The medical record must document that the testing is expected to influence treatment of the condition for which the test is ordered and include an ordering physician/NPP requisition containing the relevant ICD-10-CM diagnosis code.
Ordering physician/NPP documentation should include history and physical or exam findings, problems/diagnoses, and relevant data (e.g., lab tests, imaging) that support medical necessity.
Performing laboratories must retain accreditation, test requisition, test records/procedures, preliminary and final reports, and quality control records and provide them when requested.
For laboratory-developed tests (LDTs)/protocols, documentation must include the diagnostic test/assay, lab/manufacturer, comparable assays (if relevant), assay description, analytical validity, clinical validity, and clinical utility.

When a molecular panel of 5–50 genes is ordered, bill the appropriate panel CPT code (81445, 81449, 81450, or 81451) instead of submitting individual single-gene CPT codes.
When 51 or more genes are ordered for molecular biomarkers, bill the appropriate large-panel CPT code (81455 or 81456) rather than individual gene codes.
When a panel contains more than one but fewer than five genes, use the corresponding existing panel CPT code or CPT 81479 (unlisted molecular pathology procedure) if no specific panel CPT exists.
Use modifier 91 only when a test is performed more than once on the same day for the same patient and the repeat testing is necessary to obtain multiple results in the course of treatment.
CPT 88182 reports the physician professional and facility technical components of DNA ploidy and S-phase analysis of tumor by flow cytometry.
CPT 88184 (first marker) and CPT 88185 (each additional marker) report the facility technical component of flow cytometric immunophenotyping for assessment of potential hematolymphoid neoplasia.
