Summary & Overview

HCPCS L6672: Upper Extremity Saddle-Type Chest/Shoulder Harness

HCPCS Level II code L6672 designates an upper extremity addition: a saddle-type harness that anchors to the chest or shoulder to provide support and stabilization for the arm. These orthotic additions are used in managing functional deficits, supporting prosthetic or orthotic devices, or improving positioning and load distribution for patients with upper-limb weakness or deformity. Nationally, clear coding for orthotic additions like L6672 matters for claims adjudication, durable medical equipment supply chains, and clinical care coordination.

Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication presents payor coverage patterns, coding and billing guidance, and clinical context for use of saddle-type chest or shoulder harnesses for the upper extremity.

Readers will find concise benchmarks for utilization and reimbursement where available, summaries of relevant policy language and documentation expectations, and clinical context describing typical indications and sites of service for this orthotic addition. Data not available in the input is noted where applicable; the focus remains on national-level implications for billing, supplier workflows, and clinical teams managing orthotic care.

Billing Code Overview

HCPCS Level II code L6672 describes an upper extremity addition, harness, chest or shoulder, saddle type. This item is an orthotic component intended to provide structural support and stabilization for the upper limb by anchoring to the chest or shoulder with a saddle-style harness.

Service Type: Orthotic supply/addition for upper extremity support

Typical Site of Service: Outpatient durable medical equipment (DME) setting, orthotics clinic, or durable medical equipment supplier

Clinical & Coding Specifications

Clinical Context

A 42-year-old patient with a chronic brachial plexus injury and glenohumeral instability is being fitted for an upper-extremity prosthetic/orthotic harness addition. The orthotist evaluates shoulder and chest anatomy, measures for a saddle-type harness that secures an upper-extremity orthosis or prosthetic to the torso, and documents functional limitations and goals. The clinical workflow includes: initial evaluation and measurements by an orthotist; fabrication or adjustment of the L6672 harness addition (saddle type) to interface with an existing prosthetic or orthotic device; a fitting appointment to verify fit, alignment, and comfort; patient education on donning/doffing and skin care; and a follow-up visit for adjustments. Typical settings are an orthotics and prosthetics clinic, outpatient rehabilitation center, or hospital prosthetics department. Common patients include those with upper-limb amputation, severe shoulder weakness, or neurological impairment requiring chest/shoulder stabilization for prosthetic control.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`S48.011A`	Strain of muscle, fascia and tendon of right shoulder region, initial encounter.	Shoulder strains may impair shoulder girdle stability, increasing need for chest/shoulder harness support when using an upper-extremity orthosis.
`S48.012A`	Strain of muscle, fascia and tendon of left shoulder region, initial encounter.	Left-sided shoulder dysfunction affecting suspension or control of an orthosis; harness addition may be indicated.
`S48.121A`	Avulsion of muscle, fascia and tendon of right shoulder region, initial encounter.	Structural injury compromising shoulder anchoring necessitating a saddle-type harness for prosthetic suspension.
`S48.122A`	Avulsion of muscle, fascia and tendon of left shoulder region, initial encounter.	Same relevance for left-sided injury requiring chest/shoulder harness support.
`G54.4`	Brachial plexus disorders.	Brachial plexus injury often causes severe shoulder weakness or paralysis; harness additions provide trunk-based suspension for prosthetic control.
`Z43.1`	Fitting and adjustment of external prosthetic device.	Billing and documentation often accompany prosthetic harness additions and follow-up fittings.
`T87.8XXA`	Other complications of prosthetic device, initial encounter.	Used when complications of a prior prosthesis or harness necessitate modification or a new `L6672` addition.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`97760`	Orthotic management and training, initial encounter; lower or upper extremity, with training of patient/caregiver in use and care.	Often performed at the fitting visit to train the patient in safe donning, doffing, and function of the saddle-type harness.
`99070`	Supplies and materials (except spectacles) provided by the physician over and above those usually included with the office visit.	Used when additional non-standard supplies are provided with the harness during the office encounter.
`97763`	Orthotic/prosthetic management and training, initial encounter for custom fabricated device.	Billed for training and functional assessment when a custom harness addition like `L6672` is provided.
`97035`	Ultrasound therapy (therapeutic).	May be used in preparatory therapy visits for skin or soft-tissue conditions before fitting (if clinically applicable).
`99455`	Work-related or medical disability examination by treating physician with medical record review, form completion, and report.	Occasionally used when documentation for workplace prosthetic use or restrictions is required after provision of the harness.
