Pnctr w/o fb of low back and pelv w penet retroperiton, subs

This code signifies a puncture wound to the lower back or pelvic region that has extended deep enough to breach the retroperitoneal space, but without any foreign object remaining in the wound. The "D" suffix indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for an injury that has already received initial treatment.

Use this code for patients presenting for ongoing management, wound care, or evaluation of complications related to a previously treated puncture wound of the lower back or pelvis that involved retroperitoneal penetration. This applies after the initial acute care for the injury has been rendered.

• Ensure documentation clearly states "subsequent encounter" or similar for ongoing care.
• Verify the wound location is specifically lower back or pelvis and that retroperitoneal penetration is confirmed.
• Confirm the absence of a retained foreign body; if present, a different code would be required.
