ICD-10 Code H31.012 – Macula scars of posterior pole (postinflammatory) (post-traumatic), left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.012 – Macula scars of posterior pole (postinflammatory) (post-traumatic), left eye
What it is
This code identifies a scar involving the macula or posterior pole of the left eye. It is used when the scar is described as postinflammatory or post-traumatic.
Clinical signs
Patients may have reduced central vision, distortion, or a visible retinal pigment change on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H31.012 when the provider documents a scar of the posterior pole or macula in the left eye and links it to prior inflammation or trauma. It is appropriate for chronic residual findings, not an active infection or acute injury. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for active inflammatory eye disease, fresh ocular trauma, or unspecified retinal scars. If the record does not confirm the left eye, verify the laterality before coding.
Coding tip
Code the documented cause and eye laterality exactly as stated; if either is missing, query the provider.
