Coding instructions
Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for K91.6 in the official ICD-10-CM tabular list, quoted as published.
Notes without a marker are published on K91.6 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).

Coder workflow for K91.6
MedCoder structured workflow — derived from this code’s own official record
Before you code K91.6
- K91.6 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).
See the relationships section · Guide: How to choose an ICD-10-CM code →
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with K91.6. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support one of the more specific codes beneath K91.6?
Yes → Select that code and continue the checks below on its own page.
No → K91.6 cannot be reported as written; query for the specificity its subcategory needs. - Does the documentation support a condition named in K91.6’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 K91.6. 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 K91.6(1 note)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with K91.6: 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 K91.6(7 notes)
Coding workflow: The conditions named in this note are not included in K91.6. 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 K91.6 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.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name K91.6 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, T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88), T81 — Complications of procedures, not elsewhere classified (via K91.-), T81 — Complications of procedures, not elsewhere classified, T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts, T83 — Complications of genitourinary prosthetic devices, implants and grafts, T84 — Complications of internal orthopedic prosthetic devices, implants and grafts, T85 — Complications of other internal prosthetic devices, implants and grafts, T86 — Complications of transplanted organs and tissue, T87 — Complications peculiar to reattachment and amputation, T88 — Other complications of surgical and medical care, not elsewhere classified.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Common coding questions
Can K91.6 be billed directly?
No. K91.6 (Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
