CO-174 Denial Code: Not prescribed prior to delivery
The prescription/order is dated after the item was delivered — the sequence violates coverage rules.
Why CO-174 happens
- ●Equipment delivered before the written order (common in DME urgency situations)
How to fix a CO-174 denial
- 1
If a valid verbal order preceded delivery, submit documentation per payer policy
- 2
Otherwise the claim typically isn't payable — fix the dispensing sequence
How to prevent it
Enforce written-order-prior-to-delivery (WOPD) checks for items that require it.
