Correction to Cytogenetics Testing Diagnosis Codes in 2024 ICD-10 Special Bulletin

Last updated on

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.

This is a correction to the 2024 International Classification of Diseases, Tenth Edition (ICD-10) Special Bulletin for cytogenetics testing for Texas Medicaid and the Children with Special Health Care Needs (CSHCN) Services Program.

The Cytogenetics Testing table incorrectly listed C2388 as an added diagnosis code. The correct diagnosis code is Q2388.
