Z93.2 ICD-10-CM Code: Ileostomy status

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

Coding at a Glance

Tabular directives
2 inclusion terms · 2 Excludes1 · 1 code-also instruction
Risk adjustment
CMS-HCC V28: 1 category · CMS-HCC V22 category 188

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 951 — OTHER FACTORS INFLUENCING HEALTH STATUS (MDC 23)

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.

Risk Adjustment (CMS-HCC)

Payment categories this diagnosis maps to under CMS-HCC V28, payment year 2026.

  • HCC 463 — Artificial Openings for Feeding or Elimination

Other models: CMS-HCC V22 HCC 188

Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.

Coder workflow for Z93.2

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

Before you code Z93.2

  1. Confirm the reason for the encounter this Z code records: a status — a condition, carrier state or sequela that may affect care, distinct from a current complication of it. Check whether the code may be reported as first-listed or principal — some Z codes are limited to one position — and do not report a history or status code for a condition documented as current. Z code categories and their reporting positions (Guidelines I.C.21.c.3, I.C.21.c.15).

    Guide: Status codes (Z codes) →

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with Z93.2. 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 Z93.2’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.

    ReviewZ43, J95.0, K94, N99.5

Consider Z93.2. Then review the Code Also note, and 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).
The reason for the encounter
Whether the code records the encounter’s purpose, a status, or a history — and whether it may be first-listed (Guidelines I.C.21.c).

Official instructions as workflow

  • Excludes1 — check before selecting Z93.2(2 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with Z93.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareZ43, J95.0, K94, N99.5

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

  • Code Also — related condition(1 note)

    Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

    See the official tabular notes · Guidelines I.A.17

Coding decision scenarios

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

Documentation: Both the condition Z93.2 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).

Chapter 21: Factors influencing health status and contact with health services (Z00-Z99)

Code Z92.82 is only applicable to the receiving facility record and not to the transferring facility record. Z93 Artificial opening status Z94 Transplanted organ and tissue status Z95 Presence of cardiac and vascular implants and grafts Z96 Presence of other functional implants Z97 Presence of other devices Z98 Other postprocedural states Assign code Z98.85, Transplanted organ removal status, to indicate that a transplanted organ has been previously removed. This code should not be assigned for the encounter in which the transplanted organ is removed. The complication necessitating removal of the transplant organ should be assigned for that encounter.

Chapter 21: Factors influencing health status and contact with health services (Z00-Z99)

Z99 Dependence on enabling machines and devices, not elsewhere classified Note: Categories Z89-Z90 and Z93-Z99 are for use only if there are no complications or malfunctions of the organ or tissue replaced, the amputation site or the equipment on which the patient is dependent.

Verify Before Coding

  • Principal-diagnosis restriction. The Medicare Code Editor lists this code as unacceptable as a principal diagnosis: it describes a circumstance influencing health status rather than a current illness or injury being treated. It is valid as a secondary diagnosis.

Common coding questions

Can Z93.2 be a principal diagnosis?

No on a Medicare inpatient claim — Z93.2 is on the MCE unacceptable-principal-diagnosis list (v43.1, edit 09). An encounter genuinely about the ileostomy belongs to Z43.2 or the K94.- complication family under Z93’s Excludes1; see When can a Z code be the primary diagnosis? for the full logic.

Does Z93.2 cover an ileal pouch or Kock pouch?

Yes. The tabular lists “Ileal pouch status” and “Kock pouch status” as inclusion terms under Z93.2, so a continent ileostomy reservoir is reported with the same status code as a conventional ileostomy.

What do I code for an ileostomy complication instead of Z93.2?

A code from the K94.- family that Z93’s Excludes1 names — K94.1- carries the enterostomy complication codes (hemorrhage, infection, malfunction, other). The complication code already establishes that the patient has the stoma, so Z93.2 is not added alongside it.
