About coding choroid atrophy
The ICD-10-CM code for choroid atrophy is H31.10 (Unspecified choroidal degeneration). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H31.10.
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.
