ICD-10-PCS Code For Salivary Gland: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0C2A includes procedures performed to change a device in the salivary gland. These ICD-10-PCS codes are used for inpatient documentation when an identical or similar device is removed from a salivary gland and a replacement device is placed without cutting or puncturing the skin or a mucous membrane. Accurate coding within the ICD-10-PCS 0C2A group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Salivary Gland Change Procedure Overview

Procedures in this group involve changing an identical or similar device on or in the salivary gland without cutting or puncturing the skin or a mucous membrane. These codes target the mouth and throat body system and reflect a noninvasive exchange of a device already in place. Accurate coding is important for inpatient reimbursement because it documents the specific root operation and anatomical site, supporting correct case mix and payment.

When to Use

Use a code from this group when an inpatient procedure involves exchanging a device in the salivary gland and the entry does not involve incision or puncture of skin or mucosa. Select these codes when the replacement is identical or similar to the original device and the procedure is documented as a change.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
0C2AX0Z	Change Drainage Device in Salivary Gland, External Approach
0C2AXYZ	Change Other Device in Salivary Gland, External Approach

Typical Clinical Scenarios

An elderly patient with a long-term external salivary duct drainage catheter becomes admitted for acute dehydration and concern for catheter malfunction after noticing decreased saliva output and pericatheter leakage; imaging and bedside exam confirm the existing external drainage device is blocked but no new incision is required to exchange it, so the device is removed and an identical external drainage catheter is placed at the same duct orifice to restore function. Typical codes: 0C2AX0Z
A middle-aged patient with Sjögren-like chronic sialadenitis has a previously placed external intraoral salivary gland stent that has migrated and is causing recurrent obstruction and pain; during a planned inpatient procedure under sedation the migrated stent is removed and an equivalent external device is repositioned without cutting the mucosa. Typical codes: 0C2AX0Z, 0C2AXYZ
A postoperative patient develops external salivary gland device-related skin irritation and device failure after head and neck surgery; because the original external drainage device is nonfunctional and causing local complications but the tract is mature, the care team elects to remove the failed external device and place a similar external drainage device at the same site to maintain salivary drainage and allow wound healing. Typical codes: 0C2AX0Z
