H93.A1 ICD-10-CM Code: Pulsatile tinnitus, right ear

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 154 — OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES WITH MCC (MDC 03)
  • MS-DRG 155 — OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES WITH CC (MDC 03)
  • MS-DRG 156 — OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES 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.

Relationships & Classification

Potential MS-DRG Relationships (FY2026)

Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.

Named in the grouper logic of 3 MS-DRGs: DRG 154 (MDC 03), DRG 155 (MDC 03), DRG 156 (MDC 03).

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