HCPCS code J7507: Oral tacrolimus, immediate release, per 1 mg2026 Medicare rate & RVUs in Guam

CMS doesn’t publish an office rate for J7507 in Guam.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What J7507 covers

This code identifies oral tacrolimus in its immediate-release formulation, an immunosuppressive medicine used in transplant care to help prevent rejection. Transplant clinicians prescribe and manage this therapy; the dispensing supplier reports the drug for a covered Medicare benefit. It is distinct from extended-release oral tacrolimus, injectable tacrolimus, and tacrolimus granules prepared for oral suspension.

CMS assigns J7507 physician fee schedule status E, so it is excluded from the physician fee schedule. When Medicare covers the item, it pays under another payment method. For a covered Part B drug, the HCPCS pricing method generally uses CMS’s quarterly Average Sales Price (ASP) drug pricing files; special Medicare coverage instructions apply. Each unit represents 1 mg of tacrolimus, so the unit count corresponds to the milligrams represented by the drug billed.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
