Under Texas House Bill 300 (Tex. Health & Safety Code Chapter 181), the state-law definition of "covered entity" differs from the federal HIPAA definition primarily because it:
A. Is limited to hospitals and physician practices licensed by the Texas Medical Board
B. Extends to any person who assembles, collects, analyzes, uses, evaluates, stores, or transmits protected health information, regardless of whether they are a health plan, provider, or clearinghouse
C. Only applies to entities that bill Medicare or Medicaid for services rendered in Texas
D. Excludes business associates, unlike the federal definition
