X-ray exam ribs uni 2 views
CPT code 71100 covers a basic x-ray examination of the ribs on one side of the body using two different viewing angles. This diagnostic imaging helps doctors identify rib fractures, abnormalities, or other chest wall injuries.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Always append appropriate laterality modifier (LT or RT) to specify which side was imaged
Impact: Prevents automatic denials and information requests that delay payment by 14-30 days on average
Verify that only two views were obtained; if three or more views were taken, use CPT 71111 instead to capture full reimbursement
Impact: CPT 71111 reimburses at a higher rate; undercoding with 71100 when 71111 is appropriate results in lost revenue per exam
Document medical necessity clearly in the order and interpretation, especially for non-trauma cases
Impact: Reduces denial rate by approximately 25-40% for medical necessity reviews, particularly with Medicare Advantage and commercial payers
Do not bill 71100 bilaterally; if both sides are imaged, bill 71101 instead as the appropriate bilateral code
Impact: Billing 71100 with both LT and RT modifiers will result in denial; proper use of 71101 ensures correct $52-56 reimbursement for bilateral imaging
Separate professional and technical components when different entities provide interpretation versus imaging services
Impact: Ensures accurate revenue distribution; facility bills TC modifier, radiologist bills 26 modifier, preventing duplicate billing and compliance issues
Check for chest x-ray (71046, 71047, 71048) performed on same date; payers may deny 71100 as inclusive if clinical indication overlaps
Impact: Prevents denials on 15-20% of claims when both chest and rib series ordered; requires distinct diagnostic indications in documentation
