This comprehensive guide provides step-by-step instructions for healthcare entities on how to accurately complete specific fields on the modified Form CMS-1500 for **CMS-1500 roster billing guidelines**, especially for immunization and **vaccine claim submission**. Understanding these procedures is crucial for efficient **immunization billing instructions** and successful reimbursement from **Medicare A/B MAC roster** programs.
Understanding Roster Billing for Mass Immunizations
Roster billing is a streamlined method used by healthcare providers, particularly for mass immunization programs, to submit multiple claims for vaccine administration to Medicare. Instead of submitting individual CMS-1500 forms for each patient, providers can use a single modified CMS-1500 form as a cover document for an attached roster listing all patients who received the service. This approach significantly reduces administrative burden, improves efficiency for large-scale vaccination efforts (e.g., flu clinics), and ensures timely processing of **vaccine claim submission**.
Entities submitting roster claims to A/B MACs (B) must complete the following blocks on a single modified Form CMS-1500, which serves as the cover document for the roster for each facility where services are furnished. In order for A/B MACs (B) to reimburse by correct payment locality, a separate Form CMS-1500 must be used for each different facility or physical location where services are furnished.
Key Sections of the Modified CMS-1500 for Roster Billing
Item # Instruction
Item 1: (Type of Health Insurance Coverage): Mark an ‘X’ in the ‘Medicare’ block. This indicates the primary payer for the services listed on the attached roster.
Item 2: (Patient’s Name): Enter “SEE ATTACHED ROSTER”. This instruction is critical because the individual patient names, identifying information, and Medicare numbers are detailed on the separate roster document that accompanies this cover CMS-1500 form.
Item 11: (Insured’s Policy Group or FECA Number): Enter “NONE”. This field is typically for supplemental insurance information. For Medicare roster billing, this specific field is not used in the cover document.
Item 20: (Outside Lab?): Mark an “X” in the ‘NO’ block. This confirms that the services (immunizations) were not performed by an outside laboratory.
Item 21: (Diagnosis or Nature of Illness or Injury): Line A: Enter the appropriate ICD-10-CM diagnosis code. For immunizations, this typically indicates the reason for the vaccination (e.g., Z23 for ‘Encounter for immunization’). CRITICAL UPDATE: Only ICD-10-CM codes are applicable for Medicare claims; ICD-9-CM is no longer used. In the ‘ICD Ind.’ block, enter ‘0’ (zero) to indicate that an ICD-10-CM code is being used. This indicator must be a single digit placed between the vertical dotted lines.
Item 24B: (Place of Service (POS)): For Line 1 and Line 2 (and subsequent lines if applicable for multiple services), enter “60”. Rationale: POS Code ’60’ specifically denotes ‘Mass Immunization Center’ and is mandatory for all **CMS-1500 roster billing guidelines** submissions to Medicare. Using any other POS code will likely result in a claim denial.
Item 24D: (Procedures, Services, or Supplies):
Line 1: For the Pneumococcal vaccine, enter “90732”. For the Influenza Virus vaccine, enter the appropriate, current influenza virus vaccine code.
Line 2: For Pneumococcal vaccine Administration, enter “G0009”. For Influenza Virus Vaccine Administration, enter “G0008”.
Verification of Vaccine Codes: While 90732, G0009, and G0008 are widely recognized for Medicare roster billing for pneumococcal and influenza vaccines, it is essential to always verify the most current codes. Healthcare Common Procedure Coding System (HCPCS) codes are updated periodically. Providers should routinely consult the official CMS HCPCS updates for the latest validity and appropriate usage.
Item 24E: (Diagnosis Pointer): For Lines 1 and 2 (and any subsequent service lines), enter “A”. This indicates that the diagnosis code entered in Item 21, Line A, is applicable to the services listed on these lines.
Item 24F: ($ Charges): The billing entity must accurately enter the charge for each listed service. If the entity is providing the vaccine or its administration at no charge (e.g., due to a public health program), enter “0.00” or “NC” (no charge) on the appropriate line for that item. Important Note for System Compatibility: If your billing system cannot accept a line item charge of “0.00” for an immunization service, do not submit that line item. Similarly, electronic media claim (EMC) billers should only submit line items for free immunization services on EMC pneumococcal or influenza virus vaccine claims if their system supports such entries. This prevents potential claim rejection due to incompatible charge entries.
Item 27: (Accept Assignment): Mark an “X” in the ‘YES’ block. This indicates that the provider agrees to accept the Medicare-approved amount as full payment for the services, and will not bill the patient for any additional charges beyond deductibles or coinsurance.
Item 29: (Amount Paid): Enter “$0.00”. This field is used to report any amounts the patient has already paid. For services submitted via roster billing, this amount is typically zero on the cover document.
Item 31: (Signature of Physician or Supplier): The authorized representative of the billing entity must physically sign and date the modified Form CMS-1500. This signature certifies the accuracy of the information provided and affirms the provider’s agreement to the terms of Medicare participation.
Item 32: (Service Facility Location Information): Enter the complete name, address, and ZIP code of the physical location where the immunization services were provided. This information is crucial for correct payment locality and applies even to centralized billing operations.
Item 32a: (Service Facility NPI): Enter the National Provider Identifier (NPI) of the specific service facility where the services were rendered. The NPI identifies the location uniquely.
Item 33: (Billing Provider Info & P.O. Box): The billing entity must complete this item with its full name, address, and telephone number. Also, include the Provider Identification Number (PIN, if applicable, distinct from the Unique Physician Identification Number) or the NPI when required by your Medicare A/B MAC.
Item 33a: (Billing Provider NPI): Enter the National Provider Identifier (NPI) of the billing provider or group. Current Requirement: This NPI requirement has been in effect since May 23, 2007, and remains mandatory for all Medicare claims, including those submitted via **Medicare A/B MAC roster** billing.

Common Errors in CMS-1500 Roster Billing and How to Avoid Them
- Incorrect Place of Service (POS) Code: Failure to use POS Code ’60’ for mass immunizations is a common reason for claim denials. Always ensure ’60’ is entered in Item 24B.
- Outdated or Incorrect Diagnosis/Procedure Codes: Using ICD-9-CM instead of ICD-10-CM, or using expired CPT/HCPCS codes for vaccines and administration, will lead to rejections. Regularly check CMS HCPCS updates for current codes.
- Missing or Invalid NPIs: Ensure both the service facility NPI (Item 32a) and the billing provider NPI (Item 33a) are correctly entered and valid.
- Improper Handling of ‘No Charge’ Services: If a service is provided at no charge, ensure your billing system can properly submit ‘0.00’ or ‘NC’ in Item 24F, or omit the line item if your system cannot. Incorrect entries can cause processing issues.
- Incomplete or Unsigned Cover Document: The modified CMS-1500 must be fully completed and signed by an authorized representative in Item 31 to be considered valid as a cover document for the roster.
- Mismatch Between Cover and Roster: Discrepancies between information on the modified CMS-1500 cover document and the attached patient roster can lead to delays or denials. Ensure consistency.
Frequently Asked Questions (FAQ) about CMS-1500 Roster Billing
