Code Description

ICD-10 S82.046 is a billable code used to indicate a diagnosis of nondisplaced comminuted fracture of unspecified patella.

Key Diagnostic Point:

A nondisplaced comminuted fracture of the patella occurs when the patella, or kneecap, is broken into multiple pieces but remains in its normal anatomical position. This type of fracture is often the result of direct trauma to the knee, such as a fall or a sports injury. Unlike displaced fractures, where the bone fragments are misaligned, nondisplaced fractures typically do not require surgical intervention unless there are complications. Symptoms may include localized pain, swelling, and difficulty in knee extension. Diagnosis is usually confirmed through imaging studies such as X-rays or CT scans. Treatment often involves conservative management, including rest, ice, compression, elevation (RICE), and physical therapy to restore function and strength. In some cases, if the fracture does not heal properly, surgical options may be considered to stabilize the patella. Understanding the nuances of this injury is crucial for accurate coding and appropriate management.

Frequently Asked Questions

What is the difference between a nondisplaced and displaced fracture?

A nondisplaced fracture means the bone is broken but remains in its normal position, while a displaced fracture involves misalignment of the bone fragments.
