Documentation requirements
What must appear in the operative or office note to support the claim.
Source · Editorial brief grounded in 3 cited references ↓
- Named spinal level(s) treated (e.g., L4-L5) documented in the procedure note
- Diagnosis supporting stabilization device placement, such as lumbar stenosis or segmental instability
- Explicit statement that no neural decompression was performed at the treated level
- Device name, type, and implant lot/serial number recorded in the operative or procedure note
- Pre-procedure imaging (X-ray, MRI, or CT) confirming the pathology and level

What this code covers
Source · Editorial summary grounded in 3 cited references ↓
22870 covers placement of an interspinous or interlaminar stabilization device at the lumbar spine when no decompression (laminectomy, foraminotomy, discectomy) is performed at the same level during the same session. The procedure is most commonly performed by interventional pain management physicians and physiatrists — not orthopedic surgeons — which explains why anesthesiology and PM&R dominate the PUF utilization data.
The ZZZ global period means 22870 has no assigned global period of its own — it rolls into the global period of the primary procedure when billed alongside one. When billed as a standalone, pre- and post-operative services are not bundled. Payers scrutinize same-session billing closely: if any decompression was performed at the same spinal level, the correct code shifts to the companion code that includes decompression.
Documentation must establish the indication (typically symptomatic lumbar stenosis or instability), confirm the specific spinal level treated, and explicitly state that no decompression was performed. Operative or procedure notes that are vague about decompressive steps are the leading audit trigger for this code.
RVU & reimbursement
Component RVUs and Medicare national rate. Actual payment varies by GPCI locality.

Work RVU vs. total RVU
The work RVU (2.28) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (3.02) adds practice overhead and malpractice, and is what drives the Medicare payment below.
| Work RVU | 2.28 |
| Practice expense RVU | 0.53 |
| Malpractice RVU | 0.21 |
| Total RVU | 3.02 |
| Medicare national rate | $100.87 |
| Global period | days |
Payment by site of service
Medicare pays different rates by setting. HOPD typically pays substantially more than ASC for the same procedure.

Common denial reasons
The recurring reasons claims for CPT 22870 get rejected.
Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓
- Decompression performed at the same level same session — wrong code selected; the with-decompression companion code applies
- Lack of documentation explicitly ruling out decompression, triggering medical necessity denial or audit downcode
- Payer coverage policy excludes interspinous stabilization devices as investigational or not medically necessary without prior authorization
- Missing device implant documentation required by payer for implant-inclusive claims
- Insufficient conservative treatment history documented before interventional stabilization

Mira Scribe
Mira's AI scribe captures the spinal level treated, the device name and type, and a direct dictation statement confirming no decompression was performed at that level. That last element is the single most common audit flag for 22870 — its absence in the note is what drives payer downcodes to a decompression code or triggers medical necessity review.
