When to Use

Use a code from this group when an inpatient procedure is performed to correct or revise a finger nail, such as repair of a displaced nail or removal and reconstruction of damaged nail tissue. These codes apply when the operation’s intent is revision of the nail structure rather than primary excision or drainage.

ICD-10-PCS Codes

4 rows

ICD-10-PCS Code	Description
0HWQX0Z	Revision of Drainage Device in Finger Nail, External Approach
0HWQX7Z	Revision of Autologous Tissue Substitute in Finger Nail, External Approach
0HWQXJZ	Revision of Synthetic Substitute in Finger Nail, External Approach
0HWQXKZ	Revision of Nonautologous Tissue Substitute in Finger Nail, External Approach

Typical Clinical Scenarios

A middle-aged patient presents to the inpatient unit after traumatic avulsion of the fingernail from a crush injury. The nail bed is partially displaced with retained devitalized nail plate fragments and the surgeon performs a revision to reposition and repair the remaining nail structure via an external approach to preserve function. The procedure targets the finger nail and is undertaken to correct the displaced nail tissue and restore normal anatomy. Typical codes: 0HWQX0Z
An elderly patient is admitted electively for planned revision of a previously placed biologic nail reconstruction that has not integrated and is causing recurrent irritation. The operation involves removal and revision of the autologous tissue substitute at the finger nail using an external approach to correct the malposition and improve fit and comfort. This is performed to revise the failed substitute and restore proper nail contour. Typical codes: 0HWQX7Z
A patient with prior synthetic nail reconstruction develops persistent infection and displacement of the synthetic material, requiring operative management during the same inpatient stay. The surgeon revises the synthetic substitute at the finger nail through an external approach, removing malpositioned material and repairing the nail complex to address the complication. The goal is correction of the malfunctioning implant and resolution of the associated tissue problem. Typical codes: 0HWQXJZ
