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).

ANN MARIE GRUS, PTA appears in the CMS NPPES registry as a Physical Therapy Assistant provider holding PTA credentials at 1650 COCHRANE CIR, FORT CARSON, CO, 80913, with a listed phone of (719) 526-7120. NPI 1336684364 was issued on 12/29/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GRUS 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Physical Therapy Assistant providers operate outside Part D entirely.

Physical Therapy Assistant is a high-volume specialty nationwide, with 60,025 enrolled providers across 55 states and an average of 704 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.
