HAORAN PENG, MD, PHD appears in the CMS NPPES registry as a Gastroenterology Physician provider holding MD, PHD credentials at 302 POINT NORTH PL, DALTON, GA, 30720, with a listed phone of (706) 272-4127. NPI 1851745061 was issued on 04/14/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PENG 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 226 prescription claims written by this provider, covering 134 Medicare beneficiaries and totaling roughly $541K in drug spend, split 30% brand-name and 70% generic by claim count. 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 80.8933/100 for the 2023 performance year (Quality 94.8661, Cost 43.156), compared with the national average of 83.1.

Gastroenterology Physician is a mid-sized specialty nationwide, with 16,567 enrolled providers across 54 states and an average of 833 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
