What 13100 covers
This service closes a short wound on the torso, such as the chest, abdomen, or back, when the repair requires more than routine layered closure. A physician or other qualified practitioner may perform it in an office, emergency department, or outpatient surgical setting after trauma, lesion removal, or another procedure. Complex work may include extensive undermining, debridement, scar revision, or retention sutures.
Select the code by the wound’s anatomic region, complexity, and repaired length; document the site, final length, and work supporting complex repair. The 10-day global period includes related postoperative visits during that period. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others are reduced. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this trunk repair.

13100 billing questions
How is this code distinguished from an intermediate repair?
Use this code when the trunk wound requires work beyond routine layered closure, not merely layered suturing. An intermediate repair code applies when layered closure is appropriate but the additional complexity criteria are not met.
What length qualifies for this code?
The repaired trunk wound must measure 1.1–2.5 cm. Document the final repair length and the anatomic site.
Can the repair be reported with a lesion excision?
A qualifying complex repair may be reported with an excision when the repair is separately reportable; routine closure is included in the excision. Document the complexity that supports separate reporting.
When is code 13102 reported?
Code 13102 is an add-on for additional repair length after an eligible primary complex repair code. It is not reported by itself.
Should modifier 50 be used for trunk wounds on both sides?
No. Medicare identifies bilateral adjustment as inappropriate for this code. Do not use modifier 50 to represent bilateral trunk repair.
Are postoperative visits separately paid during the global period?
Related postoperative visits during the 10-day global period are included in the procedure payment.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
