|---|---|---|---|
| Highest education level achieved | |||
| High school (1 participant) | 18.66 minutes | —-a | 0.574 |
| Associate degree (2 participants) | 38.36 minutes | 0.652 | 0.486 |
| Bachelor's degree (2 participants) | 27.49 minutes | 0.728 | 0.436 |
| Master's degree (1 participant) | 17.82 minutes | —-a | 0.345 |
| ICD-9-CM coding experience | |||
| 10 years or less (1 participant) | 13.84 minutes | —-a | 0.496 |
| 11–15 years (1 participant) | 20.06 minutes | —-a | 0.573 |
| 16–20 years (3 participants) | 44.59 minutes | 0.652 | 0.405 |
| 21+ years (1 participant) | 27.78 minutes | —-a | 0.497 |
Note: Differences were averaged when a category had more than one coder.

With only one participant and no ICD-9-CM gold standard coder, the interrater reliability could not be calculated for these categories.
