Summary
Health Net now requires all Medicare revenue codes to be submitted in four-digit format with leading zeros to avoid claim rejections. Claims using three-digit formats (e.g., '022' instead of '0022') will be rejected.
Action Required
Immediately: Billing team must update billing system to ensure all Medicare revenue codes are formatted as four digits with leading zeros (e.g., use '0022' not '022'). Review all claim templates and forms to verify four-digit revenue code format. Test claims before submission to avoid rejections.
