Hair Loss ICD-10-CM Codes

What hair loss ICD codes can I use?

There’s a wide array of hair loss ICD codes you can use. A few specifically have hair loss in their names, and there are codes specific to Alopecia areata, a type of autoimmune disorder tied to hair loss. For this short guide, we will cover a bit of both:

1. L65.9 - Nonscarring hair loss, unspecified

This ICD-10 code is meant to be used on a patient confirmed to have nonscarring hair loss. In the context of this ICD-10 code, the site of the hair loss isn’t specified. What is meant by nonscarring hair loss is that the hair follicles are preserved, which means that hair loss can be reversed and regrowth is still possible.

2. L65.8 - Other specified nonscarring hair loss

This ICD-10 code is meant to be used on a patient confirmed to have nonscarring hair loss. This is only meant to be used if the person has nonscarring hair loss not covered by other ICD-10 codes.

3. L63.9 - Alopecia areata, unspecified

This ICD-10 code is meant for a patient confirmed to have Alopecia Areata, the autoimmune disorder we mentioned earlier. The unspecified label points to the specific nature of the disorder to be unknown. All that is known is that the patient has the disorder.

4. L63.0 - Alopecia (capitis) totalis

This ICD-10 code is meant to be used for a patient confirmed to have Alopecia Totalis. This type of Alopecia means that the person who has it is completely bald because it is characterized by the total loss of hair on the scalp.

5. L63.1 - Alopecia universalis

This ICD-10 code is meant to be used for a patient confirmed to have Alopecia Universalis. This type of Alopecia means that the person who has it is completely hairless. Yes, even your eyebrows, body hair, pubic hair, all the hair.

6. L66.9 - Cicatricial alopecia, unspecified

This ICD-10 code is meant to be used for a patient confirmed to have Cicatricial Alopecia. This is a scarring type of Alopecia, meaning the hair follicles are destroyed. This leads to scarring and permanent hair loss.

Are these hair loss ICD codes billable?

Yes. All the aforementioned ICD codes are valid and billable.

Clinical information about hair loss

Hair loss, or Alopecia, can result from many things, like inheriting Alopecia Areata, hormone changes, conditions that can affect hair, extreme stress, or aging.

Depending on the cause of the hair loss, it can either be temporary (meaning her regrowth is possible) or permanent (the hair follicles were destroyed, so hair regrowth becomes impossible). Treatment for hair loss will depend on the causes, so it’s best to test your patients first and find out the nature of their hair loss.
