Stephen Kales appears in the CMS NPPES registry as a Occupational Medicine Physician provider at 1493 CAMBRIDGE ST, Cambridge, MA, 02139, with a listed phone of (617) 665-1580. NPI 1437218542 was issued on 12/06/2006.

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 Occupational Medicine Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 86.3/100 for the 2023 performance year (Quality 78.8, Cost 58.7), compared with the national average of 83.1.

Occupational Medicine Physician is a narrow specialty nationwide, with 2,230 enrolled providers across 52 states and an average of 605 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
