Billing tips

Document comprehensive examination of the nerve across multiple anatomic levels in both transverse and longitudinal planes to meet the 'comprehensive' requirement
Impact: Failure to document comprehensive evaluation can result in downcoding or complete denial, losing the full $70.19 reimbursement
Bill bilateral examinations as two units (one for each extremity) with RT/LT modifiers or modifier 50, not as a single service
Impact: Proper bilateral billing yields $140.38 instead of $70.19 for single-sided examination
Store permanent images showing both longitudinal and transverse views of the nerve with measurements of cross-sectional area at key anatomic landmarks
Impact: Missing stored images is a top audit trigger and can result in 100% recoupment during post-payment review
Ensure the written report specifies which nerve(s) were examined, anatomic levels scanned, measurements obtained, and clinical correlation
Impact: Incomplete reports lead to medical necessity denials and potential $70.19 recoupment per claim
Do not bill 76883 with limited ultrasound codes (76882) for the same extremity on the same date without modifier 59 and distinct documentation
Impact: Bundling edits will deny the second service; proper modifier use can preserve additional reimbursement
Verify LCD/LMA coverage for peripheral nerve ultrasound as some MACs require specific ICD-10 codes or prior authorization
Impact: Non-covered diagnosis codes result in automatic denial; checking coverage before service prevents $70.19 write-off
