In simple words: This refers to a hereditary condition affecting the back of the eye, specifically the choroid. It can impact vision depending on the area and extent of the damage.

This code specifies a dystrophy of the choroid, the vascular layer of the eye lying between the retina and the sclera.The condition can manifest in several locations:central (around the macula), areolar (in a ring-like pattern), generalized (widespread), or peripapillary (surrounding the optic nerve).

Example 1: A patient presents with progressive central vision loss. Fundus photography reveals changes consistent with central areolar choroidal dystrophy., A routine eye exam in a patient with a family history of choroidal dystrophy reveals peripapillary atrophy, diagnosed as peripapillary choroidal dystrophy., A patient with generalized choroidal dystrophy is monitored over time for disease progression and receives counseling about potential vision changes.

Documentation should include details from ophthalmological examination, including funduscopic findings and potentially results of imaging studies like fundus photography or optical coherence tomography (OCT). Family history of similar conditions should be noted.

** This code does not specify laterality.If applicable, the diagnosis does not have laterality and codes for both eyes should be submitted.Fundus photography is a covered service with this diagnosis for many payers.
