L42 - Pityriasis rosea - a common, temporary skin rash with pink, scaly patches
International Classification of Diseases
What is a ICD-10 Code?
ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.
Detailed Description
Pityriasis rosea is a common, harmless skin condition that causes a distinctive rash. It typically begins with a single, larger patch (called a 'herald patch') followed by smaller pink or salmon-colored, oval-shaped patches with fine scales. The rash often appears in a Christmas tree pattern on the back and chest. This condition is temporary and usually resolves on its own within 6-12 weeks without treatment. While the exact cause is unknown, it's believed to be triggered by a viral infection and is not contagious once the rash appears.
Additional Information
