UB04 Patient's Relation to Insured Code G8: Other Relationship

Overview

Code G8 in UB-04 Form Locator 59 (Patient's Relation to Insured) represents "Other Relationship." This code is used when the patient's relationship to the insured party does not fit any of the standard defined categories such as spouse, self, child, employee, or life partner. [1] The code is part of the standard UB-04 code set for patient relationship to insured, which includes codes 01 (Spouse), 18 (Self), 19 (Child), 20 (Employee), 21 (Unknown), 39 (Organ Donor), 40 (Cadaver Donor), 53 (Life Partner), and G8 (Other Relationship). [2] This code serves as a catch-all for unusual or non-standard relationships that do not fall under the predefined categories.

When to Use

Code G8 should be used when the patient's relationship to the insured person does not match any of the other defined relationship codes. [1] This code is appropriate when the patient is covered under another person's insurance policy but the relationship is not specifically defined by the standard code set. [2]
