Lymphocyte Mitogen Response Assays

Lymphocyte mitogen response assays are covered by Medicare when medically necessary to assess lymphocytic function in diagnosed immunodeficiency diseases or to monitor immunotherapy. The test is explicitly not covered for monitoring cancer treatment because that use is considered experimental. The policy does not specify documentation requirements or frequency limits.
