I work at an Oncology practice and we have many patients that come in every week for injections only. First, this DOES have to be documented in the patient's chart. Period! If you are ever audited and have no documentation in the patient's chart in regards to a service was performed, not only will you have to give back every dollar you were paid, you would be subject to huge fines and penalties. Very bad.
But, we're not talking about a dictated note here or anything. We have a "flow sheet" for our injections where at the top of the page it has the patient's info- name, dob, chart #, what drug is being injected and the diagnosis for why they are receiving the injection. Then underneath are columns for each visit where the date of service, patient's vitals (weight, bp and temp), dose, injection site and time are documented along with the nurses initials. There are probably 20 lines on each side of the page, so this way we have a clear record of what service was performed for each injection. We do this for ALL our injections, even when it is the patient's own supply. For injections like Procrit, we also note the hct/hgb level which shows the medical necessity for the injection.
