What 61107 covers

This service involves making a small twist-drill opening in the skull and placing a ventricular catheter through it to provide drainage. Neurosurgeons commonly use it for temporary cerebrospinal-fluid diversion or pressure management, such as acute hydrocephalus or ventricular blood obstructing normal CSF flow. It is generally performed in a hospital or other facility setting, with catheter drainage often managed in an intensive care or neurosurgical unit.

Report 61107 when the documented access is twist-drill and the procedure includes placement of a ventricular drainage catheter. Select a subdural drainage or hematoma-evacuation code when that is the procedure instead; a burr-hole approach has different code selection. The operative note should identify the opening technique, ventricular target, catheter placement, and drainage purpose. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

How to choose

61105Twist-drill punctureHematoma drainage
Use 61107 when a ventricular drainage catheter is implanted through twist-drill access. 61105 describes a different twist-drill drainage service, such as drainage directed to a subdural collection.
61108Subdural drainageTwist-drill approach
61108 is for twist-drill evacuation or drainage of a subdural hematoma. 61107 is selected for implantation of a ventricular catheter for drainage.
61210Ventricular accessImplanted catheter, reservoir, or electrode
Both codes involve ventricular catheter implantation, but 61210 uses burr-hole access. Choose based on the documented cranial opening technique.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
