Billing tips

Document the exact number and type of views obtained (e.g., 'AP supine, AP upright, left lateral decubitus') in the radiology report
Impact: Prevents downcoding to 74019 (2 views, $34.96) - a difference of $6.44 per claim
Verify three or more distinct views were actually performed before billing 74021; if only 2 views obtained, bill 74019 instead
Impact: Avoids upcoding audits and ensures compliance; incorrect code selection is a common audit trigger
Bill professional and technical components separately when radiologist and facility are different entities
Impact: Ensures both parties receive appropriate payment; prevents coordination of benefits issues
Include specific clinical indication on order and report (e.g., 'rule out bowel obstruction' not just 'abdominal pain')
Impact: Reduces medical necessity denials by 30-40% and supports proper ICD-10 code assignment
Do not bill 74021 with 74022 (acute abdomen series) on same date unless distinct clinical indications exist and are documented
Impact: 74022 is comprehensive and includes 74021; bundling will result in denial of 74021 ($41.40 lost)
For inpatient hospital settings, ensure correct revenue code (0320 for diagnostic radiology) accompanies CPT 74021
Impact: Prevents claim rejection and delays in payment processing
