TERRI GROSSHANS, PA-C appears in the CMS NPPES registry as a Massage Therapist provider holding PA-C credentials at 3909 9TH AVE SW, OLYMPIA, WA, 98502, with a listed phone of (360) 570-3460. NPI 1790904613 was issued on 04/25/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GROSSHANS 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 992 prescription claims written by this provider, covering 333 Medicare beneficiaries and totaling roughly $15K in drug spend, with an opioid prescribing rate of 20.6%. 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.

Massage Therapist is a high-volume specialty nationwide, with 68,402 enrolled providers across 55 states and an average of 853 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.
