Other injury of heart without hemopericardium, subs encntr

This code signifies a follow-up encounter for an injury to the heart that does not involve bleeding into the pericardial sac. This could include contusions, lacerations, or other non-hemorrhagic damage to the cardiac muscle or structures. The patient is no longer in the initial phase of treatment for the injury.

Use this code for patients presenting for ongoing management, follow-up imaging, or evaluation of complications related to a previously diagnosed non-hemopericardial heart injury. This applies to encounters occurring after the initial treatment phase, but while the patient is still receiving active care for the injury.

• Requires an external cause code to fully describe the injury.
• Distinguish carefully from initial encounters (A) and sequela encounters (S).
• Ensure documentation clearly states "subsequent encounter" or indicates ongoing care for the injury.
