Botox Spasticity denied for missing prior authorization by Humana?

Humana's specific coverage criteria for botox spasticity are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why Humana Requires Prior Authorization for OnabotulinumtoxinA (Botox) for Spasticity — and What to Do When It Is Denied

Humana requires prior authorization (PA) for onabotulinumtoxinA (Botox) before coverage is approved for spasticity. A denial at the PA stage — or a failure to obtain PA before treatment, resulting in a retrospective denial — means Humana has determined that the submitted clinical information does not satisfy the criteria in its coverage policy, or that required steps were skipped in the authorization workflow. This is the gateway denial: everything else (formulary, quantity, step therapy) is secondary to clearing this hurdle.

PA denials are highly appealable, particularly when the initial submission was incomplete. Resubmission with comprehensive documentation — structured to answer every policy criterion — succeeds in a significant proportion of cases.

## Federal Appeal Framework

ACA §2719 requires non-grandfathered plans to provide internal appeal and independent external review. ERISA §503 applies to self-funded employer plans. The external review window is approximately four months from the final internal denial. For patients with active functional impairment or rapid deterioration, request expedited review — Humana must decide within 72 hours and, for prospective treatment, within 72 hours of the request.

## Concrete Appeal Steps and Timeline

1. Obtain the PA denial letter and Humana's published prior-authorization criteria for botulinum toxin in spasticity. These criteria are the exact checklist your appeal must satisfy. 2. File the Level 1 internal appeal within the deadline on the denial notice. Do not miss this deadline — it preserves your right to external review. 3. If Level 1 is denied, file Level 2 or proceed to IRO external review. 4. If treatment is urgently needed, file an expedited appeal simultaneously with or in lieu of the standard track. 5. For ACA marketplace plans, request a summary of the specific criteria that were not met — you are entitled to this information.

## Documentation to Gather

• Diagnosis confirmation: specialist notes confirming the neurological condition (stroke, MS, cerebral palsy, TBI, spinal cord injury, etc.), affected limbs, and spasticity severity
• Prior treatment history with dates and outcomes: records of oral antispasticity agents tried (names, duration, outcome), physical and occupational therapy, and any prior botulinum toxin injections
• Clinical severity per the chart: spasticity scale assessments, functional limitation documentation, pain scores, and caregiver-burden notes
• Injection planning details: the prescribing physiatrist's or neurologist's plan identifying target muscle groups
• Prescriber medical-necessity letter written to directly address each of Humana's PA criteria — not a generic note

## Criteria-Mapping Structure

Retrieve Humana's PA criteria for Botox in spasticity. Map each requirement to a chart document:

| Humana PA Criterion | Supporting Documentation | |---|---| | Confirmed underlying neurological diagnosis | [Specialist note, ICD-10 code, date] | | Specific limb and muscle groups identified | [Injection plan or exam finding] | | Prior conservative/pharmacologic treatment documented | [Medication list with dates and outcomes] | | Functional impairment or pain severity documented | [Spasticity scale score + functional note] | | Qualified specialist prescribing and administering | [Provider credentials and specialty] | | Prescriber attestation of medical necessity | [Letter date] |

Submit the mapping table in the body of the appeal letter so the clinical reviewer can confirm compliance with each criterion without searching attachments.
