ICD-10-PCS Codes

ICD-10-PCS Code	Description
0CMX0Z0	Reattachment of Lower Tooth, Single, Open Approach
0CMX0Z1	Reattachment of Lower Tooth, Multiple, Open Approach
0CMX0Z2	Reattachment of Lower Tooth, All, Open Approach
0CMXXZ0	Reattachment of Lower Tooth, Single, External Approach
0CMXXZ1	Reattachment of Lower Tooth, Multiple, External Approach
0CMXXZ2	Reattachment of Lower Tooth, All, External Approach

Typical Clinical Scenarios

A 28-year-old patient presents to the emergency department after a sports-related facial trauma with an avulsed single lower incisor that remained viable and was brought in saline. Because the tooth is a single, separated lower tooth suitable for surgical reattachment to its normal anatomic position, the patient is admitted for operative reattachment using an open approach to inspect and repair supporting tissues. Typical codes: 0CMX0Z0
A 46-year-old patient arrives after a high-impact motor vehicle collision with multiple lower teeth avulsed and contamination of the sockets; inpatient care is required for stabilization, debridement, and coordinated reattachment of the multiple separated lower teeth to restore occlusion and oral function. Due to the need for direct visualization and repair of multiple teeth and surrounding structures, an open surgical reattachment approach is performed. Typical codes: 0CMX0Z1
An elderly patient with a prior traumatic dental injury presents with complete avulsion of all mandibular teeth after a fall; because the clinical goal is to reattach all separated lower teeth to their appropriate positions and the procedure requires external surgical access for comprehensive reconstruction, inpatient reattachment of all lower teeth is undertaken. Typical codes: 0CMXXZ2, 0CMX0Z2
