What 41805 covers

This service covers removal of a retained foreign object located in gingival tissue. It is typically performed by an oral and maxillofacial surgeon or another clinician qualified to treat the gum, in an office or facility setting. The operative target is the object in the gum; an object located in jawbone is coded separately. The record should establish the object’s gingival location and describe the removal performed.

Report the code for the gum foreign-body removal, not for drainage of a gum lesion or excision of gum tissue when those are the actual services. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documentation of 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.

How to choose

41800 describes drainage of a gum lesion. Choose 41805 when the service removes a foreign object from the gum.
41822Excision of gum lesion
41822 is for excision of a gum lesion, not removal of a retained foreign object from gingival tissue.

41805 billing questions

How do I distinguish this from removal of a foreign body from jawbone?

Use 41805 when the retained object is in gingival tissue. Use 41806 when the object is located in jawbone.

Is drainage of a gum lesion included?

This code represents removal of a foreign object, not drainage of a gum lesion. Code 41800 describes drainage when that is the service performed.

What documentation supports reporting this code?

Document the foreign object, its location in gingival tissue, and the removal performed. Make the location clear enough to distinguish gum from jawbone.

Are postoperative visits separately reported during the global period?

Related postoperative visits for 10 days are included in the procedure’s global period.

Can modifier 50 be reported?

No. Bilateral adjustment does not apply because modifier 50 is inappropriate for this descriptor and anatomy.

When may an assistant-at-surgery be paid?

Assistant-at-surgery payment is allowed only when the record documents medical necessity. Co-surgeons and team surgery are not permitted.
