Medical Billing in Texas: The Short Version

Texas runs one of the largest Medicaid managed care programs in the country, with most beneficiaries enrolled through STAR, STAR+PLUS, STAR Kids, or CHIP plans rather than fee-for-service. Claims route through TMHP (Texas Medicaid & Healthcare Partnership), and the state's 95-day timely filing window is among the shortest for any Medicaid program. On the commercial side, Blue Cross Blue Shield of Texas (an HCSC plan) is the dominant payer statewide, with heavy Medicare Advantage penetration in the major metros.

Texas Billing Realities to Know

STAR Program Complexity

STAR, STAR+PLUS, STAR Kids, and STAR Health each have distinct enrollment, authorization, and billing rules. A patient’s program assignment determines which MCO portal and PA list applies.

TMPPM Compliance

The Texas Medicaid Provider Procedures Manual (TMPPM) is updated monthly. Fee schedules, benefit limitations, and modifier rules change often enough that stale references cause denials.

95-Day Filing Window

The short Medicaid filing window means eligibility or claim errors discovered late are often unrecoverable. Front-end verification matters more in Texas than in most states.

No State Income Tax, High MA Growth

Texas metros are among the fastest-growing Medicare Advantage markets — payer mix in a typical practice is shifting toward MA plans with prior-auth-heavy workflows.
