Is anyone having trouble getting paid for intercostal nerve blocks? I bill for an ASC and the physician did intercostal nerve block at 4 levels, I billed 64420 and 64421 with 3 units. The insurance, UHC Medicare, denied pmt on 64420. I looked up the NCCI edit and it states that 64420 is a column 2 code for 64421. My question is what modifier to use. I know 59 would not be appropriate because it's not a distinct procedure and the CPT code book states to use 64421 in conjunction with 64420 what multiple nerves are injected.
