Other bursal cyst, left elbow

This code represents a non-inflammatory, fluid-filled sac (cyst) located within or adjacent to a bursa in the left elbow. These cysts are typically benign and may arise from chronic irritation, trauma, or degenerative changes, distinct from acute bursitis.

Use this code when documentation explicitly identifies a bursal cyst affecting the left elbow, without evidence of acute inflammation or infection. This diagnosis is often supported by imaging studies (e.g., ultrasound, MRI) confirming the cystic nature and location, along with a physical examination.

• Ensure laterality is clearly documented as "left elbow" to support this specific code.
• Differentiate from acute bursitis (M70.322) or other specific types of bursitis.
• If the cyst is ruptured, consider additional codes for the complication.
