ICD-10 Code H47.629 – Disorders of Visual Cortex in (Due to) Inflammatory Disorders, Unspecified Side of Brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.629 – Disorders of visual cortex in (due to) inflammatory disorders, unspecified side of brain
What it is
This code identifies a visual cortex disorder caused by an inflammatory condition, when the affected side of the brain is not specified. Use it for documented cortical visual problems linked to inflammation.
Clinical signs
Findings may include impaired visual processing, visual field loss, or difficulty recognizing visual information despite normal eye structures. Clinical features vary; refer to documentation.
When to use this code
Use H47.629 when the provider documents a disorder of the visual cortex due to inflammation and does not name the right or left side. It is appropriate when the record ties the visual deficit to a cerebral inflammatory process. If the cause or laterality is unclear, check documentation.
Do not use for
Do not use this code for primary eye disease, retinal disorders, or nonspecific vision loss without a documented cortical inflammatory cause. Do not assign it if the side of the brain is specified and another code is required.
Coding tip
Confirm both the inflammatory cause and the unspecified laterality before coding H47.629.
