Question: North Carolina Subscriber Answer: Second, check whether your physician is injecting dexamethasone acetate (J1094, Injection, dexamethasone acetate, 1 mg) or dexamethasone sodium phospate (J1100, Injection, dexamethasone sodium phosphate, 1mg). You might need to change the dexamethasone code on your claim. In addition, J2010 (Injection, lincomycin hcl, up to 300 mg) is for the antibiotic Lincomycin, not the local anesthetic lidocaine. The only HCPCS code for lidocaine is J2001 (Injection, lidocaine HCl for intravenous infusion, 10 mg), which is for IV administration only. As noted above, most payers don't separately reimburse for the local anesthetic used in injections. Whether you transposed the digits "0" and "1" on your claim and reported Lincomycin by mistake or whether you reported Lidocaine, the payer probably won't reimburse. If the claim is for a Medicare patient, remember that Medicare doesn't accept any of the HCPCS "S" codes such as S0020. If you want to bill bupivacaine to Medicare, you would need to use submit J3490 (Unclassified drugs). However, most Medicare contractors do not pay separately for bupivacaine (Marcaine) unless it is in an implanted infusion pump.
