How Sleep Medicine (Internal Medicine) Physician compares to other specialties among Texas providers
MIPS score not measured
CMS assigned a neutral 75/100 threshold
CMS did not publish any Quality, Cost, Promoting Interoperability, or Improvement Activities category score for this clinician. This administrative threshold is not comparable with the national average of clinicians whose MIPS score was measured.
How MIPS and board certification work
The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).
Stanley Wang, M.D. J.D. M.P.H. appears in the CMS NPPES registry as a Sleep Medicine (Internal Medicine) Physician provider holding M.D. J.D. M.P.H. credentials at 2559 WESTERN TRAILS BLVD, Austin, TX, 78745, with a listed phone of (512) 899-2028. NPI 1962592071 was issued on 10/13/2006.
Medicare Part D records for calendar year 2023 show 8,293 prescription claims written by this provider, covering 1,088 Medicare beneficiaries and totaling roughly $1.6 million in drug spend, split 16% brand-name and 84% generic by claim count. On the CMS Merit-based Incentive Payment System, this provider carries a Final Score of 75/100 for the 2023 performance year, but CMS published no Quality, Promoting Interoperability, Improvement Activity or Cost score: this is the neutral performance threshold CMS assigns where nothing was scored, so it is not comparable with clinicians whose score was measured.
Sleep Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 859 enrolled providers across 52 states and an average of 1,310 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist, always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.

- Check the active license and any disciplinary history with the Texas medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Sleep Medicine (Internal Medicine) Physician peer on Medicare volume and prescribing patterns. Compare providers
