Date: February 7, 2025

Attention: All Providers

Call to action: Texas Children’s Health Plan (TCHP) would like to inform providers that a correction has been made to the Texas Medicaid & Healthcare Partnership (TMHP)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.

Next step for providers: Providers should share this communication with their staff.
