Question:
Sentinel node mapping was performed and documented in both axillas. Is code +38900 reported once or twice?

Answer:
Sentinel node mapping may be reported bilaterally with a 50 modifier.  Claim form reporting in a single line format (38900-50) or on two lines (38900, and 38900-50) will be dependent on the payor.
