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.
Medical records must be made available to the Contractor upon request to substantiate coverage and payment.

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.
Coverage requires documentation that the immune globulin therapy is reasonable and necessary in accordance with LCD L34007 and applicable NCDs.
Molecular syndromic infectious disease panels are covered when billed with the appropriate proprietary CPT® or PLA code and an accompanying ICD-10-CM diagnosis that documents medical necessity in the patient record.
FDA-cleared/approved molecular infectious disease tests performed consistent with their intended use are covered without a DEX Z-code when billed with an appropriate supporting ICD-10-CM code.
A panel is a single test (single unit of service UOS=1) and is covered as one service even if it reports multiple pathogens or targets.
