Choroidal dystrophy (central areolar) (peripapillary)

This code describes a group of inherited or acquired progressive degenerative conditions affecting the choroid, the vascular layer of the eye. These dystrophies lead to atrophy of the choroid and retinal pigment epithelium, often resulting in vision impairment. The specific types covered include central areolar, generalized, and peripapillary choroidal dystrophies.

Use this code when documentation specifies a diagnosis of choroidal dystrophy, particularly when the type is identified as central areolar, generalized, or peripapillary. This code is appropriate for patients presenting with progressive vision loss attributed to these specific choroidal degenerations. Supporting documentation should include ophthalmological examination findings, such as funduscopic reports detailing choroidal atrophy.

• Ensure the documentation specifies one of the included types (central areolar, generalized, or peripapillary) to accurately assign this code.
• Distinguish from other retinal or choroidal degenerations that may have similar presentations but different underlying etiologies and specific codes.
• Code any associated visual impairment or blindness separately, if documented, using the appropriate codes from Chapter 7.
