I know that the codes changed in 2020 for cpt 64420 and 64421. I know that you cannot code 64420 as a bilateral procedure. If the provider notes state " Gave a series of injections into the posterior cutaneous rami of the thoracic nerve distribution in the upper back bilaterally using 4 cc of buffered 5% dextrose and 1 % lidocaine". Billing 64420 and 64421 does seem appropriate since it states intercostal nerve, each additional level. It really isn't another level. How would we bill this? Thank you

Thank you for your question.
It is appropriate to use code 64420 RT and 64420 LT. Modifiers (LT and RT) will represent procedure was performed bilaterally.
we will use 64421 only when there is change in thoracic level. Hope it helps.
