If the denial is upheld, please provide in writing the specific clinical criteria used, the credentials of the reviewing clinician, and instructions for independent external review.

The controlling standard for ivig and immunoglobulin denials
Plans compare the diagnosis to their immunoglobulin policy, which typically lists FDA-labeled indications (primary immunodeficiency, immune thrombocytopenia, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, Kawasaki disease, and others) and selected off-label uses supported by published evidence. Medicare Part B covers immunoglobulin for primary immunodeficiency at home under 42 CFR 410.10 and the home IVIG benefit; other indications follow local coverage determinations in the Medicare Coverage Database. Plan criteria must be disclosed on request (29 CFR 2560.503-1(m)(8); 45 CFR 147.136).
What makes a ivig and immunoglobulin appeal letter win
Request the plan's immunoglobulin policy and the reviewer's specialty. Have the treating specialist write to each criterion: diagnosis with supporting labs or electrodiagnostic studies, prior therapies and results, measurable response to IVIG, and dosing rationale. For off-label uses, attach the guideline or peer-reviewed evidence the specialist relies on and identify it accurately. If the denial is 'experimental', the external review process specifically covers that determination (45 CFR 147.136(d)).
The letters that get overturned share a structure: they quote the denial, rebut the plan's specific criteria point by point, cite the controlling standard above, attach a treating-provider letter of medical necessity, and make a clear demand for reversal. Generic letters that simply ask the plan to reconsider do not move reviewers.
Documents to attach
- The denial letter naming the criterion or policy applied
- Specialist's notes with diagnosis, labs, and electrodiagnostic or imaging results
- Record of prior therapies and outcomes
- Infusion records showing dose, frequency, and documented response
- The plan's immunoglobulin policy (request it in writing)

Build my appeal free →IVIG and immunoglobulin appeal: frequently asked questions
my insurer says IVIG is experimental for my condition. Can that be appealed?
Yes. 'Experimental or investigational' determinations are appealable internally and are expressly within the scope of external review. The strongest appeals identify the published guideline or evidence the specialist relies on and show it directly.
My infusions are scheduled this week. What do I do first?
Ask for an expedited appeal in writing and have the prescriber confirm that delay could seriously jeopardize health. Expedited decisions are due within 72 hours.
my insurer approved IVIG before. Why is it denied now?
Continuation reviews look for measurable response. If the record only says 'doing well', the plan may treat that as no evidence. The specialist's note should record the objective measures the policy asks for.
Does my insurer have to tell me which policy it used?
For employer and ACA plans, yes: the internal rule, guideline, or protocol relied on must be provided free on request. Ask for it by name in the appeal.
