Prepatellar bursitis, right knee

This code identifies inflammation of the prepatellar bursa located anterior to the patella in the right knee. This condition, often referred to as "housemaid's knee," typically results from repetitive kneeling or direct trauma to the front of the knee.

Assign this code for a documented diagnosis of prepatellar bursitis affecting the right knee. Documentation should clearly specify the location (right knee) and the nature of the condition (bursitis). This code is appropriate for both acute and chronic presentations.

• Ensure laterality is clearly documented (right vs. left) to avoid using an unspecified code.
• Distinguish from other knee bursitides (e.g., infrapatellar, anserine) which have different codes.
• If an underlying cause (e.g., infection, crystal deposition) is identified, sequence that code first if it meets the definition of the principal diagnosis.
