Clinical & Coding Specifications
Clinical Context
An adult patient presents to an orthopedic urgent care or emergency department after a fall onto an outstretched hand with acute wrist pain, swelling, and deformity. Physical exam demonstrates point tenderness over the distal radius and limited wrist range of motion. Plain radiographs confirm a nondisplaced or minimally displaced distal radius fracture or a wrist sprain requiring immobilization. The clinician determines that a short arm fiberglass splint is appropriate for initial immobilization and applies the splint using Q4022 cast supplies (short arm splint, adult, fiberglass). The workflow includes assessment, informed consent, neurovascular check, preparation of the skin, application of stockinette and padding, placement of the fiberglass splint material, molding for proper alignment, trimming and securing, and post-application neurovascular and skin checks. Patient education is provided regarding elevation, icing, follow-up imaging, weight-bearing restrictions, signs of circulation compromise, and wound/skin care. Typical sites of service are emergency departments, orthopedic urgent care clinics, ambulatory surgery centers for minor procedures, and outpatient orthopedics clinics. The typical patient is age 11 years or older, ambulatory, and requires temporary immobilization while awaiting definitive treatment or fracture healing.
