ICD-10: L73.9

The ICD-10 code L73.9 refers to "Follicular disorder, unspecified." This classification falls under the broader category of follicular disorders, which are conditions affecting hair follicles. Below is a detailed overview of this diagnosis, including its clinical description, potential causes, symptoms, and treatment options.

Clinical Description

Follicular disorders encompass a range of conditions that primarily affect the hair follicles, which are small organs in the skin from which hair grows. The term "unspecified" in L73.9 indicates that the specific type of follicular disorder has not been clearly defined or diagnosed. This can include various conditions that may present with similar symptoms but do not fit neatly into more specific categories.
