Code Description

ICD-10 S42.146 is a billable code used to indicate a diagnosis of nondisplaced fracture of glenoid cavity of scapula, unspecified shoulder.

Key Diagnostic Point:

A nondisplaced fracture of the glenoid cavity of the scapula refers to a break in the bone that does not result in the separation of the bone fragments. The glenoid cavity is the shallow socket in the scapula that articulates with the head of the humerus, forming the shoulder joint. Such fractures can occur due to trauma, such as falls or direct blows to the shoulder, and may be associated with shoulder dislocations or rotator cuff injuries. 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 confirm the fracture and assess any associated injuries. Treatment may vary from conservative management, including rest and physical therapy, to surgical intervention if there are complications or if the fracture affects shoulder stability. Accurate coding is essential for proper reimbursement and to reflect the complexity of the injury and its management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and associated injuries
  • Need for precise documentation of fracture type and location
  • Potential for concurrent shoulder conditions (e.g., dislocations, rotator cuff tears)
  • Differentiation from other shoulder injuries

Audit Risk Factors

  • Inadequate documentation of the fracture type
  • Failure to document associated injuries
  • Incorrect coding of the shoulder as 'unspecified'
  • Lack of imaging reports to support the diagnosis

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

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

Common Clinical Scenarios

Fractures resulting from sports injuries, falls, or accidents.

Billing Considerations

Documentation must clearly indicate the fracture type and any associated procedures performed.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive assessments of functional limitations and rehabilitation plans.

Common Clinical Scenarios

Patients undergoing rehabilitation post-fracture or surgery.

Billing Considerations

Focus on functional outcomes and progress notes to support ongoing treatment.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding fractures, including nondisplaced fractures of the glenoid cavity. This specificity aids in better tracking of treatment outcomes and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding fractures, including nondisplaced fractures of the glenoid cavity. This specificity aids in better tracking of treatment outcomes and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding fractures, including nondisplaced fractures of the glenoid cavity. This specificity aids in better tracking of treatment outcomes and resource allocation.

Frequently Asked Questions

What is the difference between a displaced and nondisplaced fracture?

A displaced fracture involves a separation of the bone fragments, while a nondisplaced fracture means the bone cracks but maintains its proper alignment.
