OA 105 Denial Code: Tax Withholding Adjustment
Code 105 means that a tax withholding was applied to the payment. This indicates that a portion of the payment was retained by the payer for tax purposes. You’ll see this adjustment on the remittance when tax regulations require withholding from provider payments.
Who Pays: Group Code Liability
With code 105, the withheld amount is typically adjusted using the OA (Other Adjustment) group code. This represents a reduction that is not billable to the patient, as it’s a regulatory withholding.
Why Claims Get Code 105
- The payer is required to withhold taxes from payments to the provider.
- The provider's tax identification information on file may trigger withholding.
- The claim was processed in a jurisdiction with specific tax withholding requirements.
- The payer has flagged the provider for tax withholding due to compliance issues.
- An incorrect tax identification number was used in the provider's profile.
How to Fix & Resubmit
- Verify the tax identification number and related information on file with the payer.
- Check if the withholding is in compliance with applicable tax regulations.
- Contact the payer to confirm the reason for the withholding if unclear.
- Ensure all tax-related documentation is current and submitted to the payer.
- If necessary, consult with a tax professional to address compliance issues.
Corrected Claim or Appeal?
For code 105, a formal appeal is generally not applicable as this is a regulatory withholding. Corrected claims are not appropriate; instead, ensure compliance with tax regulations to prevent future withholdings.
Preventing Future 105 Denials

- Review and understand the tax withholding regulations applicable to your practice location.
- Regularly verify that all required tax documentation is submitted to the payer.
