Unspecified disease of hair and hair follicles

This code represents a general or unspecified disorder affecting the hair and/or hair follicles. It indicates a pathological condition of the pilosebaceous unit where the specific nature or cause of the disease has not been identified or documented. This could include various forms of alopecia, hirsutism, or other hair shaft abnormalities without a definitive diagnosis.

Use this code when the medical record indicates a disease of the hair or hair follicles, but the physician's documentation does not specify a more precise diagnosis. This is appropriate for initial encounters where further diagnostic workup is pending, or when the provider explicitly states "unspecified hair disorder." Documentation supporting this code would typically include symptoms like hair loss, abnormal hair growth, or scalp lesions without a definitive etiological diagnosis.

• Avoid using this code if a more specific ICD-9-CM code for a hair or follicle disorder is available and supported by documentation.
• Query the provider for clarification if a more specific diagnosis is suspected but not explicitly stated.
• This code should be used sparingly, primarily when no other information is available to assign a more precise code.
