T86.8489 — Other complications of corneal transplant, unspecified eye
Is T86.8489 billable?
Yes, but T86.8489 will trip a Medicare edit. T86.8489 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists T86.8489 under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.
