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).

CAIYUN LIAO, MD, MPH is a Reproductive Endocrinology Physician provider practicing in WORCESTER, Massachusetts, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD, MPH. NPI: 1982066379. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

CAIYUN LIAO, MD, MPH appears in the CMS NPPES registry as a Reproductive Endocrinology Physician provider holding MD, MPH credentials at 119 BELMONT STREET, WORCESTER, MA, 01605, with a listed phone of (508) 334-8706. NPI 1982066379 was issued on 03/24/2016.

Medicare Part D records for calendar year 2023 show 24 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $772 in drug spend. 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.

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.
