Neurosurgery
About 61345: Other posterior fossa cranial decompression
Reports cranial surgery to decompress the posterior fossa when the operative service is not described by a more specific decompression code.
A neurosurgeon performs an open cranial procedure to relieve pressure or crowding in the posterior fossa, the space containing the cerebellum and brainstem. The operation involves removing cranial bone to create room for the affected structures. It is performed in an operating room, typically in a hospital, for a documented posterior fossa decompression that does not fit a more specifically defined procedure, such as a named suboccipital decompression.
Select the code from the operative report’s documented site and work, not from the diagnosis alone. Documentation should identify the posterior fossa and explain the decompressive procedure performed. CMS 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 procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61345 billing questions
How does this differ from 61343?
Use 61343 when the documented procedure is the specifically described suboccipital decompression of the medulla or spinal cord. This code is for another posterior fossa decompression not captured by that more specific service.
Can the diagnosis alone support this code?
No. The operative report should establish that a posterior fossa decompression was performed and describe the work sufficiently to distinguish it from a more specifically defined procedure.
Are related postoperative visits included?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other same-session procedures paid?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
