CMS National Coverage Policy
Title XVIII of the Social Security Act (SSA), §1862(a)(1)(A), states that no Medicare payment shall be made for items or services that “are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member.”
42 Code of Federal Regulations (CFR) §410.32 Diagnostic x-ray tests, diagnostic laboratory tests, and other diagnostic tests: Conditions.
Coverage Indications, Limitations, and/or Medical Necessity
Indications and Limitations of Coverage
This policy provides limited coverage for HLA-B*15:02 genotype testing when the following criteria are met:
- Patient is of Asian and Oceanian ancestry; AND
- Initial treatment with carbamazepine, phenytoin or fosphenytoin is planned
Background
In 2004, researchers reported individuals with the HLA-B*1502 had an increased risk to develop Stevens-Johnson syndrome (SIS) or toxic epidermal necrolysis (TEN) when exposed to carbamazepine2. SJS and TEN, considered two variants of a disease continuum, are severe, sometimes lethal diseases of the skin and mucous membranes. A third, intermediate condition is called SJS/TEN. The most serious cases result in separation of the epidermis from the dermis in large sheets, which can also lead to infection. Sloughing can also occur in the bronchial, gastrointestinal and ocular epithelia.
Estimates indicate 10-15% of the population from China, Thailand, Malaysia, Indonesia, the Philippines, and Taiwan carry the HLA-B*1502 allele. South Asians, including Indians, appear to have an intermediate chance of having HLA-B*1502, averaging 2 to 4%, but it is higher in some subgroups. Oceanians also have an increased incidence of HLA-B *1502 serotype. The incidence of the HLA-B*1502 serotype in the European Caucasian population has been reported at less than 0.1% 1, in the African population as 0.2% and in the Native American and Hispanic populations as 0% 3.
In 2007, the FDA issued a black box label warning for carbamazepine stating, “Patients with ancestry in genetically at-risk populations should be screened for the presence of HLA-B*1502 prior to initiating treatment.” More recent evidence has supported the FDA recommendations 4 and at least one study has demonstrated that prospective screening of HLA-B*1502 has reduced the incidence of SJS/TEN in a Chinese population 5.
