ICD-10 Code H59.88 – Other intraoperative complications of eye and adnexa, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.88 – Other intraoperative complications of eye and adnexa, not elsewhere classified
What it is
H59.88 identifies an unspecified intraoperative complication affecting the eye or adnexa during a procedure. Use it when the operative record confirms a complication, but no more specific code fits.
Clinical signs
Clinical features vary; refer to documentation. The record may describe an unexpected surgical event involving ocular tissues, structures around the eye, or a procedure-related injury recognized during surgery.
When to use this code
Use this code when the surgeon documents an intraoperative complication of the eye or adnexa and does not name a more specific category. It is appropriate for coding the complication itself, not the underlying eye disease or the reason for surgery. Check the operative note for laterality, specificity, and whether a different complication code is documented.
Do not use for
Do not use it for postoperative complications, routine surgical findings, or expected operative outcomes. If the complication is described more specifically, code that condition instead.
Coding tip
Query the provider when the note says “complication” but does not clearly identify the intraoperative event.
