CO-286 Denial Code: Appeal time limit missed
The appeal arrived after the deadline — dismissed without merits review.
Why CO-286 happens
- ●Appeal deadline (often 60–180 days from denial) missed
- ●Denial worked from an aged AR report long after the clock started
How to fix a CO-286 denial
- 1
Request good-cause exception if circumstances justify (rare)
- 2
Otherwise write off and fix the intake-to-appeal pipeline speed
How to prevent it
Calendar appeal deadlines the day each denial posts — deadline first, work second.
