Last updated on

The Texas Medicaid & Healthcare Partnership (TMHP) has identified the following errors in the Texas Medicaid Provider Procedures Manual (TMPPM), Medical and Nursing Specialists, Physicians, and Physician Assistants Handbook, subsection 9.2.43.1, “Testing of Polymorphic 2C19”:

  • The reference to code 2C9 is incorrect. The correct code is 2C19.
  • Procedure code 81227 is incorrect. The correct procedure code is 81225.

TMHP will correct these errors in the April TMPPM release.

Note: Texas Medicaid managed care organizations (MCOs) must provide all medically necessary, Medicaid-covered services to Medicaid members who are enrolled in their MCO. Administrative procedures, such as prior authorization, precertification, referrals, and claims and encounter data filing, may differ from traditional Medicaid (fee-for-service) and from MCO to MCO. Providers should contact the member’s specific MCO for details.
