2023 performance year, but CMS published no Quality, Promoting Interoperability, Improvement Activity or Cost score: this is the neutral performance threshold CMS assigns where nothing was scored, so it is not comparable with clinicians whose score was measured.
Geriatric Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 4,171 enrolled providers across 52 states and an average of 4,450 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
