Medicare Part B Electronic Claims that Exceed the Threshold for Charges and Units of Service 

Medicare Part B electronic claims (ANSI X12 837P) with total charges exceeding $99,999.99 cannot be processed in the MCS. If a single claim exceeds the threshold charge amount, it will reject/deny.

Units of service cannot exceed 9,999 per line item. If a single claim exceeds the maximum unit threshold, it will reject/deny.

Maximum Charges Allowed $99,999.99

When total charges exceed $99,999.99 for a single date of service follow the guidance below to ensure claims are submitted accurately and do not reject/deny:

  • Split the claim – depending on charges this may be two or more claims
    • For the same service, procedure, or drug add modifier 76 to the subsequent claim(s)
      • Effective on and after 11/6/2023, drug and biological claims missing the required information will be rejected
    • For a different service or procedure add modifier 59 to the subsequent claim(s) 
  • Submit all claims for that single date of service at the same time
  • Include a comment on each claim, identifying this is a series of claims due to the total charges exceeding the $99,999.99 threshold
    • On the 837P electronic submission, enter comments into Loop 2300 or 2400, Segment NTE02
    • Sample comments:
      • Claim 1 of 2 total charges equal $150,000
      • Claim 2 of 2 total charges equal $150,000

Maximum Units Allowed 9,999

When the total units exceed 9,999 for a single line item follow the guidance below to ensure claims are submitted accurately and do not reject/deny:

  • Split the claim into sperate line items and/or sperate claims as applicable 
  • Be mindful to not exceed MUE values
    • For the same service, procedure, or drug add modifier 76 to the subsequent claim(s)
      • Effective on and after 11/6/2023, drug and biological claims missing the required information will be rejected
    • For a different service or procedure add modifier 59 to the subsequent claim(s) 
  • When it is necessary to submit multiple claims
    • Submit all claims for that single date of service at the same time
    • Include a comment on each claim, identifying this is a series of claims due to the total units exceeding the threshold
      • On the 837P electronic submission, enter comments into Loop 2300 or 2400, Segment NTE02
      • Sample comments:
        • Claim 1 of 2 units exceeding the maximum threshold
        • Claim 2 of 2 units exceeding the maximum threshold
