Billing tips
Split bill when appropriate: Use modifier 26 for professional component in hospital settings where facility owns equipment, and ensure facility bills TC component
Impact: Prevents $25.23 loss from unbilled professional services; proper split billing ensures full reimbursement for both components
Document medical necessity explicitly in ordering notes and interpretation reports, especially for repeat studies within 30 days
Impact: Reduces denial rate by 60-80% on Medicare claims; prevents medical necessity denials averaging 15-20% of 71045 claims
Verify that 71045 was not already performed same day at another facility before ordering; query patient and check referral documentation
Impact: Prevents duplicate service denials which require time-consuming appeals and delay payment by 45-60 days
Use 71046 (2 views) or 71047 (3 views) instead of 71045 when multiple views are obtained; do not bill multiple units of 71045
Impact: 71046 reimburses at $30.91 vs. $25.23 for 71045; billing multiple 71045 units will be downcoded, losing $5+ per study
Ensure interpretation report is signed and dated same day as or within 24-48 hours of image acquisition for timely filing
Impact: Delays beyond 7-10 days increase denial risk; maintains compliance with Medicare timely filing requirements
Link appropriate ICD-10 diagnosis codes that support medical necessity; avoid screening codes (Z codes) unless payer-specific coverage exists
Impact: Screening indications without coverage deny at 90%+ rate; proper diagnostic coding reduces denials by $200-500 monthly for typical practices
Common denials
Medical necessity not established - routine screening without covered indication
How to appeal: Submit clinical documentation showing signs/symptoms warranting imaging (cough, fever, chest pain, SOB); cite specific payer LCD/NCD coverage criteria; provide relevant patient history and physical exam findings supporting diagnostic (not screening) intent
Duplicate service - same or similar procedure already performed same day or recent timeframe
How to appeal: Provide documentation showing clinical change requiring repeat imaging; submit medical records demonstrating different clinical indication or inadequate initial study; use modifier 76/77 on corrected claim with supporting documentation
Bundled/inclusive with E/M service or other procedure same day
How to appeal: Verify actual bundling rules via NCCI edits; if separate service, document distinct nature and medical necessity; most 71045 services are separately billable from E/M when medically indicated
Missing or incomplete interpretation report in medical record
How to appeal: Submit complete signed and dated radiologist interpretation report; ensure report includes all required elements (technique, findings, impression); demonstrate report was completed within acceptable timeframe of image acquisition
Frequently asked questions
What is the Medicare reimbursement rate for CPT 71045 in 2025?
The 2025 Medicare national average reimbursement rate for CPT 71045 is $25.23 for both facility and non-facility settings. This rate is based on 0.78 total RVUs multiplied by the 2025 conversion factor of 32.3465. Actual reimbursement may vary by geographic locality.
What is the difference between CPT 71045 and 71046?
CPT 71045 is a single-view chest x-ray (one image angle), while CPT 71046 is a two-view chest x-ray (typically PA and lateral views). The two-view exam (71046) provides more comprehensive evaluation and reimburses at $30.91 compared to $25.23 for the single view. You cannot bill both codes together for the same encounter.
Do I need modifier 26 when billing CPT 71045?
Use modifier 26 only when billing the professional component (physician interpretation) separately from the technical component. This applies in hospital or facility settings where you did not provide the equipment or technical staff. In office settings where you provide both components, bill 71045 without a modifier for the global service.
Can CPT 71045 be billed with an office visit on the same day?
Yes, CPT 71045 can be billed separately with an E/M visit on the same day when medically necessary. There are no NCCI edits bundling 71045 into E/M services. Ensure documentation supports the medical necessity for the x-ray based on the clinical evaluation during the visit.
How many RVUs is CPT code 71045 worth?
CPT 71045 has 0.78 total RVUs for 2025, consisting of 0.18 work RVUs, 0.58 practice expense RVUs (both facility and non-facility), and 0.02 malpractice RVUs. This is relatively low compared to other imaging procedures, reflecting the simple nature of a single-view examination.
What diagnosis codes are typically used with CPT 71045?
Common ICD-10 codes include R05.9 (cough), R06.02 (shortness of breath), R07.9 (chest pain), J18.9 (pneumonia), Z01.812 (pre-operative examination), I50.9 (heart failure), and J44.9 (COPD). Always use the most specific diagnosis code that accurately reflects the clinical reason for ordering the x-ray to establish medical necessity.
Can I bill multiple units of CPT 71045 if we take multiple single views?
No, you should not bill multiple units of 71045. If multiple views are obtained, use the appropriate multi-view code: 71046 for two views, 71047 for three views, or 71048 for four or more views. Billing multiple units of 71045 will result in downcoding to a single unit or denial for incorrect coding.
