What This Guide Covers

This guide helps Virginia patients with Humana coverage get Busulfex (busulfan injection) approved for hematopoietic stem cell transplant conditioning. We'll walk through forms, timelines, and appeal options specific to Humana's process in Virginia.

Who this helps:

  • CML patients preparing for allogeneic transplant
  • Transplant centers navigating Humana's PA requirements
  • Patients facing denials who need appeal guidance
  • Caregivers managing the authorization process

Quick outcome preview: With complete documentation and proper submission, most Busulfex requests for FDA-approved transplant conditioning are approved within 15 days. Denials often stem from incomplete clinical records or missing TKI failure documentation.

At Counterforce Health, we help patients, clinicians, and specialty pharmacies turn insurance denials into targeted, evidence-backed appeals. Our platform analyzes denial letters and plan policies to draft point-by-point rebuttals that align with each payer's specific requirements.


Before You Start: Plan Type and Benefits

Verify Your Humana Plan Type

Medicare Advantage vs. Commercial: Your appeal rights and timelines differ significantly.

  • Humana Medicare Advantage: Follow federal Medicare appeal rules (not Virginia's state external review)
  • Humana commercial plans: May use Virginia's external review process after internal appeals

Check your insurance card or call Humana Member Services to confirm your exact plan type.

Confirm Medical vs. Pharmacy Benefit

Busulfex for transplant conditioning is covered under your medical benefit (Part B equivalent), not pharmacy benefit. This means:

  • Billed through hospital/clinic with HCPCS code J0594
  • Requires medical prior authorization, not standard pharmacy PA
  • Subject to medical benefit deductibles and coinsurance

Verify Network Status

Ensure your transplant center is in-network with your Humana plan. Out-of-network transplants face higher cost-sharing and additional authorization hurdles.

What to Ask During Follow-Up Calls

Sample Script for Provider Staff: "I'm calling to check the status of a prior authorization for Busulfex (busulfan injection) for [patient name], member ID [number]. The request was submitted on [date] for transplant conditioning. Can you provide the current status and expected decision timeline?"

Document Everything:

If Your Request is Denied

Understanding Your Appeal Rights

Medicare Advantage Members:

  • Level 1: Reconsideration by Humana (65 days to file)
  • Level 2: Independent Review Entity (automatic if partially denied)
  • Level 3: Administrative Law Judge hearing
  • Appeals follow federal Medicare rules, not Virginia's state external review

Commercial Plan Members:

First-Level Appeal Strategy

Submit Within Deadlines: Don't miss the 60-65 day window for Medicare Advantage or plan-specific deadlines for commercial coverage

Strengthen Your Case:

  • Address specific denial reasons point-by-point
  • Include additional clinical evidence
  • Request peer-to-peer review with Humana medical director
  • Cite relevant sections of Humana's medical policy

Sample Appeal Opening: "We respectfully request reconsideration of the denial for Busulfex (busulfan injection) prior authorization for [patient name]. This medication is FDA-approved for conditioning prior to allogeneic hematopoietic stem cell transplantation in CML patients, which directly matches our patient's clinical scenario."

From our advocates: We've seen transplant-related appeals succeed when providers include a detailed timeline showing how delays in conditioning could impact transplant scheduling and donor coordination. Medical directors understand the urgency of transplant protocols and often approve on peer-to-peer review when the clinical picture is clear.

Renewal and Re-Authorization

When to Seek Renewal

Busulfex authorizations are typically single-use for one conditioning course. Re-authorization is rarely needed unless:

  • Transplant is delayed and authorization expires
  • Additional conditioning cycles are required
  • Complications necessitate modified protocols

Documentation for Renewals

If Transplant is Delayed:

  • Updated medical necessity letter
  • Confirmation that patient remains transplant candidate
  • Revised transplant timeline
  • Current organ function assessments

For Modified Protocols:

  • Rationale for protocol changes
  • Updated dosing calculations
  • New risk assessments
  • Transplant team recommendations
