A new J code appears to be on the horizon.
The way you report units for adenosine may change next January.
CMS has posted a preliminary decision to discontinue current code J0152 (Injection, adenosine for diagnostic use, 30 mg [not to be used to report any adenosine phosphate compounds; instead use A9270]).
In its place, CMS proposes to introduce a new J code that will change the per-unit amount from 30 mg to 1 mg in the definition: Injection, adenosine for diagnostic use, 1 mg (not to be used to report any adenosine phosphate compounds; instead use A9270). If approved, the new code will be effective Jan. 1, 2014.
