L71: ICD10 Code for Rosacea

L71 refers to Rosacea, a group of dermatologic and cosmetic conditions affecting hair, nails, sebaceous glands, or sweat glands. These disorders vary widely, from common acne to rare hair shaft abnormalities, and require targeted evaluation and care.

Symptoms

• Hair loss – Patchy (L63), patterned (L64), or scarring (L66)
• Nail changes – Discoloration, thickening, or deformities in L60–L62
• Pustules and papules – Common in acne (L70) and rosacea (L71)
• Facial flushing or thickening – Specific to rosacea (L71)
• Visible cysts – Noted in L72 follicular cysts
• Excessive or abnormal sweating – Linked to L74 or L75

Diagnosis

Diagnosis of Rosacea is clinical, often supported by dermoscopy, microscopy, cultures, or biopsy. Trichoscopy and scalp assessment aid hair loss evaluations, while lab testing may identify hormonal or autoimmune contributors.
