Coverage Summary

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

This policy covers intravenous immune globulin (IVIG) products (multiple brand formulations listed) for FDA‑approved and compendia‑recommended indications including primary immunodeficiencies, immune thrombocytopenia (ITP), chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain‑Barré syndrome (GBS), myasthenia gravis exacerbations, dermatomyositis/polymyositis, transplant‑related uses, CAR‑T and immune checkpoint inhibitor toxicities, and other specified immune and hematologic conditions. The policy lists covered products and HCPCS/NDC mappings and a broad Appendix of covered ICD‑10 diagnosis codes.

Prior authorization (PA) is required; initial PA validity varies by indication (1, 2, 3, or 6 months or through delivery for FAIT) with indication‑specific renewal rules. Baseline safety labs (BUN and serum creatinine) must be obtained within 30 days of request, and renewal requires BUN/creatinine within the last 6 months. The policy provides indication‑specific dosing ranges and regimens (examples: PID 200–800 mg/kg q21–28d, CIDP load 2 g/kg then maintenance 1 g/kg q21d, ITP 2 g/kg or 1 g/kg x2, GBS 2 g/kg over 5 days, FAIT 1 g/kg weekly until delivery), guidance for adjusted body weight dosing when BMI ≥ 30 kg/m2 or actual weight ≥ 20% above IBW, and recommendations to reduce dose to the lowest effective amount with periodic trial of dose reduction or discontinuation except where noted (e.g., PID).

Authorization and billing guidance include per‑indication maximum billable HCPCS units and per‑day limits (examples: PID billable units = 180 per 21 days; CIDP load = 460 units over 5 days, maintenance = 230 units per 21 days; Guillain‑Barré = 460 units over 5 days for up to two courses), use of HCPCS/J‑codes and the generic 90283 where applicable, and requirement to submit one of the listed ICD‑10 covered diagnosis codes to support medical necessity.

Evidence of infections / diagnostic testing

Provide diagnostic evidence supporting the requested indication; include copies of relevant testing and prior records with the request.

Documented history of prior infections where required (e.g., recurrent sinopulmonary infections, deep-seated infections, IV antibiotic courses)
Electrodiagnostic testing reports for neuropathies (e.g., nerve conduction studies showing demyelination, conduction block, prolonged latencies)
Cerebrospinal fluid (CSF) analysis when required for diagnosis (e.g., Guillain-Barré syndrome)
Muscle biopsy reports when required to support diagnoses such as dermatomyositis or polymyositis

Billing Rule

Adhere to max HCPCS units per indication

Adhere to maximum HCPCS units per indication when billing. Ensure units billed per dose and per time period do not exceed the policy "Maximum Units" for the specific diagnosis.

Examples: CIDP loading 460 units (per policy) with maintenance 230 units; ITP 460 units (per dose) for specified number of days; FAIT 230 units per dose (per policy)
Other indication limits include Kawasaki's Disease 460 units (2 doses only), Multifocal Motor Neuropathy 460 units, and various transplant/supportive care limits as listed in the Maximum Units section
Reference the policy "Maximum Units" section for the full per-indication unit and days limits before submitting claims

Documentation Required

Renewal safety labs

For renewal/continuation requests, provide recent safety laboratory results and document any infusion adjustments.

BUN and serum creatinine within the last 6 months must be provided for renewal requests
If renal function has declined or other safety issues arise, document infusion rate adjustments or other management steps taken

Documentation Required

Objective response documentation for renewals

Document objective clinical response for renewal approvals. Provide measurable evidence of continued benefit compared to baseline.

Validated functional or strength scales (e.g., INCAT score, Medical Research Council [MRC] muscle strength grading, 6-minute walk test)
Relevant laboratory markers where applicable (e.g., platelet counts for ITP)
Documented physical exam findings demonstrating clinical improvement or stabilization compared with baseline

Billing Rule

Report HCPCS/90283 variants

Report the appropriate HCPCS and J-code variants when billing IVIG and related administration products; follow local payer mapping guidance where applicable.

Common codes: 90283 (immue globulin, diagnostic/administration-related), J1572, J1459, J1576, J1599
Confirm local/mapped code variants with payer billing instructions or local Medicare MAC guidance prior to claim submission

Documentation Required

Use covered ICD-10 diagnosis codes

Claims must include a covered ICD-10 diagnosis code that corresponds to an approved indication. Follow applicable Medicare NCDs, LCDs, and LCAs where they apply.

Ensure the claim includes one of the policy-listed ICD-10 diagnosis codes supporting medical necessity
When treating Medicare patients, observe relevant MAC jurisdiction coverage determinations (NCD/LCD/LCA) that may affect coverage and coding

Documentation Required

Reference Medicare coverage resources

Refer to CMS resources and the Medicare Administrative Contractor jurisdiction for additional coverage and coding guidance when applicable.

Use the CMS Coverage Database (https://www.cms.gov/medicare-coverage-database) to locate Medicare NCDs and LCDs relevant to IVIG indications
Check the applicable MAC jurisdiction for local coverage determinations that may alter coverage, documentation, or billing requirements

CMS Guidance & Medicare Part B

Medicare Part B coverage for outpatient IVIG is governed by the Medicare Benefit Policy Manual (Pub.100‑2), Chapter 15, §50 and may be limited by National Coverage Determinations (NCDs) and Local Coverage Determinations/Articles (LCDs/LCAs). The policy references the NCD for Intravenous Immune Globulin for Autoimmune Mucocutaneous Blistering Diseases (NCD 250.3) and notes that multiple contractor‑specific LCDs/LCAs exist providing billing and coding guidance for IVIG.

The document lists examples of jurisdiction‑specific NCD/LCD/LCA references and contractors (e.g., A57187, A54660, A54641, A54643, A57194, A54662, A56786, A56718, A57778, A57160) and identifies MAC jurisdictions (Noridian, Novitas, Palmetto GBA, First Coast, WPS, NGS, CGS). Providers processing Medicare (Part B) claims should consult the CMS Coverage Database and applicable contractor LCD/LCA documents for jurisdictional rules and billing instructions.

Background

Scope: This policy applies to intravenous immune globulin (IVIG) products (multiple brands listed) used for FDA‑approved and compendia‑recommended indications. It enumerates specific products and formulations, maps HCPCS and NDC codes to products, and covers a wide range of immune, neurologic, hematologic, transplant, and immunotherapy‑related indications.

Intent and practical guidance: the policy defines prior authorization and medical necessity criteria by indication, specifies baseline and renewal laboratory and diagnostic documentation requirements, provides dosing regimens and rules for adjusted body weight dosing, sets limits on maximum HCPCS units per dose and per time period, and includes billing instructions (use of HCPCS/J‑codes and 90283 mapping). It also includes recommendations to taper to the lowest effective dose and to document objective clinical response for renewals.

PA = Prior authorization: utilization management requirement to obtain approval before IVIG administration per indication‑specific rules and initial validity periods.

IgG = Immunoglobulin G: the key laboratory marker used for eligibility and monitoring (e.g., thresholds such as 200 mg/dL or 400 mg/dL appear in criteria).

CIDP = Chronic Inflammatory Demyelinating Polyneuropathy: an indication requiring electrodiagnostic evidence of demyelination plus clinical criteria and prior trial/intolerance of corticosteroids.

AIDP = Acute inflammatory demyelinating polyneuropathy (Guillain‑Barré type): acute neuropathy indication with specific timing, severity, reflex, and CSF diagnostic criteria.
