2026 ICD-10-CM Diagnosis Code T81.89XSOther complications of procedures, not elsewhere classified, sequela
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 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 procedures, not elsewhere classified (T81). Use the following options for the applicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Clinical InformationClinical
Postoperative Hemorrhage
hemorrhage following any surgical procedure. it may be immediate or delayed and is not restricted to the surgical wound.Cytokine Release Syndrome
a severe immune reaction characterized by excessive release of cytokines. symptoms include dyspnea; fever; headache; hypotension; nausea; rash; tachycardia; hypoxia; hyperferritinemia, and multiple organ failure. it is associated with viral infections, sepsis; autoimmune diseases and a variety of factors used in immunotherapy.Seroma
tumor-like sterile accumulation of serum in a tissue, organ, or cavity. it results from a tissue insult and is the product of tissue inflammation. it most commonly occurs following mastectomy.Trismus
spasmodic contraction of the masseter muscle resulting in forceful jaw closure. this may be seen with a variety of diseases, including tetanus, as a complication of radiation therapy, trauma, or in association with neoplastic conditions.Mastectomy
surgical procedure to remove one or both breasts.Tetanus
a disease caused by tetanospasmin, a powerful protein toxin produced by clostridium tetani. tetanus usually occurs after an acute injury, such as a puncture wound or laceration. generalized tetanus, the most common form, is characterized by tetanic muscular contractions and hyperreflexia. localized tetanus presents itself as a mild condition with manifestations restricted to muscles near the wound. it may progress to the generalized form.Grade 1 Seroma, CTCAE|Grade 1 Seroma|Grade 1 Seroma

Questions About T81.89XSOverview
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, 2025 through September 30, 2026.
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 922, 923, with relative weights from 1.0177 to 1.7494 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.
What is the ICD-9 equivalent of T81.89XS?
Under the General Equivalence Mappings, other complications of procedures, not elsewhere classified, sequela converts to ICD-9-CM 909.3 (late eff surg/med compl). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
