H31.21 is a billable ICD code used to specify a diagnosis of choroideremia. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code H312 is used to code Choroideremia

Choroideremia /kɒˌrɔɪdᵻˈriːmi.ə/ (CHD) is a rare X-linked recessive inherited disorder giving rise to retinal disease and eventual blindness, resulting from degeneration of the choriocapillaris of the choroid and of the retinal pigment epithelium of the retina. The disease results in progressive loss of vision, almost exclusively in males; in childhood, night blindness is the most common first symptom.[not verified in body] As the disease progresses, vision loss results, frequently starting as an irregular ring that gradually expands both in toward central vision and out toward the extreme periphery; progression continues throughout the individual's life, where both the rate of change and the degree of visual loss are variable among those affected, even within the same family.[not verified in body]
