CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

T81.89XS is a billable ICD-10-CM diagnosis code for other complications of procedures, not elsewhere classified, 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 procedures, not elsewhere classified (T81). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructions from the official ICD-10-CM Tabular List that apply to T81.89XS: its own notes plus those printed at T81.89, T81.8, T81, block T80-T88, and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From T81.8 Other complications of procedures, not elsewhere classified applies to 12 codes
  • hypothermia following anesthesia (T88.51)
  • malignant hyperpyrexia due to anesthesia (T88.3)

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 T81 Complications of procedures, not elsewhere classified applies to 240 codes
  • The appropriate 7th character is to be added to each code from category T81
Values for category T81 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela this code

Questions About T81.89XSOverview

What is the ICD-10 code for other complications of procedures, not elsewhere classified, sequela?

The ICD-10-CM code for other complications of procedures, not elsewhere classified, sequela is T81.89XS (sometimes written as T8189XS). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is T81.89XS (Other complications of procedures, not elsewhere classified) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other complications of procedures, not elsewhere classified, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in T81.89XS mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the other complications of procedures, not elsewhere classified itself has resolved, not the original event.

What MS-DRG does T81.89XS group to?

When other complications of procedures, not elsewhere classified, 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 T81.89XS 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 other complications of procedures, not elsewhere classified, 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.
