Code Description

ICD-10 S42.12 is a billable code used to indicate a diagnosis of fracture of acromial process.

Key Diagnostic Point:

The acromial process is a bony projection of the scapula that forms the highest point of the shoulder. A fracture of the acromial process can occur due to trauma, such as a fall onto the shoulder or a direct blow to the area. This type of fracture is often associated with shoulder dislocations, humeral fractures, and rotator cuff injuries, as the acromion plays a critical role in shoulder stability and function. Patients may present with pain, swelling, and limited range of motion in the shoulder. Diagnosis typically involves physical examination and imaging studies, such as X-rays or MRI, to assess the extent of the fracture and any associated injuries. Treatment may vary from conservative management, including rest and physical therapy, to surgical intervention, particularly if there is significant displacement or involvement of the rotator cuff. Surgical options may include open reduction and internal fixation (ORIF) or arthroscopic repair, depending on the fracture's complexity and the patient's overall health status. Proper coding of this condition is essential for accurate billing and reimbursement, as well as for tracking outcomes in orthopedic care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture types and associated injuries
  • Need for precise documentation of fracture location and severity
  • Potential for co-existing shoulder conditions
  • Variations in treatment approaches (surgical vs. conservative)

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the type of fracture (e.g., displaced vs. non-displaced)
  • Lack of imaging reports to support the diagnosis
  • Improper linkage between diagnosis and treatment codes

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed operative reports, imaging studies, and post-operative notes are essential for accurate coding.

Common Clinical Scenarios

Fractures resulting from falls, sports injuries, or accidents requiring surgical intervention.

Billing Considerations

Documentation must clearly outline the fracture type, treatment plan, and any complications.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive assessments of functional limitations and rehabilitation progress.

Common Clinical Scenarios

Patients undergoing rehabilitation post-fracture or surgical repair.

Billing Considerations

Focus on documenting the impact of the fracture on daily activities and recovery goals.

Coding Guidelines

Inclusion Criteria

Use S42.12 When
  • According to ICD
  • 10 guidelines, S42
  • 12 should be used when the fracture is confirmed through imaging
  • It is important to document the specific location and type of fracture, as well as any associated injuries

Exclusion Criteria

Do NOT use S42.12 When
  • Exclusion criteria include fractures that are not specifically of the acromial process

Specialty Considerations

Orthopedic surgeons must document the relationship between the fracture and the rotator cuff injury.

Frequently Asked Questions

What are the common causes of an acromial process fracture?

Common causes include falls, direct trauma to the shoulder, and sports-related injuries. Patients with osteoporosis are at higher risk due to decreased bone density.
