ok, im not an expert in home health billing, but i believe you would bill the date span (09/01/09-09/25/09) and use the app hcpcs (A6219) and use the units would be 24. If the cost is .14cents then it would be a charge of 3.36. If I am not mistaken you won't need the NU mod on the commercial payors. please feel free to email me if you need to. I can give you some links to sites that would help. As stated I don't do home health, but I do do DME-custom rehab.
dates and codes are just examples.
