CO-152 Denial Code: Length of service not supported
The payer downcoded or denied because documentation doesn't support the billed length of service — the duration cousin of CO-150.
Why CO-152 happens
- ●Time-based codes billed without documented start/stop times
- ●Visit length inconsistent with the payer's norms for the service
How to fix a CO-152 denial
- 1
Appeal with time documentation if the record supports the duration
- 2
Accept the recode and educate providers on time documentation if it doesn't
How to prevent it
Require start/stop times (or total time statements) on every time-based service.
