ICD-10 Code H43.31 – Vitreous membranes and strands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.31 – Vitreous membranes and strands
What it is
H43.31 identifies vitreous membranes and strands, meaning fibrous or string-like material within the vitreous body of the eye. Use it when documentation specifically describes these vitreous changes.
Clinical signs
Patients may report floaters, blurred vision, or visual distortion, but findings can vary. Clinical features vary; refer to documentation and the ophthalmology exam for the exact vitreous abnormality described.
When to use this code
Use this code when the provider documents vitreous membranes, strands, or similar fibrous opacities in the vitreous cavity. It is appropriate when the note names this condition as the diagnosis or a confirmed exam finding. If the record only mentions nonspecific floaters, check documentation.
Do not use for
Do not use it for retinal disease, vitreous hemorrhage, or other eye findings unless vitreous membranes or strands are clearly documented. Do not assume the code from vague visual complaints alone.
Coding tip
Code from the ophthalmologist’s exact wording, and avoid substituting this code for general vitreous opacity or symptom-only documentation.
