Billing tips
Bill catheterization code separately (36012-36015) as pulmonary artery catheterization is not included in 75746
Impact: Additional $75-150 reimbursement for catheterization component; critical for complete payment
Verify pre-authorization before procedure as most payers require prior approval for invasive pulmonary angiography
Impact: Prevents complete denial of $131 Medicare payment or higher commercial payments; reduces write-offs
Document medical necessity clearly including why non-invasive imaging (CT angiography) was inadequate or contraindicated
Impact: Reduces denial rate by 60-70%; invasive angiography requires strong justification in era of advanced CT imaging
Code separately for any interventions performed during same session using appropriate intervention codes with modifier 59
Impact: Captures additional reimbursement for therapeutic procedures; prevents bundling of separately payable services
Split bill between facility (TC) and professional (26) when applicable; ensure matching dates and technical details
Impact: Prevents processing delays and denials; ensures proper payment distribution between facility and physician
Report contrast materials separately using HCPCS codes for high-osmolar or low-osmolar contrast agents when allowed by payer
Impact: Varies by payer; some allow separate reimbursement for contrast materials adding $50-200 to total payment
