DARRELL AREVALO appears in the CMS NPPES registry as a Family Nurse Practitioner provider at 700 E OGDEN AVE STE 202, WESTMONT, IL, 60559, with a listed phone of (630) 789-9785. NPI 1417444373 was issued on 04/17/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AREVALO 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 12,652 prescription claims written by this provider, covering 384 Medicare beneficiaries and totaling roughly $453K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 0.3%. 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 12.4409/100 for the 2023 performance year (Quality 0, Cost 41.4695), compared with the national average of 83.1.

Family Nurse Practitioner is a high-volume specialty nationwide, with 209,817 enrolled providers across 56 states and an average of 1,222 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
