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 v44, Appendix B.

  • MS-DRG 385 — INFLAMMATORY BOWEL DISEASE WITH MCC (MDC 06)
  • MS-DRG 386 — INFLAMMATORY BOWEL DISEASE WITH CC (MDC 06)
  • MS-DRG 387 — INFLAMMATORY BOWEL DISEASE WITHOUT CC/MCC (MDC 06)

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 78 — Intestinal Obstruction/Perforation
  • HCC 80 — Crohn's Disease (Regional Enteritis) (supersedes HCC 81)

Other models: CMS-HCC V22 HCC 33 · CMS-HCC V22 HCC 35 · RxHCC V08 HCC 67

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

Coder workflow for K50.812

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

Before you code K50.812

  1. K50.812’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

    Guide: Combination codes →

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with K50.812. 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 K50.812’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.

    ReviewK51, K58, K59.3

Consider K50.812. Then work the Use Additional Code 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 associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.

Official instructions as workflow

  • Excludes1 — check before selecting K50.812(3 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with K50.812: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareK51, K58, K59.3

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

  • Use Additional Code — after identifying K50.812(6 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with K50.812 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

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

Documentation: Both the condition K50.812 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).

ReviewK51, K58, K59.3

Documentation: Only one of the components this code’s title joins is documented.

Coding question: Is K50.812 supported?

Path: Review the code for the documented component on its own.

Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with K50.812?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

ReviewK60.3, K60.5, K60.4, L88

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-derived relationships — computed from published CMS and AHRQ datasets

Other codes that name K50.812 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 3 Excludes1 notes across 2 chapters: E55.0 — Rickets, active (via K50.-), K50.0 — Crohn's disease of small intestine (via K50.8.-), K51 — Ulcerative colitis (via K50.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 1 Excludes2 note: M04 — Autoinflammatory syndromes (via K50.-).

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

Referenced by 3 Code First instructions: K60.3 — Anal fistula (via K50.-), K60.4 — Rectal fistula (via K50.-), K60.5 — Anorectal fistula (via K50.-).

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.

Referenced by 2 Code Also instructions: M07 — Enteropathic arthropathies (via K50.-), M08 — Juvenile arthritis (via K50.-).

These codes suggest coding this condition alongside when both are present.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: 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 77 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 385 (MDC 06), DRG 386 (MDC 06), DRG 387 (MDC 06).

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

Clinical classification (AHRQ CCSR):DIG011 — Regional enteritis and ulcerative colitis (default); DIG012 — Intestinal obstruction and ileus.
