It can be only reported when done alone or any unrelated done in combination with CPT 49000.

The appropriate modifier will be required when done in conjunction with other procedures.

For example, if a patient got a gunshot wound and physicians have done exploration of the wound without Laparotomy due to penetrating wound, then CPT 20102 would be reported instead of CPT 49000.

If any recent laparotomy was done of the patient and required reopening, CPT 49002 will be reported instead of 49000. CPT 49010 will be billed for the exploration of the peritoneal organs.

  • Exploratory Laparotomy
  • Exploratory Celiotomy
  • With or without biopsy

CPT 49002 will be reported when reopening recently Laparotomy done. It is normally reopened to treat bleeding or post-operative infection at the existing laparotomy site.
