About H31.0
H31.0 is the ICD-10-CM diagnosis code for chorioretinal scars. 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 (other disorders of choroid), H31.0 is specifically for chorioretinal scars. Related codes cover choroidal degeneration (H31.1), hereditary choroidal dystrophy (H31.2), choroidal hemorrhage and rupture (H31.3), choroidal detachment (H31.4), other specified disorders of choroid (H31.8) and unspecified disorder of choroid (H31.9).
To report this condition, pick the subcode that matches the documentation: H31.00 (scars), H31.01 ((post-traumatic)), H31.02 (retinopathy) and H31.09 (scars).
The conditions in its Excludes2 note aren't part of H31.0, but may be coded alongside it if the patient has both: postsurgical chorioretinal scars (H59.81-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
