GUILLERMO KATIGBAK, MD appears in the CMS NPPES registry as a Personal Emergency Response Attendant provider holding MD credentials at 267 GRANT ST, BRIDGEPORT, CT, 06610, with a listed phone of (203) 384-4490. NPI 1487674602 was issued on 07/20/2006.

Medicare Part D records for calendar year 2023 show 148 prescription claims written by this provider, covering 80 Medicare beneficiaries and totaling roughly $5K in drug spend, with an opioid prescribing rate of 16.9%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 81.5328/100 for the 2023 performance year (Quality 71.9687, Cost 54.3854), compared with the national average of 83.1.

Personal Emergency Response Attendant is a narrow specialty nationwide, with 830 enrolled providers across 48 states and an average of 996 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.
