Sept. 2023 Bulletin – Laboratory/Pathology Non-Specific ICD-9-CM Codes Update

Effective for dates of service on or after April 1, 2022, the following non-specific ICD-10-CM diagnosis codes Exclusion have been removed from all laboratory/pathology codes: Z00.01, Z01.01, Z01.020, Z01.021, Z01.110, Z01.118, Z01.12, Z01.812, Z01.84, Z02.0, Z02.2 and Z02.89.

An Erroneous Payment Correction (EPC) will be implemented to reprocess denied claims with dates of service on or after the effective date of this billing policy, that were appropriately submitted based on the guidance published in this article, but erroneously denied because Medi-Cal had not yet implemented the system changes to support appropriate adjudication.
