Documentation Required
- This billing and coding article provides guidelines that complement Local Coverage Determination L34415 for CT of the abdomen and pelvis; consult LCD L34415 for specific coverage indications, limitations, and documentation requirements.
- Medical records must document the indication(s) supporting use of IVIG for each claim.
- For indications where routine IVIG use is not indicated, the medical record must document prior interventions that were unsuccessful or reasons those interventions were not tolerated.
- Documentation must support objective clinical response to IVIG for continued coverage.
Key Coverage Criteria
- IVIG is covered only for indications specified as covered in the related Local Coverage Determination (LCD) and when medical necessity criteria in that LCD are met.
- Pharmacogenomics (PGx) testing is covered when it is reasonable and necessary per LCD L39063 and Medicare coverage rules for the beneficiary's clinical indication.
- CPT 81418 (PGx multi-gene panel) is covered when the test assays at least 6 genes, including CYP2C19 and CYP2D6 and CYP2D6 duplication/deletion analysis, and the panel is clinically indicated to guide drug therapy.
- A clinician-ordered single gene or allele test is considered covered when the billed component corresponds to the single gene/allele that was reasonable and necessary, even if the laboratory platform concurrently interrogated other genes operationally.
- Germline testing panels that include some previously tested genetic content may be covered if there is established clinical utility for the remaining non-duplicative genetic components of the panel.
- Genes may be assayed serially or in parallel; additional gene analyses done after a reflex decision are covered when those reflexive analyses are reasonable and necessary for the beneficiary's care.
