What J7521 covers
J7521 identifies tacrolimus supplied as granules that are mixed to prepare an oral suspension. Tacrolimus is an immunosuppressant used to prevent organ rejection after transplantation. This formulation is distinct from immediate-release or extended-release oral tacrolimus products and from injectable tacrolimus. The code reports the granule suspension drug when it is furnished.
CMS excludes J7521 from the physician fee schedule under status E. When Medicare covers the drug, CMS classifies it as a Part B drug and generally pays from its quarterly ASP drug pricing files; special Medicare coverage instructions apply. Each HCPCS unit represents 0.1 mg of tacrolimus, so divide the furnished dose in milligrams by 0.1 to calculate units.
