What can this data not tell us?
- Billing data and prescribing data come from different CMS files. Neither one measures clinical outcomes, and neither one tells you whether this doctor is in a specific plan's network.
- Part D records do not report current medication use, plan coverage, price, pharmacy availability, or plan-directory status.
- Where CMS withholds a count for privacy, we show that note instead of a number. A withheld count is not zero.
- CMS billing data does not list Medicare Advantage plan-directory status for this doctor.
- CMS service and prescribing records are historical public-use aggregates; they do not report current appointment availability, clinical outcomes, or patient-specific medical advice.
- Part D provider-and-drug records do not include current formulary status, copay amount, pharmacy price, prior-authorization rules, or step-therapy rules.
What should you verify separately?
Verify plan-directory status, drug formulary rules, pharmacy pricing, appointment availability, and clinical questions against current plan documents and the relevant provider or care team.
