Hemarthrosis, right hand

This code signifies the presence of blood within the joint space of the right hand. It indicates an intra-articular hemorrhage, which can result from trauma, bleeding disorders, or other underlying conditions affecting the joint.

Apply this code when documentation explicitly states hemarthrosis affecting the right hand. This typically occurs following a traumatic injury, such as a fracture or severe sprain, or in patients with coagulopathies. Supporting documentation should clearly specify the location as the right hand.

• Ensure laterality is accurately documented and coded; differentiate from left hand (M25.042) or unspecified hand (M25.049).
• Always code the underlying cause of the hemarthrosis, such as a fracture or bleeding disorder, as the primary diagnosis if known.
• Do not confuse with other joint effusions (M25.4x) or synovial hypertrophy (M25.3x) unless blood is explicitly documented.
