Multiple and unspecified open wound of lower limb, with tendon involvement

This code signifies an open wound affecting multiple sites or an unspecified location on the lower limb, where the injury extends to involve the tendons. This indicates a deeper, more complex wound than a superficial cut, impacting the structures responsible for movement.

Apply this code when documentation specifies an open wound of the lower limb with explicit mention of tendon involvement, and either multiple wound sites are present or the exact location is not specified. This is appropriate for traumatic injuries such as lacerations, punctures, or avulsions that penetrate to the tendon layer.

• Ensure documentation clearly states "tendon involvement" for the lower limb. Without this, a less specific open wound code should be used.
• If a specific lower limb site (e.g., foot, ankle, leg) and laterality are documented, a more precise code from the 891-893 series should be considered.
• Always sequence this code after any external cause of injury (E-code) if applicable.
