December 2016 Texas Medicaid Provider Procedures Manual

Radiology and Laboratory Services Handbook : 2 Independent Laboratory : 2.2 Services, Benefits, Limitations, and Prior Authorization : 2.2.7 Complete Blood Count (CBC)

A CBC and its components may be reimbursed by Texas Medicaid without prior authorization. The medical necessity for all laboratory services must be documented in the client’s medical record, and the services must be referenced to an appropriate diagnosis code.
Texas Medicaid considers a baseline CBC appropriate for the evaluation and management of existing and suspected disease processes. CBC tests should be individualized and based on client history, clinical indications, or proposed therapy, and will not be reimbursed for screening purposes.
When related CBC procedure codes are billed for the same date of service by the same provider, the first procedure code will be reimbursed and all other procedure codes will be denied.
Reticulocyte procedure codes may be reimbursed in addition to the CBC, hemogram, differential analysis, and platelet procedure codes indicated above.
Refer to:
The appropriate Texas Medicaid fee schedule on the TMHP website at for CBC procedure codes that may be reimbursed.
