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 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 157 — DENTAL AND ORAL DISEASES WITH MCC (MDC 03)
  • MS-DRG 158 — DENTAL AND ORAL DISEASES WITH CC (MDC 03)
  • MS-DRG 159 — DENTAL AND ORAL DISEASES WITHOUT CC/MCC (MDC 03)
  • MS-DRG 795 — NORMAL NEWBORN (MDC 15)

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.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for K00.6 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on K00.6 itself; “inherited from” names the category or block whose note applies here.

Inclusion Terms

  • Dentia praecox
  • Natal tooth
  • Neonatal tooth
  • Premature eruption of tooth
  • Premature shedding of primary [deciduous] tooth
  • Prenatal teeth
  • Retained [persistent] primary tooth

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

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).

Official instructions as workflow

  • Excludes2 — not part of K00.6(1 note)

    Coding workflow: The conditions named in this note are not included in K00.6. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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.

Code Overview

Disturbances in tooth eruption is a billable ICD-10-CM diagnosis code (K00.6).

Indexed Clinical Terms (15)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Official Coding Guidelines

No excerpt in the ICD-10-CM Official Guidelines names this code specifically. Its chapter carries only this chapter-wide note:

Chapter 11: Diseases of the Digestive System (K00-K95)

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 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 7 MS-DRGs: DRG 011 (MDC PRE), DRG 012 (MDC PRE), DRG 013 (MDC PRE), DRG 157 (MDC 03), DRG 158 (MDC 03), DRG 159 (MDC 03), DRG 795 (MDC 15).

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

Clinical classification (AHRQ CCSR):DIG002 — Disorders of teeth and gingiva (default); DEN001 — Any dental condition including traumatic injury; DEN002 — Nontraumatic dental conditions.
