CHRISTOPHER HADDOCK, ACNP-BC appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding ACNP-BC credentials at 27 PARK ST, HYANNIS, MA, 02601, with a listed phone of (508) 862-5976. NPI 1619283496 was issued on 08/31/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HADDOCK 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 421 prescription claims written by this provider, covering 169 Medicare beneficiaries and totaling roughly $30K in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 7.6%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 100/100 for the 2023 performance year, compared with the national average of 83.1.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
