Old method: CPT lumps hydration therapy with other non-chemotherapeutic infusion under 90780 (Intravenous infusion for therapy/diagnosis, administered by physician or under direct supervision of physician; up to one hour). New method: You can specifically code intravenous (IV) infusion to hydrate a patient with G0345, and when appropriate G0346. Choose the code based on the IV infusion's length:
up to one hour - G0345 (Intravenous infusion, hydration; initial, up to one hour)
each additional hour after the first - G0346 (Each additional hour, up to eight  hours [list separately in addition to code for primary procedure]). Change Carrier 90782 Coding to G0351 You should also use a G code when a Medicare patient receives a therapeutic, prophylactic or diagnostic injection.
2004 method: Code 90782 (Therapeutic, prophylactic or diagnostic injection [specify material injected]; subcutaneous or intramuscular) previously described these types of injections.
2005 method: You should now report the injection with G0351 (Therapeutic or diagnostic injection [specify substance or drug]; subcutaneous or intramuscular), says Mary Falbo, MBA, CPC, president of Millennium Healthcare Consulting Inc., a healthcare consulting firm based in Landsdale, Pa.
You should replace 90782 with G0351 when the provider administers: a B-12 injection (also use J3420 for the B-12 itself)
a restorative treatment, like Decadron for croup.
Payment alert: You should report G0345-G0346 and G0351 to Medicare carriers only. Medicare created these codes to comply with the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (MMA), Falbo says. Although the AMA formed a CPT Editorial Panel that revamped the codes, the panel did not complete the changes in time for CPT 2005.
CMS, however, incorporated the changes this year. "New CPT codes will exist in 2006 for all to use, but right now practices are to use the G codes for Medicare only," Falbo says.
Use Dose-Specific Nebulizer Medicine J Codes While you're updating your infusion codes, make sure to add four new nebulizer medication codes. HCPCS 2005 deletes the codes you previously used to report nebulizer medications: J7618-J7619.
New way: You should now assign: J7611 - Albuterol, inhalation solution, administered through DME, concentrated form, 1 mg
J7612 - Levalbuterol, inhalation solution, administered through DME, concentrated form, 0.5 mg
J7613 - Albuterol, inhalation solution, administered through DME, unit dose, 1 mg
J7614 - Levalbuterol, inhalation solution, administered through DME, unit dose, 0.5 mg. Benefit: "The new [...]
