What 69530 covers
An otolaryngologist, often an otologist, performs this extensive operation in a surgical facility to remove disease involving the mastoid and connected ear structures. It may be used for substantial chronic middle-ear disease or cholesteatoma when the operative work goes beyond a limited mastoidectomy. The operative report should identify the disease, the structures treated, and the full extent of the procedure; the diagnosis alone does not establish the appropriate code.
Select this code from the documented surgical work and distinguish it from less extensive mastoid procedures and other temporal-bone operations. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and other procedures are subject to the standard multiple-procedure reduction. For bilateral reporting, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose
- 69501Mastoidectomy
- This is a less extensive mastoidectomy option. Use 69530 only when the operative report supports the extensive service.
- 69502Mastoidectomy
- This is another mastoidectomy level. The operative extent, rather than the presence of mastoid disease alone, guides code selection.
- 69535Temporal bone surgery
- This describes removal of part of the temporal bone. It is a different service from extensive surgery centered on the mastoid.
69530 billing questions
How is this distinguished from a less extensive mastoidectomy?
Base the choice on the operative work and extent documented, not the diagnosis alone. The report should describe the structures treated and the scope of the mastoid operation.
Does the 90-day global period include related postoperative visits?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is this code handled when other 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. Document each distinct service performed.
How should bilateral surgery be reported?
Use modifier 50 for bilateral reporting; CMS pays the bilateral procedure at 150%.
Can an assistant or another surgeon be reported?
An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.
