Cystoid macular edema following cataract surgery, unsp eye

This code signifies the development of fluid accumulation within the macula, forming cysts, as a complication occurring after a patient has undergone cataract extraction surgery. This condition leads to blurred or distorted central vision due to swelling in the most sensitive part of the retina.

Use this code when the medical record clearly documents cystoid macular edema (CME) as a sequela of a prior cataract surgery, and the specific eye affected is not specified. Documentation should confirm the diagnosis of CME and its direct causal link to the preceding cataract procedure.

• Ensure documentation explicitly links the CME to a previous cataract surgery, not a concurrent or unrelated event.
• If the affected eye (right or left) is specified, use the more specific codes H59.031 (right eye) or H59.032 (left eye).
• This code is a post-procedural complication; consider sequencing it after the primary diagnosis if the CME is not the main reason for the encounter.
