D7962 is the CDT code for a lingual frenectomy, the surgical removal of the band of tissue tethering the underside of the tongue, most often performed to release a tongue-tie that restricts tongue movement.
The billing decision on a tongue-tie release usually comes before the code: dental plan or medical plan. An infant release for feeding difficulty is frequently a medical claim under CPT with an ankyloglossia diagnosis, while an older child or adult treated in a dental operatory typically bills D7962 to the dental plan. Getting that routing wrong wastes the stronger benefit, and some dental plans will not consider the claim until the medical carrier has ruled.
What D7962 covers
D7962 reports the excision of the lingual frenum, the band of tissue connecting the underside of the tongue to the floor of the mouth. When that band is short, tight, or attached too far forward, it restricts tongue elevation and extension: the tongue-tie. The release removes the restricting band so the tongue can move normally. The code is site-specific and carries no arch designation; the lingual frenum is the site.
It does not cover:
- A frenectomy on the lip or cheek side. That is D7961.
- Excision combined with repositioning of the underlying muscle and a z-plasty or other local flap closure. That is D7963, the frenuloplasty, and tongue-tie cases closed with a plasty belong there.
- Anything billed as D7960. The old single frenulectomy code was deleted effective January 1, 2021; see the D7960 page.
The medical-versus-dental routing question
Tongue-tie is the frenectomy family’s strongest medical crossover, and for infants it is often the primary route. A newborn or infant whose tongue-tie interferes with feeding is being treated for a functional medical problem, and medical plans commonly cover the release when the record documents the feeding difficulty, frequently with input from a lactation consultant or pediatrician.
On the medical claim, the diagnosis is Q38.1, ankyloglossia, and the procedure code follows the technique: CPT 41010 for an incision-type release of the lingual frenum (frenotomy) and CPT 41115 for excision of the frenum. A frenoplasty maps to CPT 41520. The lip-side CPT codes (40806, 40819) are not appropriate for tongue-tie; they report the labial/buccal site.
How far this route works is plan-dependent. Some medical plans cover infant releases readily and adult releases only with documented functional impairment such as speech or swallowing problems. Some restrict which provider types they credential for it. And some dental plans coordinate, requiring a medical denial before they will consider D7962. Verify both benefits before the appointment rather than picking a lane by habit.
D7962 versus D7963 on a tongue-tie
Not every tongue-tie release is a frenectomy. When the surgeon excises the frenum and closes with a z-plasty or another local flap, repositioning tissue rather than simply removing the band, the procedure is a frenuloplasty and the code is D7963. That closure choice is common in older children and adults where the release is deeper and primary closure would re-tether.
The operative note decides this. “Frenum excised, site closed” supports D7962. “Frenum excised, horizontal releasing incisions, z-plasty closure” supports D7963. Billing D7962 for a plasty-closed case undercodes the work; billing D7963 without a documented plasty invites a downgrade on review.
Why D7962 claims get denied
- No functional documentation. A tight frenum by itself reads as an anatomical variant. Carriers look for the consequence: feeding difficulty in infants, documented speech articulation problems, restricted tongue mobility affecting hygiene or a prosthesis. Chart the impairment along with the anatomy.
- Plan exclusion or age limits. Some dental plans exclude frenum surgery entirely, and some medical plans limit coverage past infancy. This is contract language, not appealable clinical judgment, so it belongs in the pre-treatment verification call.
- Wrong route first. Submitting D7962 to a dental plan that coordinates behind medical, or a medical claim to a plan that considers it dental-in-nature, produces a denial that is really a routing instruction. Read the denial reason before rewriting the claim.
- Deleted-code rejection. A claim carrying D7960 for a current date of service rejects as invalid regardless of coverage.
Documentation that supports the claim
- The restriction: tongue elevation and extension findings, appearance and attachment of the frenum.
- The functional impairment: feeding notes for infants (weight, latch difficulty, provider referrals), speech or mobility findings for older patients.
- The procedure: technique, instrument, whether tissue was excised or incised, and the closure. This is also what separates D7962 from D7963 and, on medical claims, 41115 from 41010.
- The referral chain when one exists. A pediatrician, ENT, or lactation-consultant referral strengthens medical necessity on either claim type.
Setup and verification checklist
- Verify both benefits on tongue-tie cases before scheduling. The medical-first question decides the claim, the fee, and the patient conversation.
- Keep D7962 and D7963 as separate, plainly labeled line items so the biller matches the code to the documented closure, not to habit.
- Purge D7960 from templates and fee schedules. It has been invalid since January 1, 2021.
- Build a documentation prompt for functional findings. The impairment sentence is the difference between a covered release and an elective-procedure denial on many plans.
FAQs
- What is the dental code for tongue-tie release?
- D7962, the lingual frenectomy, when the release is done by excising the frenum and the claim goes to a dental plan. If the tissue is repositioned with a z-plasty or similar flap closure rather than simply excised, the code is D7963, frenuloplasty. Many tongue-tie cases, especially infants treated for feeding difficulty, are billed to the medical plan instead, using CPT codes with the ankyloglossia diagnosis Q38.1.
- Should a tongue-tie release be billed to medical or dental insurance?
- It depends on the patient and the plans. Infant releases tied to documented feeding problems are commonly covered under the medical benefit, billed with CPT 41010 for an incision-type release (frenotomy) or 41115 for excision of the frenum, linked to diagnosis Q38.1, ankyloglossia. Dental plans typically handle the same procedure as D7962. Verify both benefits before treatment: some dental plans exclude the procedure, some medical plans restrict it by age or provider type, and coordination rules differ by contract.
- Why is a tongue-tie release D7962 and not D7961?
- Because the code follows the site of the frenum. D7962 removes the lingual frenum, the band under the tongue. D7961 removes a buccal or labial frenum, the bands on the cheek or lip side. Both replaced the deleted catch-all code D7960 in 2021, which is why an old template can still surface the wrong code.
- Does using a laser change the code for a lingual frenectomy?
- No. The code reports the procedure, not the instrument. A lingual frenectomy performed with a laser, electrosurgery, or a blade is still D7962. What can change the code is the technique on the tissue: a simple incision to release (frenotomy) versus excision, and on the medical side those map to different CPT codes, 41010 versus 41115. On the dental claim, document what was done to the frenum and code accordingly.
