GARY HAAS, D.O. appears in the CMS NPPES registry as a Interventional Pain Medicine Physician provider holding D.O. credentials at 1119 HIGHLAND AVE STE 11, CLARKSTON, WA, 99403, with a listed phone of (509) 780-4450. NPI 1912917618 was issued on 08/08/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HAAS 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 155 prescription claims written by this provider, covering 89 Medicare beneficiaries and totaling roughly $4K in drug spend, with an opioid prescribing rate of 32.9%. 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.

Interventional Pain Medicine Physician is a narrow specialty nationwide, with 1,528 enrolled providers across 53 states and an average of 2,197 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.
