    ICD-10-CM Code For Other Disorders Of Choroid: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H31 includes diagnoses for non-retinal choroidal disorders such as choroidal inflammation, degeneration, detachments, and other specified choroidal abnormalities that affect the vascular layer beneath the retina. These ICD-10-CM diagnosis codes are used to document clinical presentations involving choroidal involvement, complications that affect visual function, and to capture details of laterality, chronicity, or associated ocular findings. Accurate coding within the ICD-10-CM H31 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM H31: Other Disorders Of Choroid Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM H31) group for other disorders of choroid encompasses diagnoses affecting the choroid, the vascular layer of the eye beneath the retina. These conditions can impact vision through inflammation, degeneration, or structural abnormalities of the choroid and often involve the posterior segment of the eye. Accurate coding is important to reflect disease severity and guide appropriate reimbursement and clinical recordkeeping.

    When to Use

    Use a code from this group when the clinical documentation identifies a choroidal condition such as choroiditis, choroidal detachment, or other specified choroidal pathology. Select the most specific code that reflects laterality, acuity, and any documented complications to accurately represent the patient s condition.

    Typical Clinical Scenarios

    • An elderly patient presents to the ophthalmology clinic with progressive blurry vision and metamorphopsia in one eye over several months. Fundus exam shows patchy areas of chorioretinal atrophy and pigmentary changes consistent with chronic presumed ocular histoplasmosis-like choroidopathy; multimodal imaging (OCT, FA) confirms choroidal scarring without active neovascularization. A diagnosis from this group is assigned for chronic choroidal degenerative/scar changes. Typical codes: H31.101, H31.102
    • A middle-aged patient is seen urgently for sudden onset of floaters and photopsias after head trauma; dilated exam reveals a localized suprachoroidal hemorrhage with choroidal detachment and associated decreased visual acuity. Because the primary pathology involves acute choroidal disruption and hemorrhagic detachment, an acute choroidal disorder code from the group is used to capture the traumatic choroidal injury. Typical codes: H31.301, H31.309
    • A patient with long-standing posterior uveitis is followed for recurrent inflammation and now demonstrates multifocal choroiditis with active inflammatory lesions and secondary choroidal neovascular membrane causing vision loss. The encounter documents the inflammatory choroidal disease as a comorbidity complicating the uveitis and guiding ocular management, so a code reflecting focal or multifocal choroiditis is assigned. Typical codes: H31.011, H31.019
