H31.09Other chorioretinal scars

H31.09 is the ICD-10-CM diagnosis code for other 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 H31.0, choose H31.09 (Other chorioretinal scars) only when documentation doesn't support a more specific option: unspecified chorioretinal scars (H31.00), macula scars of posterior pole (postinflammatory) (post-traumatic) (H31.01) and solar retinopathy (H31.02).

To report this condition, pick the subcode that matches the documentation: H31.091 (right eye), H31.092 (left eye), H31.093 (bilateral) and H31.099 (unspecified eye).

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