About coding choroid degeneration

The ICD-10-CM code for choroid degeneration is H31.10 (Unspecified choroidal degeneration).

Within H31.1, choose H31.10 (Unspecified choroidal degeneration) only when documentation doesn't support a more specific option: age-related choroidal atrophy (H31.11) and diffuse secondary atrophy of choroid (H31.12).

To report this condition, pick the subcode that matches the documentation: H31.101 (eye), H31.102 (eye), H31.103 (bilateral) and H31.109 (eye).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
