Other psoriasis

This code represents various forms of psoriasis that do not fit into more specific categories like pustular, erythrodermic, or arthropathic psoriasis. It encompasses presentations such as guttate, inverse, and plaque psoriasis when a more precise ICD-9-CM code is unavailable or not documented.

Use this code when the medical record clearly documents a diagnosis of psoriasis, but the specific type is not further elaborated or falls outside the descriptions of other defined psoriasis codes. This is appropriate for general or unspecified psoriasis diagnoses where the physician has not indicated a more distinct variant.

• Avoid using this code if a more specific psoriasis type (e.g., pustular, erythrodermic) is documented; always code to the highest level of specificity.
• Ensure documentation supports a diagnosis of psoriasis; do not use for other dermatological conditions.
• Consider if additional codes for manifestations (e.g., psoriatic arthritis) are also warranted, as this code only covers the skin condition.
