ICD-10 Code L71.9 – Rosacea, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L71.9 – Rosacea, unspecified
What it is
L71.9 identifies rosacea when the record does not specify a subtype. It is used for a chronic facial skin disorder that commonly affects the central face.
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 this code when the provider documents rosacea without naming a subtype such as erythematotelangiectatic or papulopustular. It also fits cases where the note confirms rosacea but gives no further detail. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use L71.9 when a more specific rosacea subtype is documented. Do not assign it for other facial rashes, acne, or dermatitis unless the provider clearly states rosacea.
Coding tip
Query for subtype details when the diagnosis says only “rosacea,” because a more specific code may be available.
