30-day fills

4,743 standardized 30-day fills in 2024

8 years (graduated 2018)

May accept Medicare assignment

CMS data show this clinician may accept Medicare assignment. Clinicians who do not always accept assignment can decide case by case.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

Guide: What Medicare assignment means

No telehealth indicator

CMS shows this indicator only when recent Medicare claims include telehealth services. The clinician may still offer telehealth; ask the office.
