The codes
| Code | Used for | Base units |
|---|---|---|
| 00830 | Hernia repairs in the lower abdomen, not otherwise specified | 4 |
| 00832 | Ventral and incisional hernias | 6 |
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.
Picking the right one
- Open inguinal and other lower abdominal hernias: usually 00830.
- Ventral and incisional hernias: 00832, which carries more base units.
- Laparoscopic repairs: these enter the abdominal cavity, so the intraperitoneal codes for the upper or lower abdomen often apply. Check your payer's crosswalk.
Read the operative note
Schedules often say "hernia repair" without saying which kind. The operative note tells you. Code from it.
