Cystoid macular edema following cataract surgery, bilateral

This code signifies the presence of cystoid macular edema (CME) affecting both eyes, which has developed as a complication following cataract extraction surgery. CME is characterized by fluid accumulation in the macula, leading to retinal swelling and impaired central vision.

Apply this code when documentation clearly indicates bilateral cystoid macular edema occurring after a patient has undergone cataract surgery. The physician's notes should explicitly link the CME to the prior surgical intervention and confirm its presence in both eyes.

• Ensure the documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Confirm the CME is a post-procedural complication of cataract surgery, not due to other etiologies.
• Sequence this code after the primary diagnosis if the CME is a secondary condition impacting the patient's overall care.
