MARTHA HAGAMAN, M.D. appears in the CMS NPPES registry as a Pediatric Sleep Medicine Physician provider holding M.D. credentials at 4323 CAROTHERS PKWY STE 309, FRANKLIN, TN, 37067, with a listed phone of (615) 435-7720. NPI 1700069861 was issued on 12/12/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HAGAMAN 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 134 prescription claims written by this provider, covering 22 Medicare beneficiaries and totaling roughly $329K in drug spend, split 28% brand-name and 72% 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.

Pediatric Sleep Medicine Physician is a narrow specialty nationwide, with 99 enrolled providers across 30 states and an average of 357 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.
