ERIN MARRIOTT, RN, CPNP, APNP appears in the CMS NPPES registry as a Pediatric Nurse Practitioner provider holding RN, CPNP, APNP credentials at 7974 UW HEALTH CT, MIDDLETON, WI, 53562, with a listed phone of (608) 890-8051. NPI 1629038898 was issued on 03/23/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARRIOTT 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 22 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $818 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.

Pediatric Nurse Practitioner is a mid-sized specialty nationwide, with 21,082 enrolled providers across 52 states and an average of 312 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.
