Questions About T80.0XXSOverview

Is T80.0XXS a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report air embolism following infusion, transfusion and therapeutic injection, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in T80.0XXS mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the air embolism following infusion, transfusion and therapeutic injection itself has resolved, not the original event.

What MS-DRG does T80.0XXS group to?

When air embolism following infusion, transfusion and therapeutic injection, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 923, 922, with relative weights from 0.9980 to 1.6248 depending on complications. Higher weights mean higher Medicare reimbursement.

Is T80.0XXS exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for air embolism following infusion, transfusion and therapeutic injection, sequela on inpatient claims. The code appears in the Complications of surgical and medical care, not elsewhere classified (T80-T88) range of the CMS exempt list.

What is the ICD-9 equivalent of T80.0XXS?

Under the General Equivalence Mappings, air embolism following infusion, transfusion and therapeutic injection, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
