About H31.10
H31.10 is the ICD-10-CM diagnosis code for unspecified choroidal degeneration. It belongs to category H31 (other disorders of choroid), block H30-H36 (disorders of choroid and retina) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
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.
