Carol Lewis

Description

2420E N3/N4 - the Imp Guide note states, required when a Durable Medical Equipment Regional Carrier Certificate of Medical Necessity (Medicare DMERC CMN) is used on service line for Medicare claims.

Based on the Imp Guide note, is it correct to say that 2420E N3/N4 segments are required when 2400 PWK (DMERC CMN Indicator) is present?

If not, please provide a clear usage for the 2420E N3/N4 and 2400 PWK segments.
