Other bursal cyst, left hip

This code describes a non-inflammatory, fluid-filled sac (cyst) located within a bursa around the left hip joint. These cysts are typically benign and can arise from chronic irritation, trauma, or degeneration of the bursa, leading to localized swelling and sometimes pain.

Use this code when documentation specifies a bursal cyst affecting the left hip, without evidence of inflammation or infection. This diagnosis is often made based on physical examination findings and confirmed by imaging studies such as ultrasound or MRI. The physician's notes should clearly indicate the laterality and the cystic nature of the bursal lesion.

• Ensure documentation explicitly states "left hip" and "bursal cyst" to support this specific code.
• Differentiate from bursitis (M70.- series) which implies inflammation, or other types of cysts (e.g., ganglion cyst).
• If laterality is unspecified, an unspecified code (e.g., M71.359) would be more appropriate.
