Explosion of explosive gases, subsequent encounter

This code signifies a patient presenting for follow-up care related to injuries sustained from an explosion of explosive gases. It indicates that the initial acute phase of treatment has passed, and the patient is now receiving ongoing management, rehabilitation, or monitoring for complications. This could include addressing burns, blast injuries, or other sequelae from the initial event.

Use this code for any subsequent encounter where the patient is being treated for the direct effects or complications of an explosion of explosive gases. This applies to follow-up appointments for wound care, physical therapy, psychological support, or evaluation of long-term damage. It should be used after the initial acute care for the injury has been coded with the appropriate initial encounter code.

• Always pair with an external cause code (V00-Y99) to specify the circumstances of the explosion.
• Ensure the specific injury(ies) resulting from the explosion are also coded.
• Verify the encounter type (initial, subsequent, sequela) to select the correct 7th character.
