Common codes
| Code | Used for | Base units |
|---|---|---|
| 00600 | Cervical spine and cord procedures | 10 |
| 00620 | Thoracic spine and cord procedures | 10 |
| 00630 | Lumbar spine procedures | 8 |
| 00670 | Extensive spine and cord procedures, such as multi-level instrumentation | 13 |
Base units shown are the standard values most payers use. Check your payer and the current year's CMS base unit file before relying on them.
When to use 00670
Extensive procedures, like multi-level fusions with instrumentation, may qualify for 00670 and its higher base units. The operative note has to support it. Don't use it just because a case was long.
Other things to bill
- Arterial lines and central lines, when placed. See line billing.
- Physical status for payers that pay it
Long cases
Spine cases can run many hours. Make sure handoffs between providers are recorded with times, so the claim reflects the right staffing modifier for the whole case.
