JOHN MAYENO, MD appears in the CMS NPPES registry as a Plastic Surgery within the Head & Neck (Otolaryngology) Physician provider holding MD credentials at 13652 CANTARA ST, PANORAMA CITY, CA, 91402, with a listed phone of (818) 375-2000. NPI 1609943828 was issued on 11/30/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MAYENO 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 273 prescription claims written by this provider, covering 110 Medicare beneficiaries and totaling roughly $6K in drug spend, with an opioid prescribing rate of 7.7%. 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.

Plastic Surgery within the Head & Neck (Otolaryngology) Physician is a narrow specialty nationwide, with 608 enrolled providers across 48 states and an average of 379 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
