The most appropriate diagnosis code must be indicated on the prior authorization request and on the claim.
Prior authorization is required for alglucosidase alfa and documentation must include all of the following:
Laboratory evidence of acid alpha-glucosidase (GAA) deficiency, (i.e., below the laboratory-defined cut-off value as determined by the laboratory performing the GAA enzyme activity assay). Tissues used for determination of GAA deficiency may include blood, muscle, or skin fibroblasts.
