Summary & Overview
HCPCS Q4010: Cast Supplies, Short Arm Fiberglass
HCPCS Level II code Q4010 identifies fiberglass short arm cast supplies for adults and adolescents aged 11 and older. This supply code is used when providers apply or supply a short arm fiberglass cast for upper extremity immobilization. Nationally, supply codes such as Q4010 matter because they standardize billing for commonly used orthopedic materials and influence reimbursement workflows across inpatient and outpatient sites of service.
Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for short arm fiberglass casts, typical sites of service where the code is billed, and which national payers commonly process the code. The report highlights benchmark considerations, billing nuances for supply versus procedure reporting, and areas where policy updates or payer-specific edits may affect claims processing.

Clinical & Coding Specifications
Clinical Context
An adult patient (age 18+) presents to an orthopedics clinic or urgent care after a distal radius fracture sustained during a fall. The patient reports wrist pain, swelling, and limited range of motion. Clinical workflow: history and focused physical exam, point-of-care X‑rays confirming a non-displaced or minimally displaced short arm fracture of the forearm/wrist; treatment plan includes closed reduction if needed followed by immobilization in a short arm fiberglass cast. Cast supplies billed under Q4010 are furnished during the same visit. The procedure is commonly performed in ambulatory surgery centers, physician offices, urgent care centers, and emergency departments. Follow-up visits are scheduled for cast checks and potential radiographic reassessment within 1–2 weeks; cast removal and transition to a brace or physical therapy occur based on healing and clinical progress.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When reporting only the physician professional component associated with a separately payable service performed by another entity during cast application (e.g., reading radiographs) |
59 | Distinct procedural service | When a separately identifiable service distinct from the cast supply occurs on the same day (for example, closed reduction plus cast application) |
52 | Reduced services | When a shortened or partially reduced cast application service is performed and the full service is not rendered |
53 | Discontinued procedure | When cast application is started but discontinued due to an emergent change in the patient’s condition |
76 | Repeat procedure by same provider | When a repeat cast application is performed by the same provider during the same episode (use 76 if applicable) |
77 | Repeat procedure by another provider | When another provider repeats the cast application or supplies during the global period |
RT | Right side | When the cast is applied to the right upper extremity |
LT | Left side | When the cast is applied to the left upper extremity |
59 | Distinct procedural service | When an unrelated service is performed at a separate anatomic site on the same day (used sparingly) |
XE | Separate encounter, a different encounter | When services are provided in a separate encounter (note: non-listed; use payer-specific guidance) |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RP0000X | Orthopaedic Surgery | Commonly applies to physicians who apply casts and manage fractures |
103K00000X | Emergency Medicine | Applies to emergency physicians performing acute immobilization and initial fracture management |
2080P0208X | Physical Medicine & Rehabilitation | Applies when PM&R physicians manage casting during fracture care or follow-up |
261QM0800X | Family Medicine | Applies to family physicians in urgent care or office settings providing cast application |
3336C0002X | Orthopedic Casting Technician | Applies to allied health professionals trained in cast application and supply handling |
