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).

DINESH SINGH, MD is a Urology Physician provider practicing in DERBY, Connecticut, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1346225638.

DINESH SINGH, MD appears in the CMS NPPES registry as a Urology Physician provider holding MD credentials at 300 SEYMOUR AVE STE 202, DERBY, CT, 06418, with a listed phone of (203) 732-2651. NPI 1346225638 was issued on 12/09/2005.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
