Traumatic hemopneumothorax, subsequent encounter

This code signifies the presence of both blood and air in the pleural space due to a traumatic injury, specifically during the healing or recovery phase. It indicates that the initial injury has already been treated, and the patient is now receiving follow-up care for this condition.

Apply this code for patients presenting for subsequent treatment, monitoring, or evaluation of a traumatic hemopneumothorax after the initial acute care has concluded. This includes scenarios such as follow-up appointments for chest tube management, imaging to assess resolution, or ongoing pain management related to the initial injury.

• Ensure documentation clearly specifies "subsequent encounter" for the hemopneumothorax.
• Always code the underlying traumatic injury that caused the hemopneumothorax first.
• Do not use this code for the initial acute presentation of the hemopneumothorax.
