Question: My physician gave a patient a 10 mg injection of vitamin K. How should I report this? Texas Subscriber Answer: You should report 96372 (Therapeutic, prophylactic, or diagnostic injection [specify substance or drug]; subcutaneous or intramuscular) for the injection. For the vitamin K itself, you’ll use J3430 (Injection, phytonadione [vitamin K], per 1 mg). Then place 10 in the units column because your physician gave a 10 mg injection, and the code is reportable per 1 mg.
