Physician-to-physician consultation has long been essential to care coordination, yet most clinical organizations fail to capture its full clinical and financial value. This whitepaper examines the evidence supporting structured interprofessional consultations, including improved patient outcomes, reduced specialist referrals, faster access to specialty expertise, and new reimbursement opportunities through CPT codes 99446–99452. It also explores how fragmented communication contributes to diagnostic delays, revenue leakage, and operational inefficiencies. Finally, the paper presents HCC Consult Core, ClinicianCore’s HIPAA-compliant consultation workflow that transforms informal curbside consults into documented, auditable, and billable clinical interactions while strengthening collaboration across specialties.
