What 62223 covers

A neurosurgeon creates a new route for cerebrospinal fluid to leave a brain ventricle and reach the peritoneal cavity, pleural space, or another distal site. The operation commonly treats hydrocephalus and is performed in an operating room, with ventricular and distal catheters connected through the shunt system. The operative report should identify the ventricular origin, distal destination, and creation of a new diversion rather than adjustment or repair of an existing shunt.

Report 62223 for the new shunt when its distal destination fits this code; an atrial, jugular, or auricular destination points to 62220. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. In the same session, the highest-valued procedure is paid in full and other procedures receive the standard multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How the 62223 rate is calculated

Each of 62223’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

How to choose

62220CSF shunt
Choose 62220 for a ventricular shunt ending in the atrial, jugular, or auricular circulation; 62223 covers peritoneal, pleural, or other destinations.
62200CSF shunt
62200 covers ventricular catheter placement with a reservoir or drain. 62223 is for creation of a shunt carrying CSF to a distal body site.
62230Shunt revision
62230 describes revision or replacement of an existing shunt component; 62223 reports creation of a new ventricular shunt diversion.
62225Ventricular catheter
62225 concerns replacement or irrigation of a ventricular catheter, not construction of a new shunt to a distal site.

62223 billing questions

How does 62223 differ from 62220?

62223 is for a new ventricular shunt ending in the peritoneal cavity, pleural space, or another destination. Use 62220 when the distal endpoint is atrial, jugular, or auricular.

When would 62200 be more appropriate?

62200 describes ventricular catheter placement with a reservoir or drain, rather than creation of the distal shunt diversion reported with 62223. Base the choice on the procedure actually performed and documented.

Can the shunt components be reported separately?

The new ventricular-to-distal diversion is the service represented by 62223; do not separately report its integral catheter and shunt-system work as additional procedures.

Can modifier 50 be used for bilateral shunts?

No. CMS identifies bilateral adjustment as inappropriate for 62223, so modifier 50 is not appropriate.

How are an assistant or co-surgeon handled?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and the others are subject to the standard reduction.

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.
