David Clauss, O.D. appears in the CMS NPPES registry as a Corneal and Contact Management Optometrist provider holding O.D. credentials at 1870 RESERVOIR ST, Harrisonburg, VA, 22801, with a listed phone of (540) 434-6622. NPI 1225112147 was issued on 10/25/2006.

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 Corneal and Contact Management Optometrist providers operate outside Part D entirely.

Corneal and Contact Management Optometrist is a narrow specialty nationwide, with 1,548 enrolled providers across 52 states and an average of 235 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
