CARC 152 Denial Code - Fix Length of Service Issues
Code 152 indicates that the payer has determined the submitted documentation does not justify the length of service billed. This means the payer believes the service duration is either too long or not adequately explained based on the information provided. They may refer you to additional policy details found in the 835 Healthcare Policy Identification Segment, if included.
Who Pays: Group Code Liability
When code 152 is applied with group code CO, the provider must write off the amount and cannot bill the patient. If applied with PR, the patient may be responsible for the denied amount, but this is rare for service length denials.
Why Claims Get Code 152
- Insufficient documentation supporting the billed length of stay or service duration.
- Missing clinical notes that justify extended service time.
- Failure to submit required prior authorization for extended services.
- Errors in documenting the start and end times of services.
- Mismatched service dates between claim and medical records.
How to Fix & Resubmit
- Review the payer's specific policy regarding length of service documentation to understand their requirements.
- Check the 835 Healthcare Policy Identification Segment for any additional information the payer provided regarding the denial.
- Gather and review the clinical documentation to ensure it supports the length of service billed.
- If documentation is incomplete or incorrect, obtain the necessary records or corrections from the provider.
- Resubmit the claim with complete and accurate documentation, or file an appeal if the documentation was correct but misinterpreted by the payer.
Corrected Claim or Appeal?
Submit a corrected claim if documentation was initially incomplete or incorrect. An appeal is warranted if the documentation was complete and accurate but not recognized by the payer. If the denial is correct per contract, adjustments may be final.
Preventing Future 152 Denials
- Ensure all claims include complete clinical documentation justifying the billed service duration.
- Train staff to verify prior authorizations cover the entire length of service before billing.
- Implement a checklist for verifying documentation against payer requirements before submission.
- Regularly audit claims for common documentation errors that lead to denials like code 152.
