ICD-10 Code L94.4 – Gottron’s papules (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L94.4 – Gottron’s papules
What it is
L94.4 identifies Gottron’s papules, which are characteristic raised lesions over the knuckles and other extensor joints. They are classically associated with dermatomyositis.
Clinical signs
Look for violaceous or erythematous papules or plaques on the metacarpophalangeal and interphalangeal joints. Clinical features vary; refer to documentation for associated findings such as scalp, nailfold, or muscle involvement.
When to use this code
Use L94.4 when the record specifically documents Gottron’s papules as a diagnosis or finding. It is appropriate when the clinician identifies these lesions in the context of dermatomyositis or as a distinct cutaneous sign. If the note only says “rash” or “hand lesions,” check documentation.
Do not use for
Do not use this code for nonspecific dermatitis, eczema, or any papular rash without documentation of Gottron’s papules. Check documentation if the lesions are described only as hand swelling, arthritis, or another skin condition.
Coding tip
Code L94.4 only when the provider names Gottron’s papules; otherwise, query for clearer lesion documentation.
