The code
| Code | Used for | Base units |
|---|---|---|
| 01214 | Total hip arthroplasty | 8 |
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.
What to check on every hip
- Time. Long cases mean more time units, and gaps in the record cost more. Make sure there's a clear start and stop.
- Physical status. Many hip patients are older with other conditions. P3 is common. Bill it to payers that pay for it.
- Age. Commercial plans that pay qualifying circumstances may pay extra for patients over 70 (99100).
- Blocks. A fascia iliaca or other block for pain after surgery may be separately billable if the surgeon asked for it and it wasn't the main anesthetic. See nerve block billing.
- Lines. If you placed an arterial line, it can usually be billed separately. See line billing.
Revisions
Revision hip surgery has its own anesthesia codes and higher base units. Make sure the surgeon's operative note supports the revision before you code it.
