Code Description

ICD-10 S52.045 is a billable code used to indicate a diagnosis of nondisplaced fracture of coronoid process of left ulna.

Key Diagnostic Point:

A nondisplaced fracture of the coronoid process of the left ulna is a specific type of fracture that occurs at the bony prominence on the ulna, which is located at the elbow joint. This injury typically results from a fall onto an outstretched hand or direct trauma to the elbow. The coronoid process plays a crucial role in the stability of the elbow joint, and fractures in this area can lead to complications such as instability or limited range of motion. Although the fracture is classified as nondisplaced, meaning the bone fragments remain in alignment, it still requires careful evaluation and management to prevent further complications. Treatment often involves immobilization, physical therapy, and in some cases, surgical intervention may be necessary if there is associated instability or if the fracture does not heal properly. Understanding the implications of this fracture is essential for effective treatment and rehabilitation, as well as for accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Specificity of the fracture location (coronoid process)
  • Differentiation between displaced and nondisplaced fractures
  • Potential for associated injuries (e.g., ligamentous injuries)
  • Variability in treatment approaches (conservative vs. surgical)

Audit Risk Factors

  • Inadequate documentation of fracture type and location
  • Failure to document associated injuries or complications
  • Misclassification of displaced vs. nondisplaced fractures
  • Lack of follow-up documentation on treatment outcomes

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed imaging reports, surgical notes, and follow-up assessments are necessary to support the diagnosis and treatment plan.

Common Clinical Scenarios

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

Billing Considerations

Orthopedic surgeons must document the stability of the fracture and any associated injuries to ensure appropriate coding.

Physical Therapy

Documentation Requirements

Progress notes detailing range of motion, strength assessments, and rehabilitation goals.

Common Clinical Scenarios

Patients recovering from nondisplaced fractures undergoing rehabilitation to restore function.

Billing Considerations

Therapists should document the patient's response to therapy and any complications that arise during treatment.

Coding Guidelines

Inclusion Criteria

Use S52.045 When
  • According to ICD
  • 10 coding guidelines, S52
  • 045 should be used when the fracture is confirmed through imaging and is specifically identified as nondisplaced
  • It is important to document the mechanism of injury and any associated conditions
