ICD-10 Code H31.01 – Macula scars of posterior pole (postinflammatory) (post-traumatic) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.01 – Macula scars of posterior pole (postinflammatory) (post-traumatic)
What it is
This code identifies a scar involving the macula or posterior pole of the eye after inflammation or trauma. It reflects residual damage in the central retina, where vision is most affected.
Clinical signs
Patients may have reduced central vision, distorted vision, or a central blind spot. Funduscopic findings typically show a visible scar or pigmentary change in the macular area; clinical features vary, refer to documentation.
When to use this code
Use H31.01 when the provider documents a macular scar of the posterior pole and links it to prior inflammation or injury. Code the condition when it is the active documented diagnosis, not just a remote history. If the record does not clearly state the cause, check documentation.
Do not use for
Do not use this code for nonspecific retinal scarring without macular or posterior pole involvement. Do not apply it when the chart describes only active inflammation, trauma, or another retinal disorder without a documented scar.
Coding tip
Confirm that the note specifies both location and cause; H31.01 is for a scar, not the underlying inflammatory or traumatic event.
