ICD-10/R93.429

R93.429 ICD-10-CM Code: Abnormal radiologic findings on diagnostic imaging of unspecified kidney

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 695 — KIDNEY AND URINARY TRACT SIGNS AND SYMPTOMS WITH MCC (MDC 11)
  • MS-DRG 696 — KIDNEY AND URINARY TRACT SIGNS AND SYMPTOMS WITHOUT MCC (MDC 11)

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

Abnormal radiologic findings on diagnostic imaging of unspecified kidney is a billable ICD-10-CM diagnosis code (R93.429).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for R93.429 in the official ICD-10-CM tabular list.

Includes

Conditions the official ICD-10-CM tabular list includes under this code.

  • nonspecific abnormal findings on diagnostic imaging by computerized axial tomography [CAT scan]
  • nonspecific abnormal findings on diagnostic imaging by magnetic resonance imaging [MRI][NMR]
  • nonspecific abnormal findings on diagnostic imaging by positron emission tomography [PET scan]
  • nonspecific abnormal findings on diagnostic imaging by thermography
  • nonspecific abnormal findings on diagnostic imaging by ultrasound [echogram]
  • nonspecific abnormal findings on diagnostic imaging by X-ray examination

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

  • abnormal findings on antenatal screening of mother (O28.-) Compare R93.429 vs O28 →
  • diagnostic abnormal findings classified elsewhere - see Alphabetical Index

Excludes2 — Not Included Here

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

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 2 MS-DRGs: DRG 695 (MDC 11), DRG 696 (MDC 11).

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