ICD-10-PCS Code For Upper Arm Tendon, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0LX4 includes procedures performed to transfer tendons in the left upper arm. These ICD-10-PCS codes are used for inpatient documentation when a tendon is moved to a new location to assume the function of all or part of another tendon or muscle. Accurate coding within the ICD-10-PCS 0LX4 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Upper Arm Tendon Transfer Procedure Overview

This procedure group includes tendon transfer operations on the left upper arm targeting the tendons body system to restore or reassign function. These procedures move, without removing, all or part of a tendon to a new location to assume the function of another tendon or muscle. Accurate coding is important for inpatient reimbursement because it documents the root operation and specific body part treated, which affects case mix and payment.

Typical Clinical Scenarios

A middle-aged construction worker presents electively for restoration of wrist and finger extension after a chronic radial nerve palsy has led to irreversible loss of function in the original extensor tendons; after clinical evaluation and inpatient surgical planning, a functioning left upper arm tendon is mobilized and transferred to assume lost extensor function to improve hand mechanics and enable early supervised rehabilitation. Typical codes: 0LX40ZZ, 0LX44ZZ
An elderly patient is admitted after a fall resulting in a complex open left upper arm tendon laceration with contamination and loss of distal tendon attachments; once soft-tissue viability is assessed and infection risk addressed, the surgical team performs a tendon transfer to reestablish shoulder or elbow-related tendon function as part of the acute inpatient reconstruction. Typical codes: 0LX40ZZ
A younger patient returns to the operating room for revision of a previously failed tendon repair with persistent functional deficit despite prior procedures; intraoperative decision is made to relocate a segment of a healthy left upper arm tendon to take over the deficient tendon’s function to improve strength and range of motion during the same inpatient admission. Typical codes: 0LX40ZZ
