ICD-10 Code L71 – Rosacea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L71 – Rosacea
What it is
L71 identifies rosacea, a chronic inflammatory skin disorder that mainly affects the central face. It is used when documentation supports this diagnosis, not a temporary facial rash.
Clinical signs
Typical findings include facial redness, flushing, visible small blood vessels, papules, or pustules. Clinical features vary; refer to documentation.
When to use this code
Use L71 when the provider documents rosacea, including erythematous or papulopustular facial disease. Code it when the condition is confirmed in the assessment or problem list. If the note only describes nonspecific facial irritation, check documentation before assigning L71.
Do not use for
Do not use L71 for acne, seborrheic dermatitis, or simple transient flushing without a rosacea diagnosis. Check documentation if the facial eruption is not clearly identified.
Coding tip
Match the code to the exact rosacea type only when the record clearly states it; otherwise, use the unspecified code and query if needed.
