John Schruefer, MD appears in the CMS NPPES registry as a Phlebology Physician provider holding MD credentials at 9420 KEY WEST AVE, Rockville, MD, 20850, with a listed phone of (630) 725-2730. NPI 1003875808 was issued on 03/21/2006.

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 Phlebology Physician providers operate outside Part D entirely.

Phlebology Physician is a narrow specialty nationwide, with 275 enrolled providers across 43 states and an average of 463 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
