IN2 — Insurance Additional Information
Optionally follows IN1 in ADT and DFT messages. One IN2 per IN1.
The IN2 segment contains supplemental insurance information that does not fit in IN1, including military information, Medicaid details, and additional employment and subscriber data.
Real-World Context
IN2 carries the overflow from IN1, mostly for military, Medicaid, and CHAMPUS eligibility. The fields that matter most in practice are Medicaid case number (IN2.8), Medicare health insurance card number (IN2.6), and employment details (IN2.3 through IN2.5). Billing teams often find IN2 more reliable than IN1 for military benefit data.
