Other bursal cyst, left shoulder

This code signifies a non-inflammatory, fluid-filled sac (cyst) located within a bursa of the left shoulder joint. It represents a distinct, often palpable, swelling that is not due to acute inflammation or infection of the bursa itself.

Use this code when documentation specifies a bursal cyst affecting the left shoulder, differentiating it from bursitis or other shoulder pathologies. Supporting documentation should clearly state "bursal cyst" and specify the left shoulder, often confirmed by imaging studies like ultrasound or MRI.

• Ensure documentation explicitly states "cyst" and not just "bursitis" to avoid miscoding.
• Verify laterality (left shoulder) is clearly documented; separate codes exist for the right and bilateral shoulders.
• Do not use this code for inflammatory conditions of the bursa (bursitis), which are classified under M70.- or M71.0-.
