Small plaque parapsoriasis

This code identifies a chronic, inflammatory skin condition characterized by multiple, small (typically less than 5 cm), reddish-brown, scaly patches that are often asymptomatic. It is considered a benign variant within the spectrum of parapsoriasis, distinct from large plaque parapsoriasis which carries a higher risk of progression.

Apply this code for patients diagnosed with small plaque parapsoriasis based on clinical presentation and, often, histopathological confirmation. Documentation should clearly describe the characteristic small, persistent, erythematous, and slightly scaly patches without significant epidermal atrophy or poikiloderma.

• Differentiate carefully from large plaque parapsoriasis, which has a different code and prognostic implications.
• Ensure documentation specifies "small plaque" to support this specific diagnosis.
• Do not confuse with common psoriasis, which presents with thicker, silvery scales and different distribution patterns.
