What 11740 covers
This service relieves pressure from blood trapped beneath a fingernail or toenail, commonly after a crush injury or direct blow. The clinician makes a small opening through the nail plate and drains the hematoma; the nail plate is generally left in place. Physicians and podiatrists may perform the procedure in an office, urgent care clinic, or emergency department when the nail injury is appropriate for drainage.
Report 11740 when the documented service is evacuation of a subungual hematoma, not nail-plate removal, nail-bed repair, or routine nail care. The record should identify the injured nail, the traumatic hematoma, and the drainage performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery services are not paid, and co-surgeons and team surgery are not permitted.

11740 billing questions
When should 11740 be used instead of 11730?
Use 11740 for draining blood beneath the nail while leaving the nail plate in place. Use 11730 when a simple nail-plate avulsion is performed.
Can nail-bed repair also be reported?
A separate nail-bed laceration repair may be reported when it is actually performed and documented; evacuation alone is not nail-bed repair.
Should modifier 50 be appended for matching nails?
No. CMS identifies bilateral adjustment as inapplicable to 11740, and modifier 50 is inappropriate.
What same-day care is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care for the evacuation.
How does the multiple procedure rule affect 11740?
When procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple procedure reduction.
