K25.7 ICD-10-CM Code: Chronic gastric ulcer without hemorrhage or perforation

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

Coding at a Glance

Tabular directives
3 inclusion terms · 2 Excludes1 · 1 Excludes2 · 2 use-additional codes

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 380 — COMPLICATED PEPTIC ULCER WITH MCC (MDC 06)
  • MS-DRG 381 — COMPLICATED PEPTIC ULCER WITH CC (MDC 06)
  • MS-DRG 382 — COMPLICATED PEPTIC ULCER WITHOUT CC/MCC (MDC 06)
  • MS-DRG 383 — UNCOMPLICATED PEPTIC ULCER WITH MCC (MDC 06)
  • MS-DRG 384 — UNCOMPLICATED PEPTIC ULCER WITHOUT 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.

Coder workflow for K25.7

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

Before you code K25.7

  1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with K25.7. 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 K25.7’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.

    ReviewK29.0, K27

Consider K25.7. 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).
Acuity
Acute or chronic as documented; when both are documented and separate codes exist, both are reported with the acute code first (Guidelines I.B.8).
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 K25.7(2 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with K25.7: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareK29.0, K27

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

  • Excludes2 — not part of K25.7(1 note)

    Coding workflow: The conditions named in this note are not included in K25.7. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareK44

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

  • Use Additional Code — after identifying K25.7(2 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with K25.7 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 K25.7 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).

ReviewK29.0, K27

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

Coding question: Is a second code reported with K25.7?

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).

ReviewF10

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.

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of K25.7 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

  • K29.0— Excludes1 conflict (Excludes1 — generally not reported together)

    Not coded here — the tabular list excludes this pair for the same encounter.

    Not reported together with this code, except where the two conditions are documented as unrelated.

    What moves you there: Documentation of acute gastritis moves the case to K29.0; the two are not reported together unless documented as unrelated.

  • K27— Excludes1 conflict (Excludes1 — generally not reported together)

    Not coded here — the tabular list excludes this pair for the same encounter.

    Not reported together with this code, except where the two conditions are documented as unrelated.

    What moves you there: Documentation of peptic ulcer NOS moves the case to K27; the two are not reported together unless documented as unrelated.

  • K25.4— Specificity relationship (Review)

    Overlapping diagnoses in the same category.

    Overlapping codes in the same category — the documentation decides which is the more specific fit.

    What moves you there: A record that documents no more than “Chronic or unspecified gastric ulcer with hemorrhage” takes K25.4; specificity in the record moves it back here.

  • K44— Excludes2 relationship (Informational)

    Distinct conditions — both may be reported.

    A distinct condition — both may be reported when both are documented.

    What moves you there: Documentation of hiatus hernia adds K44; it is not part of this code and both may be reported when both are documented.

Relationships are read from this code's own official notes, its laterality siblings and its encounter family; the wording of each distinction is MedCoder editorial, and the documentation named in each “what moves you there” line is the official note phrase or sibling title itself.

Referenced by 2 Excludes1 notes: K29.0 — Acute gastritis (via K25.-), K92.2 — Gastrointestinal hemorrhage, unspecified (via K25.-).

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

Referenced by 1 Code First instruction: F54 — Psychological and behavioral factors associated with disorders or diseases classified elsewhere (via K25.-).

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.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 5 MS-DRGs: DRG 380 (MDC 06), DRG 381 (MDC 06), DRG 382 (MDC 06), DRG 383 (MDC 06), DRG 384 (MDC 06).

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