Hemarthrosis, other specified site

This code signifies the presence of blood within a joint cavity, specifically when the affected joint is not one of the commonly specified sites (e.g., knee, hip, shoulder, ankle, elbow, wrist, hand, foot). It indicates an accumulation of blood that can result from trauma, bleeding disorders, or other underlying medical conditions.

Use this code when documentation clearly states hemarthrosis in a joint not covered by more specific codes, such as the temporomandibular joint, sternoclavicular joint, or sacroiliac joint. Supporting documentation should include a physician's diagnosis of hemarthrosis and the specific "other" joint involved.

• Ensure the documentation explicitly identifies the joint as "other specified" and not one with a more precise code.
• Always code the underlying cause of the hemarthrosis (e.g., trauma, coagulopathy) first, if known and applicable.
• Avoid using this code if a more specific ICD-10-CM code exists for the documented joint.
