Coder workflow for K94.0

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

Before you code K94.0

  1. 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).

    ReviewK94.00, K94.01, K94.02, K94.03, K94.09

    See the relationships section · Guide: How to choose an ICD-10-CM code →

Choose the right path

  1. 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. Where the codes beneath it include an unspecified code, that code applies when the record goes no further; otherwise query for the missing detail.

    ReviewK94.00, K94.01, K94.02, K94.03, K94.09

Report the code beneath K94.0 that the documentation supports, not K94.0 itself. Then confirm that code is valid for the date of service on its own page.

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.

Coding context

Guidelines, coding notes, decision aids, relationships (with MS-DRG and CCSR classification), hierarchy, HCC, coverage and the context map: what a coder reaches for after the core. Each section names whether it is official source data, a MedCoder-derived relationship or MedCoder editorial.

Code Overview

Colostomy complications is a non-billable ICD-10-CM category code (K94.0). A more specific billable subcode must be selected for claims submission.

Relationships & Classification

MedCoder-derived 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.
