Mojan Deriss, PA-C appears in the CMS NPPES registry as a Behavior Analyst provider holding PA-C credentials at 32144 AGOURA RD STE 106, Westlake Village, CA, 91361, with a listed phone of (805) 379-3376. NPI 1740740372 was issued on 03/20/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Deriss 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 383 prescription claims written by this provider, covering 190 Medicare beneficiaries and totaling roughly $140K in drug spend, split 11% brand-name and 89% generic by claim count. 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.

Behavior Analyst is a high-volume specialty nationwide, with 96,225 enrolled providers across 55 states and an average of 663 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.
