HCPCS code G0452 (molecular pathology procedure; physician interpretation and report) is used to report a medically necessary interpretation and written report of a molecular pathology test, above and beyond the report of laboratory results. It has come to our attention that certain genetic laboratories are encouraging primary care providers to utilize this code when reviewing the submitted molecular laboratory results. However, this is not the purpose of this code. It is intended to be used by more specialized providers, such as pathologists, molecular pathologists or geneticists, who process the samples, interpret the results, and create a written report. The review of the test results is considered to be part of the medical decision-making key component and is not separately billable.
