This table may be extended by local agreement during implementation to cover site-specific master files (z-master files). HL7 recommends use of the HL7 assigned table number as the master file identifier code if one is not specified in Table 0175. For example, a master file of Marital Status codes would be identified by HL70002 as the MFI-1 - Master file identifier. Refer to HL7 table 0175 - Master file identifier code for valid values.",
