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 011 — TRACHEOSTOMY FOR FACE, MOUTH AND NECK DIAGNOSES OR LARYNGECTOMY WITH MCC (MDC PRE)
- MS-DRG 012 — TRACHEOSTOMY FOR FACE, MOUTH AND NECK DIAGNOSES OR LARYNGECTOMY WITH CC (MDC PRE)
- MS-DRG 013 — TRACHEOSTOMY FOR FACE, MOUTH AND NECK DIAGNOSES OR LARYNGECTOMY WITHOUT CC/MCC (MDC PRE)
- MS-DRG 152 — OTITIS MEDIA AND URI WITH MCC (MDC 03)
- MS-DRG 153 — OTITIS MEDIA AND URI WITHOUT MCC (MDC 03)
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 J37.0
MedCoder structured workflow — derived from this code’s own official record
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 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
Excludes2 — not part of J37.0(2 notes)
Coding workflow: The conditions named in this note are not included in J37.0. When the record documents both, both may be reported; the note is a boundary, not a prohibition.
See the official tabular notes · Guidelines I.A.12.b
Use Additional Code — after identifying J37.0(8 notes)
Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with J37.0 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.
ReviewZ77.22, P96.81, Z87.891, Z57.31, F17, Z72.0
See the official tabular notes · Guidelines I.A.13
Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: A condition the Use Additional Code note names is documented.
Coding question: Is a second code reported with J37.0?
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).
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.

Relationships & Classification
MedCoder-derived relationships — computed from published CMS and AHRQ datasets
Other codes that name J37.0 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 Excludes2 notes: J04.0 — Acute laryngitis, J05.1 — Acute epiglottitis.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
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 011 (MDC PRE), DRG 012 (MDC PRE), DRG 013 (MDC PRE), DRG 152 (MDC 03), DRG 153 (MDC 03).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
