Robert Gatewood, D.D.S., M.S., PERIOD appears in the CMS NPPES registry as a Periodontics provider holding D.D.S., M.S., PERIOD credentials at 222 EAST CHALAN SANTO PAPA, Hagatna, GU, 96910, with a listed phone of (671) 477-2379. NPI 1912216128 was issued on 10/05/2010.

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 Periodontics providers operate outside Part D entirely.

Periodontics is a mid-sized specialty nationwide, with 6,062 enrolled providers across 53 states and an average of 264 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
