DENIS GRILLO, D.O. appears in the CMS NPPES registry as a Otolaryngology/Facial Plastic Surgery Physician provider holding D.O. credentials at 790 SE 5TH TER, CRYSTAL RIVER, FL, 34429, with a listed phone of (352) 795-0011. NPI 1235127937 was issued on 10/07/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GRILLO 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 565 prescription claims written by this provider, covering 302 Medicare beneficiaries and totaling roughly $39K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 3.5%. 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 75/100 for the 2023 performance year, compared with the national average of 83.1.

Otolaryngology/Facial Plastic Surgery Physician is a narrow specialty nationwide, with 744 enrolled providers across 53 states and an average of 561 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
