PR 45 means the healthcare provider charged more than the allowed amount. Think of it like this:

- But sometimes the doctor has to write off this amount
PR 119 in Medical Billing Explained
PR 119 appears when you’ve reached your benefit maximum for a specific time period. This could be:
- Monthly physical therapy visit limits
- Yearly vision care maximums
- Quarterly mental health session limits
