Guttate psoriasis

This code represents guttate psoriasis, a distinct form of psoriasis characterized by small, teardrop-shaped, red, scaly lesions that typically appear suddenly over large areas of the body, often following a streptococcal infection. It is an acute, eruptive condition, usually affecting children and young adults.

This code is appropriate when documentation clearly indicates a diagnosis of guttate psoriasis. Common scenarios include patients presenting with a sudden onset of widespread, small, papular psoriatic lesions, especially after a recent upper respiratory infection. Physician notes should specify "guttate" to support this diagnosis.

• Differentiate from other forms of psoriasis (e.g., plaque psoriasis, inverse psoriasis) which have distinct ICD-10-CM codes.
• Consider coding an associated streptococcal infection (e.g., J02.0 for streptococcal pharyngitis) if documented as the precipitating factor.
• Ensure the documentation explicitly states "guttate psoriasis" rather than just "psoriasis" to avoid coding to a more general or unspecified code.
