Primary blast injury of rectum, subsequent encounter

This code signifies an injury to the rectum resulting from the direct impact of a blast wave, such as from an explosion. It specifically refers to the initial damage caused by the pressure wave itself, rather than secondary injuries from flying debris or burns.

This code is appropriate for follow-up care, subsequent treatments, or during the recovery phase of a patient who previously sustained a primary blast injury to the rectum. This includes situations like wound checks, medication management, or ongoing rehabilitation after the initial acute treatment has been completed.

• Ensure documentation clearly specifies "primary blast injury" to differentiate from other types of blast-related trauma.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always sequence this code after any codes for the specific type of rectal injury (e.g., laceration, contusion) if known and documented.
