Upper Tooth Reattachment Procedure Overview

Procedures in this group involve reattachment of an upper tooth to its normal location within the mouth and throat body system following separation or avulsion. These reattachment operations target the upper tooth and surrounding oral structures and require documentation of the surgical reattachment technique and any adjunctive work on supporting tissues. Accurate ICD-10-PCS coding ensures inpatient records reflect the reattachment procedure performed and supports appropriate reimbursement and clinical case mix assignment.

ICD-10-PCS Code	Description
0CMW0Z0	Reattachment of Upper Tooth, Single, Open Approach
0CMW0Z1	Reattachment of Upper Tooth, Multiple, Open Approach
0CMW0Z2	Reattachment of Upper Tooth, All, Open Approach
0CMWXZ0	Reattachment of Upper Tooth, Single, External Approach

Typical Clinical Scenarios

A 9-year-old child presents emergently after a playground fall with an avulsed upper central incisor that is retrieved and brought with the patient. The tooth appears intact but separated from its socket, and the patient is admitted for urgent surgical reimplantation to restore tooth continuity and preserve oral function; an open surgical approach is used to reposition and secure the single tooth. Typical codes: 0CMW0Z0
A 45-year-old patient with facial trauma from a motor vehicle collision has multiple upper teeth partially avulsed and displaced with soft-tissue lacerations; inpatient care is required for surgical repair under general anesthesia. The operative plan includes open reattachment of several affected upper teeth and concurrent management of adjacent oral tissues to reestablish dental occlusion and hemostasis. Typical codes: 0CMW0Z1, 0CMWXZ1
A 32-year-old patient is admitted for management of chronic dental trauma after a failed prior reattachment where all upper anterior teeth require revision and reattachment; the procedure is performed via an external approach with comprehensive reattachment of the entire upper tooth segment. Typical codes: 0CMW0Z2, 0CMWXZ2
