D7340 — Vestibuloplasty — ridge extension (secondary epithelialization)
D7340 deepens the fold between lip and gum to give a denture more to hold on to, leaving the raw surface to heal on its own.
It is one of 18 codes covering other oral surgical procedures. For the procedure itself rather than the code, see the other oral surgical procedures guide; for the code, read on.
The sections below cover the conditions built into the code, what it tends to cost, what a dental plan is likely to pay, and where the line falls between this code and the ones next to it.
Told apart from the codes it is confused with
D7350 — Vestibuloplasty — ridge extension (including soft tissue grafts): It is the same procedure specified for including soft tissue grafts rather than for secondary epithelialization.
D7298 — Removal of temporary anchorage device [screw retained plate], requiring flap: It is the interim version.
D7297 — Corticotomy — four or more teeth or tooth spaces, per quadrant: It is that same corticotomy across four or more teeth in the quadrant.
D7296 — Corticotomy — one to three teeth or tooth spaces, per quadrant: It scores the bone around one to three teeth to speed up orthodontic movement through it.
D7340 sits in a group of 18 codes in total; the remainder are linked at the foot of this page. Where the codes sit this close together, the record of the appointment is what settles which one was earned. That is worth knowing before treatment rather than after.

These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.
Questions about D7340
D7340 — what is it?
It is the oral and maxillofacial surgery code for vestibuloplasty, ridge extension, secondary epithelialization, and it means that specific procedure and no other.
Is D7340 expensive?
Between $900–$2,400 in most practices — and that is the figure before any benefit is applied, not what you would pay at the desk.
How do dental plans handle D7340?
It is generally a covered benefit in the major oral surgery category, variable. Frequency limits and waiting periods are the usual reasons a claim is refused.
What is the difference between D7340 and D7350?
D7350 is vestibuloplasty, ridge extension, including soft tissue grafts: it is the same procedure specified for including soft tissue grafts rather than for secondary epithelialization. Because that is the only difference, a reviewer who disagrees with it simply reprices the claim to D7350 rather than refusing it.
