Coder workflow for K94.0
MedCoder structured workflow — derived from this code’s own official record
Before you code K94.0
- K94.0 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).

Choose the right path
- Does the documentation support one of the more specific codes beneath K94.0?
Yes → Select that code and continue the checks below on its own page.
No → K94.0 cannot be reported as written; query for the specificity its subcategory needs.
Consider K94.0. 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).
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 K94.0 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 2 Excludes1 notes: Z43 — Encounter for attention to artificial openings (via K94.-), Z93 — Artificial opening status (via K94.-).
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 22 Excludes2 notes across 2 chapters: K62 — Other diseases of anus and rectum, K91 — Intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified (via K94.-), T80 — Complications following infusion, transfusion and therapeutic injection (via K94.-), T80 — Complications following infusion, transfusion and therapeutic injection, T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88) (via K94.-), T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88), T81 — Complications of procedures, not elsewhere classified, T81 — Complications of procedures, not elsewhere classified (via K94.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts (via K94.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts, T83 — Complications of genitourinary prosthetic devices, implants and grafts, T83 — Complications of genitourinary prosthetic devices, implants and grafts (via K94.-), T84 — Complications of internal orthopedic prosthetic devices, implants and grafts, T84 — Complications of internal orthopedic prosthetic devices, implants and grafts (via K94.-), T85 — Complications of other internal prosthetic devices, implants and grafts, T85 — Complications of other internal prosthetic devices, implants and grafts (via K94.-), T86 — Complications of transplanted organs and tissue (via K94.-), T86 — Complications of transplanted organs and tissue, T87 — Complications peculiar to reattachment and amputation (via K94.-), T87 — Complications peculiar to reattachment and amputation, +2 more.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
