Other and unspecified pityriasis

This code represents various forms of pityriasis that are not specifically classified elsewhere, or when the specific type of pityriasis is not documented. Pityriasis is a group of skin conditions characterized by fine scales, often with associated inflammation or discoloration. This category captures less common or ill-defined presentations of these dermatoses.

Use this code when documentation indicates a diagnosis of pityriasis without specifying a particular type, such as pityriasis rosea or pityriasis versicolor. It is appropriate for conditions like pityriasis alba or other atypical presentations. The medical record should clearly state "pityriasis, unspecified" or describe a form of pityriasis not covered by more specific ICD-9-CM codes.

• Avoid using this code if a more specific type of pityriasis (e.g., pityriasis rosea, pityriasis versicolor) is documented; use the appropriate specific code instead.
• Query the provider for clarification if "pityriasis" is documented without further detail, to determine if a more precise diagnosis can be assigned.
• Consider associated symptoms or body sites if documented, as these might point to a more specific diagnosis.
