Billing tips
Verify that dosimetry calculations and treatment planning (CPT 77316-77318) are documented and billed separately, as these are not included in 77762
Impact: Prevents revenue loss of $150-400 per treatment course by capturing separately reimbursable planning services
Document the number of sources, channels, and dwell positions used to support intermediate complexity designation versus simple (77761) or complex (77763)
Impact: Proper complexity coding difference: 77761 ($463.89) vs 77762 ($545.04) vs 77763 ($626.19) - up to $162.30 difference
Bill per fraction/application, not per treatment course; each separate intracavitary insertion and removal constitutes a billable application
Impact: Typical cervical cancer protocol involves 3-5 fractions at $545.04 each = $1,635-2,725 total revenue if properly separated
Ensure imaging guidance codes (76965, 77002) are billed separately when ultrasound or fluoroscopy is used for applicator placement verification
Impact: Additional $50-150 per application for separately reimbursable imaging guidance when medically necessary and documented
For hospital billing, verify that both professional and technical components are captured, as identical facility/non-facility rates suggest global billing structure
Impact: Prevents 50% revenue loss from missing either component; full $545.04 payment requires complete service documentation
Coordinate billing with anesthesia services when conscious sedation or general anesthesia is used; do not report separate sedation codes 99151-99153
Prevents denials for bundled services; anesthesia professional bills separately while facility captures full technical component
