unlisted codes will not get the reimbursement you deserve, I very well know. This is hard to get approval for and it has to be in the patients benefits. When calling you must be specific that this is dental extractions. I work for an ASC and we never rely on the dental surgeon's office for this information. The unlisted code, 41899, is all that can be used IF, and I repeat IF this is done in an ASC. Medicare as all knows this is a no no. These procedures if done in an ASC should be self pay. Routine dental extractions, full mouth...self pay, regardless, any insurance.
However, there are times when a patient has been in a car accident, and IF covered under their benefits can be done. You must make the rep dig for this. Excising a tooth or teeth to remove a plate placed due to a previous car accident, the surgeon must remove the tooth or teeth to remove. You must use good judgement on these cases. I also suggest to keep from the hassle and possible denial don't do. NEVER RELY ON THE OFFICE FOR THE INFORMATION...CALL YOURSELF.
If ever in doubt talk to your office manager or administrator for direction on these cases BEFORE they are done. YOUR BEST RESOURCE.
