Ophiasis

This code represents a specific pattern of alopecia areata characterized by hair loss that occurs in a band-like fashion around the periphery of the scalp, typically affecting the occipital, temporal, and parietal regions. It is a chronic autoimmune condition where the immune system attacks hair follicles, leading to non-scarring hair loss.

Use this code when documentation clearly specifies "ophiasis" or describes alopecia areata with the characteristic band-like pattern of hair loss around the scalp's circumference. Supporting documentation should include a physician's diagnosis based on clinical examination.

• Ensure the physician's documentation explicitly states "ophiasis" or describes the classic ophiatic pattern of alopecia areata.
• Do not confuse this with other patterns of alopecia areata (e.g., alopecia totalis, alopecia universalis) which have distinct codes.
• Code any associated conditions or complications, such as psychological distress, separately.
