What 69670 covers
An otolaryngologist performs this operation in a surgical setting to remove mastoid air cells affected by disease. It may be part of treatment for chronic mastoid infection or cholesteatoma. The operative report should identify the mastoid work performed and the condition prompting surgery; the code is not a label for a middle-ear repair alone.
Report the service for the documented mastoid air-cell removal, distinguishing a standalone mastoid operation from a procedure that includes tympanoplasty and mastoidectomy. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. For bilateral surgery, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose
- 69602Mastoid revision
- This code describes mastoid air-cell removal, while 69602 is for revision mastoidectomy with a complete-mastoidectomy result. The operative report should establish whether the surgery is a revision.
- 69604Mastoid revision
- 69604 is a revision mastoidectomy resulting in tympanoplasty. Use it for that revision circumstance rather than a standalone mastoid air-cell removal.
- 69641Tympanoplasty
- 69641 combines tympanoplasty and mastoidectomy. It is the closer fit when both middle-ear reconstruction and mastoid work are performed, rather than mastoid removal alone.
69670 billing questions
How is this code distinguished from revision mastoidectomy codes?
Use this code for the mastoid air-cell removal represented by the service. Codes 69602–69604 describe revision mastoidectomy situations, so the operative report must support revision rather than primary surgery.
Should this be reported separately with tympanoplasty and mastoidectomy?
When the operation includes tympanoplasty with mastoidectomy, consider the applicable combined tympanoplasty code, such as 69641 or 69642. Do not treat the mastoid work as a separate standalone service when it is part of that combined procedure.
What documentation supports reporting this service?
Document the indication, the mastoid air-cell work performed, and whether the operation was primary or a revision. The operative report should also make clear whether tympanoplasty was performed as part of the surgery.
What does the 90-day global period include?
The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral surgery handled?
For bilateral performance, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
CMS may pay an assistant at surgery for this procedure. Co-surgeons and team surgery are not permitted.
