Pacemakers and Implantable Defibrillators
An arrhythmia is any disorder of your heart rate or rhythm. It means that your heart beats too quickly, too slowly, or with an irregular pattern. Most arrhythmias result from problems in the electrical system of the heart. If your arrhythmia is serious, you may need a cardiac pacemaker or an implantable cardioverter defibrillator (ICD).

Questions About T82.110SOverview
Is T82.110S (Breakdown (mechanical) of cardiac electrode) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report breakdown (mechanical) of cardiac electrode, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T82.110S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the breakdown (mechanical) of cardiac electrode itself has resolved, not the original event.
What MS-DRG does T82.110S group to?
When breakdown (mechanical) of cardiac electrode, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 922, 923, with relative weights from 1.0177 to 1.7494 depending on complications. Higher weights mean higher Medicare reimbursement.
Is T82.110S 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 breakdown (mechanical) of cardiac electrode, sequela on inpatient claims.
What is the ICD-9 equivalent of T82.110S?
Under the General Equivalence Mappings, breakdown (mechanical) of cardiac electrode, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
