H31.8
ICD-10-CMThis code represents various uncommon or ill-defined conditions affecting the choroid that are not classified elsewhere. These disorders involve the vascular layer of the eye, situated between the retina and the sclera, and can impact vision due to their role in nourishing the outer retina.
Use this code when documentation specifies a choroidal disorder that doesn't fit more specific ICD-10-CM codes for choroidal detachment, hemorrhage, rupture, or degeneration. Examples include idiopathic choroidal neovascularization not associated with macular degeneration, or other rare, non-specific choroidal pathologies. The physician's notes should clearly describe the choroidal involvement and rule out more specific diagnoses.
