Rejection/Denial Codes
D1 - Rejected - Medical Records Required
The patient’s medical records are requested in order to review the claims for payment. Often this remark is used when considering the emergency room treatment or to determine discrepancies between procedure and diagnosis codes or levels of treatment provided.

D3 - Rejected - Age Discrepancy with Procedure Code Billed; Refile
The procedure code submitted is not appropriate based on the age of the member.
D4 - Rejected - Invalid Modifier, $0 Payment Modifier OR Invalid Modifier/Procedure Code Combination; Refile
Submit appropriate CPT-4 modifiers with CPT codes and HCPCS modifiers with HCPCS codes. Invalid modifier and procedure code combinations are not covered. Providers should submit appropriate modifiers even if they do not affect payment of the claim. The inappropriate use of modifiers may generate audits or denials.
D5 - Rejected - Invalid Procedure Code; Refile within the Follow Up Time Period
Valid procedure codes for Gateway are those codes which are listed on the fee schedule for the most current update or approved by Gateway. The codes include currently active CPT-4 codes, or HCPCS codes. Inappropriate use of codes may generate audits or denials.

D8 - Rejected - Expenses Incurred After Coverage Terminated (Please see D63 for denial if expenses incurred prior to enrollment)

Eligibility can be verified with Gateway Health Plan® 24 hours a day, 7 days a week. Refer to the Eligibility section of the Policy and Procedure manual for more details.
D9 - Denied - Benefits Terminated for Date of Service
Benefits for the services billed were not allowed due to a medical necessity or a level of care discrepancy.

D10 - Rejected - Exceeds Maximum Filing Time Limit
365 days from the date of service is allowed for initial claim submissions. All claims are inventory controlled and date-stamped the day they are received in the Gateway claims processing office. A claim will only be accepted as filed if it is received within 365 days from the date of service.
D11 - Rejected - Resubmit with EOB from Primary Carrier to Include Reason for Denial
Based on existing other insurance information, the member who received the services provided has other primary insurance.

D12 - Denied - Motor Vehicle Accident - Auto Insurer is Primary/EOB
The claim is related to a motor vehicle accident for which another carrier or party may be liable.

D21 - (NOT APPLICABLE TO MEDICARE – DO NOT USE)
D22 - Rejected - No Valid Precert on File (Wording change 7/20/09)
D22 will be used for denying precerts that are missing, invalid or expired. Certain services require precertification (authorization) from Gateway Health Plan® Utilization Management Department. A provider must call the UM Department at Gateway on the day of or before a service takes place to receive a review of medical appropriateness for the service. If a precertification is issued, it is time and procedure specific and will expire. Please confirm the precertification with the UM Department. Retrospective precertification will not be given.
D23 - Denied - Same Service Paid to a Different Provider OR Billing Provider Ineligible to Submit Charges
Another provider billed for the same procedure or service under the same circumstances on the same day and was reimbursed.

Also, bills received from providers who are not eligible for reimbursement will be denied.
D24 - (NOT APPLICABLE TO MEDICARE – DO NOT USE)
D25 - Denied - Duplicate Claim - Paid/Denied Previously
This claim was previously processed and a payment or denial was issued.

All appeals/grievances should be directed to the Appeals Department. Refer to the Appeals and Grievance section of the Policy and Procedure manual for more details.
D26 - Duplicate Claim - Original Claim Under Review
This service or claim has been acknowledged as received by Gateway Health Plan®; however, either a duplicate submission during the same payment period or technical system constraint, such as a fee or code in development or waiting to be added to the system has caused processing to be delayed.

D33 - Rejected - Charges OR Units Not Submitted on Bill
The provider did not submit a charge for a billed procedure code or units required on a UB-04; therefore, Gateway is unable to issue any payment since the provider did not indicate charges OR number of units being billed on a UB-04.
D34 - Itemize Payments by Procedure Code on the EOB
If Gateway Health Plan® is secondary to a member’s primary medical insurance, Gateway is required to consider payment to the provider of service. When the EOB is sent to Gateway, each procedure code processed must be associated with some portion of the charges on the EOB or the claims system cannot determine a correct payment. Therefore, further detail is requested from the primary insurer.
D35 - DO NOT USE CODE AS OF 7/20/09 - Rejected – Submitted Bill Does Not Match Authorization
D36 - Rejected - Discrepancy in Level of Care with Authorization
When the Utilization Management Department issues an Authorization for a service or procedure, the level of care provided must be defined. For example, an inpatient stay will have a bed defined (i.e., a pediatric bed in a semi-private room). If the bill submitted by the provider indicates a discrepancy in the care rendered versus what was actually precertified, then the claim is denied for this reason.
D37 - Rejected - Must Use Contracted and/or Authorized Procedure Code(s) for Ambulance/Transport Services
All ambulance/transport providers are required to bill Gateway with procedure codes that are contracted and/or authorized for reimbursement.
