Brian Johnson, FNP-C, CRNFA, MSN appears in the CMS NPPES registry as a Registered Nurse First Assistant provider holding FNP-C, CRNFA, MSN credentials at 21200 S LAGRANGE RD, Frankfort, IL, 60423, with a listed phone of (708) 256-0816. NPI 1124180708 was issued on 12/13/2006.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Registered Nurse First Assistant providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 95/100 for the 2023 performance year (Quality 80), compared with the national average of 83.1.

Registered Nurse First Assistant is a narrow specialty nationwide, with 2,649 enrolled providers across 50 states and an average of 419 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
