T15.90XD ICD-10-CM Code: Foreign body on external eye, part unspecified, unspecified eye, subsequent encounter
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 949 — AFTERCARE WITH CC/MCC (MDC 23)
- MS-DRG 950 — AFTERCARE WITHOUT CC/MCC (MDC 23)
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.
