Billing tips

Always bill 78808 separately from the imaging code - this is an unbundled service that stands alone
Impact: Captures full $38.82 that is often missed when billers assume injection is included in imaging code
Link appropriate diagnosis code to justify the nuclear medicine study, not just 'injection' as the reason
Impact: Reduces denial rate by 30-40% when medical necessity clearly supports the diagnostic study
Document exact time of injection and dose administered in medical record; required for radioactive material tracking
Impact: Essential for compliance; missing documentation can trigger denials or regulatory issues
Bill on same date of service as the imaging study; split billing across dates raises red flags
Impact: Prevents coordination of benefits issues and potential audits for unbundling
Verify that your facility's radioactive materials license covers the specific radiopharmaceutical being administered
Impact: Prevents claim denials and potential regulatory violations; license scope varies by state
For multiple injections on same day, use modifier 59 only when truly distinct procedures; document separate medical necessity
Impact: Appropriate use can generate additional $38.82 per injection; inappropriate use triggers audits

What are common denial reasons for CPT 78808?

Common denials include: incorrect bundling with imaging codes, lack of medical necessity documentation, duplicate billing without appropriate modifiers, and missing documentation of the radiopharmaceutical dose and administration time required for radioactive material tracking.
