Overview of CPT Code 23505: Closed treatment of humeral shaft fracture
CPT Code 23505 refers to the closed treatment of a fracture in the humeral shaft, which is the long bone of the upper arm. This procedure is typically performed without surgical incision and aims to realign the fractured bone segments to promote healing.
When CPT Code 23505 is Used?
This code is applicable in various clinical scenarios, including:
- Acute humeral shaft fractures due to trauma or falls.
- Fractures that are stable and can be treated without surgical intervention.
- Patients who are not surgical candidates due to comorbidities.

Patients may present with the following symptoms:
- Severe pain in the upper arm.
- Swelling and bruising around the fracture site.
- Inability to move the arm or shoulder.

Understanding the causes and risk factors can help in prevention and management.
- High-impact trauma such as car accidents or falls.
- Sports injuries, particularly in contact sports.
- Osteoporosis or other conditions that weaken bones.
Diagnostic Tests Before Procedure
To confirm the diagnosis and plan treatment, the following tests may be performed:
- X-rays to visualize the fracture and assess alignment.
- CT scans for detailed imaging if the fracture is complex.
- MRI in cases of suspected soft tissue injury.
Procedure Description
The closed treatment procedure involves several key steps:
- Patient is positioned comfortably, and the arm is exposed.
- The physician assesses the fracture and may manipulate the arm to realign the bone.
- Once aligned, a splint or cast is applied to immobilize the arm.
- Follow-up imaging may be done to ensure proper alignment.

Patients should follow these steps to prepare for the procedure:
- Inform the physician of any allergies or medications.
- Avoid eating or drinking for a specified period before the procedure.
- Arrange for transportation home post-procedure.
Recovery and Aftercare
Post-procedure recovery typically includes:
- Wearing a splint or cast for several weeks as directed.
- Regular follow-up appointments to monitor healing.
