ICD-10/M26.603

M26.603 ICD-10-CM Code: Bilateral temporomandibular joint disorder, unspecified

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

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, 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)

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.

Official Registry Overview & Definition

Bilateral temporomandibular joint disorder, unspecified is a billable ICD-10-CM diagnosis code (M26.603).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for M26.603 in the official ICD-10-CM tabular list.
