CPT Code 22633 | Description, Procedure & Billing Guidelines (2022)

Report CPT 22633 for the procedure in which a provider permanently joined two adjoining vertebral bodies in the patient’s lumbar area.

1. What Is CPT Code 22633?

CPT 22633 covers a procedure in which a provider permanently joins two adjoining lumbar vertebral bodies to prevent further damage or pain to the patient’s joint.

This procedure can be performed with different approaches.

2. Description

The CPT book describes CPT code 22633 as follows: “Arthrodesis, combined posterior or posterolateral technique with posterior interbody technique including laminectomy and/or discectomy sufficient to prepare interspace (other than for decompression), single interspace, lumbar.”

3. Procedure

The 22633 CPT code procedure begins with the provider placing the patient in the prone position after they have been prepped and anesthetized.

Then, they make an incision over the patient’s lower spine (lumbar vertebral area), or they choose posterolateral fusion by exposing the transverse process and facet joints with incisions on the sides of the patient’s spine.

Next, the surgeon gets access to the vertebrae with retractors and uses powered tools to remove diseased cartilage and tissue. They also excise cortical bone fragments and the articular cartilage.

Then, the provider facilities fusion with discectomy, laminectomy, or both. They then fill the gap created with discectomy and/or laminectomy with bone graft material cut from the fossa, laminae, or graft material from a donor or other body part.

They continue the procedure by making the fusion durable using different internal fixation devices, such as nails, plates, or screws.

Finally, they place a drain (if necessary), irrigate the surgical wound with saline and antibiotics, close it in layers, and check for bleeding before ending the procedure.

4. How To Use CPT 22633

CPT code 22633 can only be used for a single lumbar interspace. Use add-on CPT code 22634 for every additional interspace.

Check the payer’s guidelines because bone graft material might be reported separately. The same goes for discectomy or laminectomy.

You can not report CPT 22612 or CPT 22630 for the same interspace.
