What 40845 covers

This service reconstructs the floor of the mouth using a bone graft. Oral and maxillofacial surgeons and other surgeons qualified in oral reconstruction typically perform it in a hospital operating room or outpatient surgical setting. The operative report should identify the site, reconstructive work, and bone graft used, rather than describing only lesion removal or closure of an acute wound.

Select 40845 when the reconstruction uses a bone graft; codes 40840–40844 distinguish other approaches by the extent of reconstruction and whether a skin graft is used. Medicare coverage is restricted to specific circumstances, so documentation should support the indication and work performed. The 90-day global period includes the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

40845 billing questions

How does 40845 differ from 40840–40844?

40845 is for floor-of-mouth reconstruction using a bone graft. The other codes distinguish reconstruction extent and whether a skin graft is used; select the code that matches the documented technique.

Can this code be used for excision of a mouth lesion?

No. Lesion removal alone is not reconstruction with a bone graft. Report the code that describes the documented lesion excision when that is the service performed.

What documentation supports reporting 40845?

The operative report should identify the floor-of-mouth site, reconstructive work, and bone graft. It should also support the clinical indication.

Can modifier 50 be reported?

No. The descriptor and anatomy make modifier 50 inappropriate for this service.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures are subject to the standard 50% multiple-procedure reduction.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

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.
