Other disorders of choroid (H31)
The ICD-10 codes in the H31 category are used to identify various other disorders of the choroid, a layer of the eye important for vision. These codes cover a wide range of conditions, including different types of chorioretinal scars, choroidal degeneration, hereditary dystrophies, hemorrhages, ruptures, detachments, and neovascular disorders.
This section helps medical coders specify diagnoses such as chorioretinal scars (including unilateral, bilateral, or unspecified eyes), commonly called disseminated scars or retinal scars. It also includes macula scars following inflammation or trauma, and solar retinopathy, a retinal light damage condition sometimes referred to as retinal light toxicity. The codes cover various forms of choroidal degeneration, whether age-related (or senile atrophy) or diffuse secondary atrophy affecting one or both eyes. Hereditary conditions like choroideremia, central areolar choroidal dystrophy, or gyrate atrophy are distinctly categorized. Codes for choroidal hemorrhage, expulsive hemorrhage, and rupture assist in documenting traumatic or spontaneous bleeding events. Detachments of the choroid, including serous or hemorrhagic types, have specific codes, helping clarify severity and eye affected. Lastly, other specified disorders like polypoidal choroidal vasculopathy and idiopathic choroidal folds are included. These detailed codes guide accurate documentation and treatment planning related to complex choroidal conditions.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Choroid
The thin, highly vascular membrane covering most of the posterior of the eye between the RETINA and SCLERA.
Choroideremia
An X chromosome-linked abnormality characterized by atrophy of the choroid and degeneration of the retinal pigment epithelium causing night blindness.
Gyrate Atrophy
Progressive, autosomal recessive, diffuse atrophy of the choroid, pigment epithelium, and sensory retina that begins in childhood.
Polypoidal Choroidal Vasculopathy
A CHOROID neovascularization characterized by serosanguineous retinal pigment epithelial detachment and leakage of serous exudate sometimes associated with aneurysmal polypoidal lesions.
Uveal Effusion Syndrome
Rare disease characterized by suprachoroidal fluid accumulation between the CHOROID and the SCLERA, annular detachment of the CHOROID, often with secondary RETINAL DETACHMENT; OPTIC DISK EDEMA, and minimal signs of UVEITIS and INTRAOCULAR PRESSURE changes.
