PR 51 Denial Code - Non-Covered Pre-Existing Condition
Code 51 indicates that the services billed are not covered because they are related to a pre-existing condition. On your remittance, this means the payer has determined that the patient's policy excludes coverage for these services due to this pre-existing condition clause.
Who Pays: Group Code Liability
With code 51, the group code is typically PR, meaning the patient is responsible for these charges. You may bill the patient for these non-covered services, as they fall outside the payer's obligations.
Why Claims Get Code 51
- The patient's insurance policy contains a pre-existing condition exclusion clause.
- The services provided are directly related to a condition that existed before the patient's insurance coverage began.
- The payer's records indicate a pre-existing condition that matches the services billed.
- The claim did not include documentation to prove the condition was not pre-existing.
- The patient's coverage start date overlaps with the treatment date of the condition.
How to Fix & Resubmit
- Verify the patient's policy details to confirm the pre-existing condition exclusion.
- Review the patient's medical history to ensure accurate information was provided to the payer.
- Check if there is documentation available that proves the condition is not pre-existing and resubmit with this proof.
- Contact the payer to verify if additional information can be submitted to reconsider the denial.
- If the condition is indeed pre-existing, bill the patient for the services as they are responsible.
Corrected Claim or Appeal?
For code 51, if documentation can prove the condition is not pre-existing, submit a corrected claim. If the condition is confirmed pre-existing, billing the patient is appropriate as an appeal won't alter coverage policy.
Preventing Future 51 Denials
- Ensure thorough documentation of the patient's medical history during registration.
- Verify insurance start dates to identify potential pre-existing conditions before service.
- Communicate with patients about their coverage limitations regarding pre-existing conditions.
- Maintain accurate records to quickly provide evidence if a condition is disputed as pre-existing.
