Sirivan Seng, M.D. appears in the CMS NPPES registry as a Physician Nutrition Specialist (Surgery) provider holding M.D. credentials at 10012 KENNERLY RD STE 406, Saint Louis, MO, 63128, with a listed phone of (314) 525-1224. NPI 1487184859 was issued on 06/18/2017.

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 Physician Nutrition Specialist (Surgery) providers operate outside Part D entirely.

Physician Nutrition Specialist (Surgery) is a narrow specialty nationwide, with 2 enrolled providers across 2 states and an average of 28 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
