H25.21 ICD-10-CM Code: Age-related cataract, morgagnian type, right eye
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 124 — OTHER DISORDERS OF THE EYE WITH MCC OR THROMBOLYTIC AGENT (MDC 02)
- MS-DRG 125 — OTHER DISORDERS OF THE EYE WITHOUT MCC (MDC 02)
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.

Verify Before Coding
- Billable — reportable as written.
- Age-restricted: the Medicare Code Editor lists this as a adult (age 15-124) diagnosis; other ages are presumed incorrect.
From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim.

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 124 (MDC 02), DRG 125 (MDC 02).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
