D7910 is the CDT code for the suturing of a recent, small wound up to 5 cm in length — simple closure of a fresh laceration in or around the mouth that does not require complex, layered repair. It applies to straightforward primary closure of a recent wound, most often from minor trauma.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D7910 Code
Report D7910 when a dentist or oral surgeon performs simple suture closure of a recent wound up to 5 cm — for example, a minor soft-tissue laceration of the lip, cheek, or tongue from accidental trauma. The wound is fresh, relatively clean, and closed with straightforward sutures rather than a layered or reconstructive repair.
Match the code to wound size and complexity. D7910 is simple repair, up to 5 cm. Complicated suturing of small wounds (up to 5 cm) involving careful coordination of tissue layers is reported with D7911, and larger complicated wounds (over 5 cm) with D7912. Do not report D7910 for routine closure that is incidental to another procedure — for instance, the flap closure that is part of a surgical extraction is already included in that surgery and is not separately billable.
Documentation & Clinical Scenarios
Wound-repair claims depend on showing a discrete, recent injury and a simple closure, so the chart should capture:
- Wound location and length (in centimeters) to support the up-to-5-cm threshold.
- Mechanism and timing — how and when the injury occurred (a recent wound).
- Repair detail — that closure was simple/primary, the number of sutures, and the material used.
- A narrative confirming the suturing was a distinct procedure, not closure incidental to another surgery.
When the wound results from trauma, the visit may also involve other separately reported services (imaging, an emergency exam); each is documented and billed under its own code.
Insurance & Billing Tips
- Confirm it isn't incidental. Suturing that is part of another surgical procedure in the same site is generally not separately payable; D7910 is for a distinct wound repair.
- Document length and timing. The "recent" and "up to 5 cm" criteria matter; record both so the simple-repair code is supported.
- Pick the right complexity code. Use D7911 or D7912 for complicated or larger wounds rather than forcing D7910.
- Consider medical coverage for trauma. Traumatic laceration repair sometimes routes to medical benefits; verify where to file.
- Keep a clear narrative for appeals. A concise description of the injury and closure supports the claim if questioned.
Example Case
A teenager arrives after a sports injury with a clean, roughly 2 cm laceration of the lower lip that happened an hour earlier. The dentist cleans the wound, confirms it is a simple, recent laceration, and closes it with a few sutures. The repair is reported as D7910, with the wound length and mechanism documented in the note. Because the closure was a distinct, simple repair and not incidental to another procedure, and the chart supported the criteria, the claim processes cleanly.

Frequently Asked Questions
How is D7910 different from D7911 and D7912?
All three cover suturing wounds, but they differ by complexity and size. D7910 is simple closure of a recent wound up to 5 cm. D7911 is complicated suturing of a wound up to 5 cm — closure requiring careful coordination of tissue layers. D7912 is complicated suturing of a wound over 5 cm. Choosing the code that matches the actual repair and length is essential; over- or under-stating complexity is a common reason for denials or down-coding.
Is suturing after an extraction billed separately with D7910?
Usually no. Closure that is incidental to another surgical procedure — such as the flap sutures placed as part of a surgical extraction — is already included in that procedure's code and is not separately reportable as D7910. D7910 is intended for a distinct repair of a separate, recent wound, not for the routine closure that any surgery includes.
Will insurance cover suturing of a small wound?
Coverage varies, and traumatic wound repair sometimes falls under medical rather than dental benefits. Plans are more likely to pay when the note documents a recent, distinct laceration, its length, and a simple closure. Verify benefits and confirm whether the claim should go to the medical or dental plan, and keep a clear narrative in case the claim is reviewed.
Does D7910 require pre-authorization?
Because suturing is typically performed urgently after an injury, pre-authorization is usually impractical and not generally required. The priority is solid documentation at the time of service — wound length, timing, mechanism, and a simple closure — so the claim stands on its own. That contemporaneous record also supports an appeal if a payer later questions the repair.
