Summary & Overview

CPT 29085: Application of Hand and Lower Forearm Gauntlet Cast

CPT 29085 denotes the application of a gauntlet cast to the hand and lower forearm, a common immobilization procedure for fractures and soft-tissue injuries of the distal forearm and hand. Nationally, this code is widely used in outpatient and physician office settings where prompt, localized immobilization is required to stabilize injuries and support healing. The code is relevant to orthopaedic surgeons, hand specialists, emergency medicine clinicians, and outpatient procedural teams.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common scenarios that prompt use of 29085. The publication outlines related CPTs for upper-extremity casting to clarify code selection and billing context. It also identifies common ICD-10 diagnoses that align with the service and notes typical modifiers used to indicate laterality.

This summary equips billing managers, clinicians, and compliance staff with an understanding of where 29085 fits in musculoskeletal care pathways, how it relates to neighboring cast application codes, and the payer landscape likely to adjudicate claims.

CPT Code Overview

CPT 29085 describes the application of a gauntlet cast to the hand and lower forearm. This procedure involves molding and applying a cast that covers the lower forearm and the hand in a gauntlet-style configuration to immobilize musculoskeletal injuries of the hand and distal forearm.

Service type: Application of casts – musculoskeletal

Typical site of service: Outpatient clinic or physician office (e.g., POS 11)

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult who presents to an outpatient orthopaedic or emergency medicine clinic with acute wrist or hand trauma after a fall or impact. The patient reports pain, swelling, and limited wrist or hand motion. Physical exam and plain radiographs confirm an isolated distal radius or hand fracture suitable for nonoperative management. The clinician selects a hand and lower forearm gauntlet cast to immobilize the wrist and metacarpal region while allowing partial finger motion. The procedure is performed in the clinic procedure room: the clinician or trained staff prepares the extremity, applies stockinette and padding, molds plaster or fiberglass material into a gauntlet that extends from the palmar/volar hand across the lower forearm, and confirms fit and circulation before discharge with follow-up instructions and a scheduled follow-up visit for radiographic reassessment.

Coding Specifications

LT and RT modifiers:

LT: Use when the cast application is for the left hand and lower forearm.
RT: Use when the cast application is for the right hand and lower forearm.

Associated provider taxonomies:

207X00000X — Orthopaedic Surgery: physicians specializing in surgical and nonoperative musculoskeletal care.
207XX0004X — Orthopaedic Surgery of the Hand: specialists focused on hand, wrist, and forearm conditions and procedures.
207P00000X — Emergency Medicine Physician: physicians providing acute evaluation and management who may apply temporary or definitive casts in emergency settings.

Related Diagnoses

S52.501A — Unspecified fracture of the lower end of right radius, initial encounter for closed fracture

Clinical relevance: This distal radius fracture is an indication for immobilization with a hand and lower forearm gauntlet when fracture pattern and stability permit nonoperative casting.
S52.502A — Unspecified fracture of the lower end of left radius, initial encounter for closed fracture

Clinical relevance: Same relevance as S52.501A applied to the left side; supports billing of a left-sided gauntlet when appropriate.
S62.501A — Unspecified fracture of the right hand, initial encounter for closed fracture

Clinical relevance: Fractures within the hand may be managed with a gauntlet cast that immobilizes the metacarpals and wrist to control motion and promote healing.
S62.502A — Unspecified fracture of the left hand, initial encounter for closed fracture

Clinical relevance: Left-sided hand fractures managed nonoperatively are a clinical indication for a left-hand gauntlet cast.
M84.431A — Pathological fracture, right radius, initial encounter for fracture

Clinical relevance: Pathological fractures of the radius may require immobilization; documentation of the pathological etiology and laterality supports appropriate coding for cast application.

Related CPT Codes

CPT Code	Description	Relation to `29085`
`29065`	APPLICATION CAST SHOULDER TO HAND LONG ARM	Long-arm cast that extends from shoulder to hand; used for more proximal or extensive immobilization compared with the hand-and-lower-forearm gauntlet of `29085`. May be used instead of `29085` when immobilization of the elbow or humerus is required.

| 29075 | APPLICATION CAST ELBOW TO FINGER SHORT ARM | Short arm cast extending from elbow to fingers; represents an alternative level of immobilization when coverage of the elbow is necessary, compared with the more distal gauntlet (29085).

| 29086 | APPLICATION CAST FINGER | Application of a cast to an individual finger; used for more focal digital immobilization rather than the hand and lower forearm covered by 29085.

| 29055 | APPLICATION CAST SHOULDER SPICA | A shoulder spica cast is a more extensive immobilization involving the shoulder girdle; not commonly combined with 29085 but represents a different regional immobilization for more proximal injuries.

| 29058 | APPLICATION CAST PLASTER VELPEAU | Velpeau plaster cast immobilizes the shoulder and arm against the chest; an alternative for injuries requiring shoulder/arm immobilization rather than the localized hand/forearm gauntlet of 29085.

Clinical workflow notes:

29085 is selected when immobilization limited to the hand and lower forearm is appropriate.
Codes such as 29086 may be billed for isolated digital casts instead of 29085.
More extensive casts (29065, 29075, 29055, 29058) are alternatives when the injury requires proximal immobilization.

National Reimbursement Benchmarks

Medicare mean allowed rate ($110.43) is similar to BUCA (average commercial) mean ($114.94), with BUCA about $4.51 higher on a national basis. UnitedHealth Group and Cigna show the highest national mean rates at $150.19 and $144.46 respectively, while Aetna reports the lowest mean at $90.50.

Dispersion measured by the interquartile range (P75 − P25) is widest for UnitedHealth Group (approximately $87.12) and Cigna (about $83.20), indicating greater variability in paid amounts across providers. Dispersion is tightest for Medicare (about $12.00) and Aetna (about $43.00), showing more concentrated rate distributions for those payers.
