Transplant and immunosuppressant denials
Solid-organ transplant patients depend on continuous immunosuppressive therapy to prevent rejection. UNOS/OPTN guidelines establish that immunosuppressant regimens generally cannot be switched without significant clinical risk. Denials of transplant evaluation, listing, surgery, or maintenance immunosuppression are among the most clinically urgent appeals.
What gets denied
- Transplant evaluation and waitlisting
- Transplant surgery (kidney, liver, heart, lung)
- Specific brand of immunosuppressant (tacrolimus, mycophenolate, sirolimus)
- Generic-to-brand switches denied
- Anti-rejection biologic therapy
- Out-of-network transplant centers
Common denial reasons
- Plan claims patient not medically eligible for transplant
- Step therapy on immunosuppressants
- Plan formulary forces switch from brand to generic
- Out-of-network transplant facility
- Post-transplant complications denied as unrelated
How we approach the appeal
Cite UNOS/OPTN clinical guidelines for transplant eligibility and continuity of care. For immunosuppressant switch denials, attach the treating transplant team's letter documenting the rejection risk from any regimen change. Many plans have specific transplant carve-out networks (Centers of Excellence) — confirm in-network status of the specific center before assuming OON. Medicare Part B covers immunosuppressants post-transplant under federal law.
Urgent appeals: 72 hours. Standard: 30 days for prior auth, 60-180 days filing window. Transplant cases routinely qualify for expedited urgent review.
