Infliximab Injection (Remicade)
What is this procedure?
Biologic TNF inhibitor used for rheumatoid arthritis, Crohn's disease, ulcerative colitis, psoriatic arthritis, and ankylosing spondylitis. Administered by IV infusion.
Does this require prior authorization?
Step Therapy / Pre-Requirements
Requires failure of conventional therapy. Many plans prefer biosimilar infliximab products over branded Remicade — may require biosimilar trial first.
Common Reasons This Gets Denied
Based on insurer policy analysis and claims data patterns. Frequency indicates how often this reason appears.
Infliximab prescribed for Crohn disease without documented induction with 5-ASA or corticosteroids first
TNF inhibitor therapy requires documented inadequate response to conventional induction therapy (5-ASA, corticosteroids).
How to prevent this
Document 8-week trial of 5-ASA (mesalamine) or corticosteroid induction with inadequate response before TNF inhibitor initiation.
Infliximab dosing increased beyond standard intervals (every 8 weeks) without documented loss of response on current schedule
Dose escalation justified only by documented clinical flare despite current dosing or loss of response.
How to prevent this
Confirm clinical flare with objective findings (elevated fecal calprotectin, endoscopy showing active inflammation) before dose increase authorization.

Medical Necessity Tips
What clinical evidence supports approval
- Document qualifying diagnosis with disease severity assessment
- Include failed conventional therapy documentation
- Note if biosimilar has been tried or provide rationale for branded product
- Provide treatment plan with dosing schedule
What to Do If Denied
If your infliximab injection (remicade) is denied, you have the right to appeal. Most denials are overturned on appeal when proper documentation is provided.
