Coverage is limited to the FDA‑approved indication for GPP; all other uses are considered investigational. Authorization durations specified in the policy are 1 month for treatment of a GPP flare (short-course) and 12 months for maintenance treatment when not experiencing a flare. The coverage stance for spesolimab in this policy is covered_with_criteria. Key supporting sources include the Spevigo package insert (October 2025) and primary clinical trials such as the Trial of spesolimab for GPP (N Engl J Med. 2021;385(26):2431-2440).
Initial Therapy Criteria
FDA-Approved Indication
Covered when ALL of the following are met:
ALL of the following

History
- Relapsing or persistent: Member has a known documented history of GPP (either relapsing [greater than 1 episode] or persistent [greater than 3 months]).
- Recurrent flares: Member has had a history of at least two moderate-to-severe GPP flares (e.g., at least 5% body surface area is covered with erythema and the presence of pustules; GPPPGA total score >= 3).>= 3 for GPPPGA; >= 5% BSA
- History while on treatment (example): Member has had flaring while on concomitant treatment (e.g., retinoids, methotrexate, cyclosporine).
Listed as an example of history; policy language groups this with history criteria under initial section.
- Current status: Member currently has clear to almost clear skin.

- Maintenance continuation: For GPP when not experiencing a flare: Members must achieve or maintain a positive clinical response as evidenced by low disease activity or improvement in signs and symptoms of the condition.
- Documentation for continuation: Chart notes or medical record documentation supporting positive clinical response must be provided for continuation requests.
Unproven / Exclusions & Therapy Restrictions
Concomitant Therapy and TB Screening Requirements
ALL of the following
- Concomitant therapy restriction: Member cannot use spesolimab concomitantly with any other biologic drug or targeted synthetic drug for the same indication.
Claims may be denied if used concurrently.
- TB screening recency: Member must have a documented negative TB test (TST or IGRA) within 12 months of initiating therapy if biologic/targeted-synthetic naïve.within 12 months
- TB positive follow-up: If TB screening is positive, further testing (e.g., chest x-ray) is required to exclude active disease; do not administer medication to members with active TB infection; latent TB must be treated before initiation.
Operational: exclude active TB and treat latent TB prior to initiation.
