K91.62 ICD-10-CM Code: Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating other procedure

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Coding at a Glance

Tabular directives
1 Excludes1 · 7 Excludes2

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43, Appendix B.

  • MS-DRG 919 — COMPLICATIONS OF TREATMENT WITH MCC (MDC 21)
  • MS-DRG 920 — COMPLICATIONS OF TREATMENT WITH CC (MDC 21)
  • MS-DRG 921 — COMPLICATIONS OF TREATMENT WITHOUT CC/MCC (MDC 21)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for K91.62 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on K91.62 itself; “inherited from” names the category or block whose note applies here.

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Coder workflow for K91.62

MedCoder structured workflow — derived from this code’s own official record

Before you code K91.62

  1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with K91.62. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Does the documentation support a condition named in K91.62’s Excludes1 note?
    Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
    No → Continue.

    ReviewK91.7

Consider K91.62. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).

Official instructions as workflow

  • Excludes1 — check before selecting K91.62(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with K91.62: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareK91.7

    See the official tabular notes · Guidelines I.A.12.a

  • Excludes2 — not part of K91.62(7 notes)

    Coding workflow: The conditions named in this note are not included in K91.62. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: Both the condition K91.62 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewK91.7

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Code Overview

Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating other procedure is a billable ICD-10-CM diagnosis code (K91.62).

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Official Coding Guidelines

No excerpt in the ICD-10-CM Official Guidelines names this code specifically. Its chapter carries only this chapter-wide note:

Chapter 11: Diseases of the Digestive System (K00-K95)

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name K91.62 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 11 Excludes2 notes: T80 — Complications following infusion, transfusion and therapeutic injection (via K91.6.-), T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88) (via K91.6.-), T81 — Complications of procedures, not elsewhere classified (via K91.-), T81 — Complications of procedures, not elsewhere classified (via K91.6.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts (via K91.6.-), T83 — Complications of genitourinary prosthetic devices, implants and grafts (via K91.6.-), T84 — Complications of internal orthopedic prosthetic devices, implants and grafts (via K91.6.-), T85 — Complications of other internal prosthetic devices, implants and grafts (via K91.6.-), T86 — Complications of transplanted organs and tissue (via K91.6.-), T87 — Complications peculiar to reattachment and amputation (via K91.6.-), T88 — Other complications of surgical and medical care, not elsewhere classified (via K91.6.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 76 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 919 (MDC 21), DRG 920 (MDC 21), DRG 921 (MDC 21).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Clinical classification (AHRQ CCSR):DIG024 — Postprocedural or postoperative digestive system complication (default).
