Populating MSP Insurance Type Code on Electronic Claims

When you identify beneficiaries that have Medicare as the secondary payer, you are required to submit electronic claims with the appropriate MSP insurance type code.

MSP Insurance Type Codes identify the reason for other coverage and shall be indicated on the ANSI 5010A1 within the 2000B and 2320 SBR05 loop/segment. When 2000B SBR01 equals “T” or “S,” the MSP insurance type code must equal one of the following values: 12, 13, 14, 15, 16, 41, 42, 43 or 47.

Beneficiaries insurance is classified in different MSP insurance type codes and categories such as:

  • Group Health Plan (GHP): types of coverage are based on current or past employment
  • Non-group Health Plan (NGHP): typically types of coverage that are a result of an accident or injury

The most common used MSP insurance type codes fall under GHP 12, 43 and 13.

NGS encourages J6 and JK providers and suppliers to use the CMS Model MSP Questionnaire available in CMS IOM Publication 100-05, Medicare Secondary Payer Manual, Chapter 3, Section 20.2.1 to screen for other payers that are primary to Medicare. Use of the CMS questionnaire will help you in determining the applicable MSP insurance type code.
