ICD-10/S99.239G

S99.239G ICD-10-CM Code: Salter-Harris Type III physeal fracture of phalanx of unspecified toe, subsequent encounter for fracture with delayed healing

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.

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.
