2026 ICD-10-CM Diagnosis Code T82.9XXSUnspecified complication of cardiac and vascular prosthetic device, implant and graft, sequela
T82.9XXS is a billable ICD-10-CM diagnosis code for unspecified complication of cardiac and vascular prosthetic device, implant and graft, sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 922 through 923. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complication, sequela.

Coding GuidelinesGuidance
The appropriate 7th character is to be added to each code from block Complications of cardiac and vascular prosthetic devices, implants and grafts (T82). Use the following options for the applicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Questions About T82.9XXSOverview
Is T82.9XXS a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report unspecified complication of cardiac and vascular prosthetic device, implant and graft, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T82.9XXS mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the unspecified complication of cardiac and vascular prosthetic device, implant and graft itself has resolved, not the original event.
What MS-DRG does T82.9XXS group to?
When unspecified complication of cardiac and vascular prosthetic device, implant and graft, 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 T82.9XXS 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 unspecified complication of cardiac and vascular prosthetic device, implant and graft, sequela on inpatient claims.
What is the ICD-9 equivalent of T82.9XXS?
Under the General Equivalence Mappings, unspecified complication of cardiac and vascular prosthetic device, implant and graft, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
