Other bursal cyst, left wrist

This code signifies the presence of a non-inflammatory, fluid-filled sac (cyst) within a bursa of the left wrist, distinct from a ganglion cyst or other specified bursal conditions. These cysts typically arise from chronic irritation or trauma to the bursa, leading to fluid accumulation and palpable swelling.

Apply this code when documentation clearly identifies a bursal cyst located in the left wrist, and the provider has not specified it as a ganglion cyst or other specific bursal disorder. Supporting documentation should include physical exam findings noting a cystic mass, imaging reports (e.g., ultrasound, MRI) confirming a bursal cyst, and the specific anatomical location.

• Differentiate carefully between a bursal cyst and a ganglion cyst; ganglion cysts have distinct ICD-10-CM codes.
• Ensure the laterality (left wrist) is explicitly documented to support this specific code.
• Avoid using this code if the cyst is inflammatory (bursitis with cyst formation), as different codes apply for inflammatory conditions.
