Psoriasis, unspecified

This code represents a general diagnosis of psoriasis without further specification of its type or manifestation. Psoriasis is a chronic autoimmune skin condition characterized by red, scaly patches, typically on the elbows, knees, scalp, and lower back.

Use this code when the medical record clearly indicates a diagnosis of psoriasis but lacks details regarding the specific type (e.g., plaque, guttate, inverse, pustular, erythrodermic). This code is appropriate when the provider's documentation simply states "psoriasis" without further elaboration.

• Avoid using this code if a more specific type of psoriasis is documented; always code to the highest level of specificity.
• Review documentation for any mention of associated conditions, such as psoriatic arthritis (L40.5x), which would require additional coding.
• If the provider documents "psoriasis" but also describes characteristics of a specific type, query the provider for clarification to ensure accurate coding.
