T82.510S is a billable ICD-10-CM diagnosis code for breakdown (mechanical) of surgically created arteriovenous fistula, 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 2027 (October 1, 2026 through September 30, 2027) 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

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to T82.510S: its own notes plus those printed at T82.5, T82, block T80-T88, and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Block T80-T88 Complications of surgical and medical care, not elsewhere classified applies to 1,683 codes
  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

From T82 Complications of cardiac and vascular prosthetic devices, implants and grafts applies to 297 codes
  • The appropriate 7th character is to be added to each code from category T82
Values for category T82 Encounter: Initial, Subsequent, Sequela

Questions About T82.510SOverview

Is T82.510S a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report breakdown (mechanical) of surgically created arteriovenous fistula, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in T82.510S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the breakdown (mechanical) of surgically created arteriovenous fistula itself has resolved, not the original event.

What MS-DRG does T82.510S group to?

When breakdown (mechanical) of surgically created arteriovenous fistula, 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 T82.510S 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 surgically created arteriovenous fistula, 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 T82.510S?

Under the General Equivalence Mappings, breakdown (mechanical) of surgically created arteriovenous fistula, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
