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).

HEATHER KRANTZ, MD appears in the CMS NPPES registry as a Obstetrics & Gynecology Physician provider holding MD credentials at 900 OLD ROSWELL LAKES PKWY STE 310, ROSWELL, GA, 30076, with a listed phone of (434) 248-7508. NPI 1184674327 was issued on 05/10/2006.

Medicare Part D records for calendar year 2023 show 71 prescription claims written by this provider, covering 14 Medicare beneficiaries and totaling roughly $4K in drug spend, split 51% brand-name and 49% generic by claim count.

Obstetrics & Gynecology Physician is a mid-sized specialty nationwide, with 44,313 enrolled providers across 56 states and an average of 179 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
