Hemarthrosis, left wrist

This code signifies the presence of blood within the joint space of the left wrist. This condition often results in pain, swelling, and limited range of motion in the affected wrist. It indicates an acute or chronic accumulation of blood within the synovial cavity.

Apply this code when documentation explicitly states hemarthrosis affecting the left wrist. This typically occurs following trauma, such as a fracture or ligamentous injury, or in patients with bleeding disorders or on anticoagulant therapy. Physician notes detailing a bloody aspirate from the left wrist joint or imaging confirming intra-articular hemorrhage support its use.

• Ensure laterality is clearly documented as "left wrist" to avoid incorrect coding.
• Always code any underlying cause of the hemarthrosis, such as a fracture or coagulation disorder, as a primary diagnosis if known.
• Differentiate from other forms of wrist effusion (e.g., M25.432 for effusion, left wrist) where blood is not specifically identified.
