Indiana Health Coverage Programs (IHCP) has added new COVID-19 testing codes and updated reimbursement rates for COVID-19 related services. The policy provides specific billing guidance for COVID-19 testing, specimen collection, and diagnosis coding, with coverage extended to all IHCP members including limited-benefit programs.
Action Required
Immediately: Billing team must update system to include new COVID-19 codes (87635, G2023, G2024, U0001, U0002) with specified reimbursement rates and revenue code linkages. Update encounter forms to include new diagnosis codes (Z03.818, Z11.59, Z20.828, U07.1). Resubmit any previously denied claims due to invalid revenue code linkages. Ensure proper diagnosis coding based on date of service - use U07.1 for confirmed positive cases after April 1, 2020.
