ICD-10 Code H59 – Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59 – Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified
What it is
H59 covers eye or adnexal complications that occur during or after a procedure and are not classified elsewhere. Use it when the chart documents a postoperative or intraoperative eye disorder, but a more specific code is not available.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include a new eye problem linked to surgery or another procedure, such as inflammation, hemorrhage, retained material, or unexpected visual change.
When to use this code
Use H59 when the provider links the eye disorder to a procedure and the complication is not better described by another ICD-10-CM code. It is appropriate for postoperative follow-up notes that identify a procedure-related eye complication without a more specific diagnosis. Check documentation for the exact complication and timing.
Do not use for
Do not use H59 for routine postoperative care, expected healing, or a complication that has a more specific code elsewhere in ICD-10-CM. Also avoid it when the record does not clearly connect the eye problem to the procedure.
Coding tip
Always code the specific complication first if one is documented; use H59 only when the record supports an eye-related procedural complication but no narrower code fits.
