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. 1

    Request good-cause exception if circumstances justify (rare)

  2. 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.
