MARY RIEGER, M.D. appears in the CMS NPPES registry as a Urogynecology and Reconstructive Pelvic Surgery (Obstetrics & Gynecology) Physician provider holding M.D. credentials at 911 W 38TH ST STE 202, AUSTIN, TX, 78705, with a listed phone of (512) 324-8670. NPI 1134548399 was issued on 04/15/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what RIEGER most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 775 prescription claims written by this provider, covering 211 Medicare beneficiaries and totaling roughly $154K in drug spend, with an opioid prescribing rate of 8.0%.

Urogynecology and Reconstructive Pelvic Surgery (Obstetrics & Gynecology) Physician is a narrow specialty nationwide, with 568 enrolled providers across 49 states and an average of 611 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
