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

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 T85 Complications of other internal prosthetic devices, implants and grafts applies to 288 codes
  • The appropriate 7th character is to be added to each code from category T85

Questions About T85.898SOverview

Is T85.898S a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified complication of other internal prosthetic devices, implants and grafts, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in T85.898S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the other specified complication of other internal prosthetic devices, implants and grafts itself has resolved, not the original event.

What MS-DRG does T85.898S group to?

When other specified complication of other internal prosthetic devices, implants and grafts, 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 T85.898S 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 specified complication of other internal prosthetic devices, implants and grafts, 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 T85.898S?

Under the General Equivalence Mappings, other specified complication of other internal prosthetic devices, implants and grafts, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
