What 176 means
The payer will not pay because the order or prescription had expired or was too old for the date of service.
Orders often have a limited life. This code means the order on file was not valid for the date the service was given, for example because it had lapsed or needed renewal.
Ongoing supplies and repeat services are where this shows up most. Check the order's dates against the payer's renewal rules.
Group codes seen with 176
On a remittance, 176 comes after a group code. These are the ones it is most often reported with:
- CO 176 (Contractual Obligation): The provider's side of the ledger. The reduction comes from the payer contract or a rule the provider has to follow, and the patient normally cannot be billed for it.
The payer chooses the group code for each adjustment, so the same reason code can appear with another group code on your remittance. Read the two together. More about group codes.
Common causes
- The order was older than the payer allows for this service or item.
- A renewal or new order was needed and not obtained.
- The length of need on the original order had ended.
What to do next
- Check the order date and length of need against the date of service.
- Get a renewed order from the prescriber.
- Resubmit or appeal with the current order if it was in place on the date of service.
