Quick Explanation
Denial code CO 273 indicates that the billed behavioral health services did not meet the health plan's specific coverage or program guidelines. This typically occurs when a service fails to satisfy the payer's clinical criteria for medical necessity, credentialing requirements, or program-specific authorization protocols.
Common Causes for CO 273
Denials with code CO 273 typically happen for the following specific reasons:
- Failing to obtain prior authorization for specialized behavioral health services, such as Intensive Outpatient Programs (IOP) or Partial Hospitalization Programs (PHP).
- Billing for services rendered by a behavioral health provider whose specific licensure level or credentials are not recognized under the payer's program guidelines.
- Clinical documentation failing to demonstrate medical necessity according to standardized criteria, such as ASAM (American Society of Addiction Medicine) or LOCUS guidelines.
- Exceeding plan-specified limits on the frequency or duration of psychotherapy sessions without obtaining an approved clinical exception.
How to Prevent CO 273 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Perform comprehensive eligibility and benefits verification prior to treatment to identify specific behavioral health program guidelines and authorization requirements.
- Utilize standardized documentation templates that prompt clinicians to clearly record DSM-5 diagnoses, functional impairments, and measurable treatment goals.
- Ensure billing codes align with the provider's specific credentials and apply appropriate supervisory modifiers when services are performed by supervised clinicians.
- Establish an internal utilization review process to track session limits and proactively request authorization extensions before coverage thresholds are exceeded.

Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CO 273: "Behavioral Health denial code".
We are writing to appeal the denial of coverage under code CO 273 for the behavioral health services rendered. The enclosed clinical documentation clearly demonstrates that the treatment provided met all established medical necessity and program guidelines. The patient's clinical presentation, documented functional impairments, and ongoing treatment plan align fully with DSM-5 diagnostic standards and recognized clinical criteria, such as ASAM guidelines, justifying this level of care as clinically appropriate and necessary. Furthermore, all services were delivered by qualified, licensed professionals in compliance with CMS guidelines and state practice acts. We respectfully request that you review the attached clinical records and overturn this denial to allow payment for these essential services.
Attached please find:
1. A copy of the original claim.
