TIFFANY MORRIS, RN, MSN, FNP-C appears in the CMS NPPES registry as a Critical Care Medicine Registered Nurse provider holding RN, MSN, FNP-C credentials at 2700 GRANT ST, CONCORD, CA, 94520, with a listed phone of (925) 674-2880. NPI 1497158802 was issued on 09/30/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MORRIS 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 592 prescription claims written by this provider, covering 427 Medicare beneficiaries and totaling roughly $50K in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 8.6%. 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.

Critical Care Medicine Registered Nurse is a mid-sized specialty nationwide, with 6,529 enrolled providers across 53 states and an average of 752 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.
