What 69635 covers
An otologic surgeon uses this code for tympanoplasty performed together with mastoidectomy, including associated canal and middle-ear work and repair of the tympanic membrane. The operation may be used for chronic middle-ear disease, such as disease involving the mastoid, when the surgeon repairs the eardrum but does not reconstruct the ossicular chain. It is typically performed in an operating room under anesthesia.
Choose this code when the operative report supports both tympanoplasty and mastoidectomy and documents no ossicular chain reconstruction; a tympanoplasty without mastoidectomy belongs to a different code family. The report should identify the treated ear, surgical extent, and whether the ossicles were reconstructed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

69635 billing questions
How does this differ from 69631?
69635 includes mastoidectomy with tympanoplasty. 69631 is the tympanoplasty option without mastoidectomy.
When would 69636 be considered instead?
Use the applicable sibling code when the operation includes ossicular chain reconstruction. This code is for tympanoplasty with mastoidectomy without that reconstruction.
Can the eardrum repair and mastoidectomy be billed separately?
The tympanoplasty code includes the associated tympanic membrane repair and middle-ear work in the operation. Do not separately report those included elements as independent procedures.
What documentation supports reporting 69635?
The operative report should establish that tympanoplasty and mastoidectomy were performed, describe the surgical extent, and clarify that the ossicular chain was not reconstructed.
How are bilateral procedures and additional same-session procedures paid?
CMS pays bilateral reporting with modifier 50 at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%.
Can an assistant surgeon or co-surgeon be reported?
CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
