What 69603 covers

An otolaryngologist or otologist reports this service when revising a previously operated mastoid and the completed procedure results in a radical mastoidectomy. It is associated with complex ear disease, such as persistent or recurrent cholesteatoma, when the surgeon must revise the mastoid cavity and establish the radical surgical result. The operative report should describe the prior mastoid surgery, the work performed, and the resulting anatomy and extent of the revision.

Select this code based on the final operative result, not the diagnosis alone; a revision ending in a different mastoidectomy result belongs to a different code in the revision series. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment 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.

69603 billing questions

What distinguishes this code from 69601 or 69602?

Choose among the revision codes according to the resulting mastoidectomy: 69601 represents a complete mastoidectomy result, 69602 a modified radical result, and 69603 a radical result.

How is 69603 distinguished from 69604?

Use 69603 when the revision results in a radical mastoidectomy. Use 69604 when the revision results in tympanoplasty instead.

What documentation supports reporting 69603?

Document the prior mastoid operation, the revision work performed, and the final surgical result establishing a radical mastoidectomy. The diagnosis by itself does not establish the appropriate revision code.

Does the 90-day global period include postoperative visits?

Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral surgery reported?

When the procedure is performed bilaterally, modifier 50 is paid at 150%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
