Medicare prescribing
What this provider billed to Medicare Part D in 2024, as CMS published it. Medicare Part D only: what they prescribed outside it is not here.
- 10,435
- Claims
- Prescriptions and refills billed to Part D, as CMS counts them.
- $1,210,224
- Total drug cost
- What Part D, the plan and the patient paid together. Not what this provider was paid — they are paid nothing out of it.
- 927
- Beneficiaries
- People with at least one prescription from this provider.
- 2,042
- Brand-name claims
- Of the claims above, those for a brand-name drug.
- 8,248
- Generic claims
- Of the claims above, those for a generic.
- not reported
- Opioid claims
- Claims for an opioid. CMS published no figure for this provider, and there is no suppression marker on this measure — so this is an absent figure rather than a withheld one, and it is not a zero.
- 153
- Antibiotic claims
- Claims for an antibiotic.
- Nurse Practitioner
- Prescriber type
- As CMS classifies this prescriber.
A blank is not a zero. CMS withholds a value between 1 and 10, and withholds the next lowest alongside it so the first cannot be worked out by subtraction — so a withheld figure is not even evidence that the number was small. Rows for ten or fewer claims are removed from the file altogether, which is why the parts of a total can be withheld while the total is published.
