Denial Code CO-150: Not Deemed Medical Necessity - Payer
What Does Code 150 Mean?
Payer deems the information submitted does not support this level of service, this many services, this length of service, this dosage, or this day's supply.
Group Code CO (Contractual Obligation): The provider has agreed to accept the payer's determination. The patient is generally not responsible for this amount.
Why Does This Happen?
Payer's utilization review found that clinical criteria were not met for the requested level or volume of service.
How to Resolve It
- 1Request the specific clinical criteria used for the denial
- 2Schedule a peer-to-peer review
- 3Gather supporting documentation including recent labs, imaging, and specialist notes
- 4Submit appeal with evidence-based guidelines
