ICD-10 Code H43.821 – Vitreomacular adhesion, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.821 – Vitreomacular adhesion, right eye
What it is
Vitreomacular adhesion means the vitreous remains attached to the macula in the right eye. It describes an anatomic finding that can be incidental or associated with visual disturbance.
Clinical signs
Clinical features vary; refer to documentation. Findings may include persistent vitreoretinal attachment at the macula on ocular imaging, sometimes with metamorphopsia or blurred central vision.
When to use this code
Use H43.821 when the provider documents vitreomacular adhesion in the right eye, with or without symptoms. It is appropriate when imaging or examination confirms the condition and the right eye is specified. Check documentation if the note also describes traction, detachment, or another retinal disorder.
Do not use for
Do not use this code for left eye or bilateral vitreomacular adhesion, or when the record only says vitreous degeneration without macular attachment. If the documentation is unclear, check documentation.
Coding tip
Always code the eye laterality exactly as documented and confirm whether the finding is adhesion alone or part of vitreomacular traction.
