B22 Denial Code - Diagnosis-Based Adjustment
Code B22 indicates that the payment adjustment is due to issues with the diagnosis code submitted on the claim. This means the payer has determined that the diagnosis does not support the service billed, leading to a reduction in payment.
Who Pays: Group Code Liability
For code B22, the group code will typically be CO, meaning the provider must write off the amount and cannot bill the patient. However, if the payer specifies PR, the patient may be responsible for the adjustment, but this depends on the payer's policy and contract terms.
Why Claims Get Code B22
- Incorrect diagnosis code submitted on the claim.
- Diagnosis code not matching the procedure code.
- Payer policy requiring a more specific diagnosis code.
- Diagnosis code submitted does not meet medical necessity requirements.
- Outdated diagnosis code used.
How to Fix & Resubmit
- Verify the diagnosis code used on the claim against the medical record documentation.
- Check for any payer-specific diagnosis requirements or policies that may apply.
- Correct the diagnosis code if an error is found and ensure it aligns with the procedure code.
- Re-submit the claim with the corrected diagnosis code if applicable.
- If the diagnosis is correct but denied, gather supporting documentation and prepare for a formal appeal.
Corrected Claim or Appeal?
Submit a corrected claim if the diagnosis code was incorrect. If the diagnosis was accurate but denied, a formal appeal with supporting documentation may be needed. If the adjustment is contractual, no action is required.
Preventing Future B22 Denials
- Ensure diagnosis codes are current and accurate at the time of claim submission.
- Cross-check diagnosis codes with procedure codes for compatibility before billing.
- Stay updated on payer-specific diagnosis requirements and policies.
- Implement thorough internal audits of claims before submission to catch potential errors.
