I'm hoping someone can help my mind with its internal debate. As we know history codes cannot be used solo or as primary. For my DVT patients when they come for their yearly follow up and are on therapeutic dosing of medications as preventative measure my providers are using the history of codes for the appointment. Would Z09 be suitable as the primary diagnosis code, or should I add back in the original DVT code with the history code? Technically they don't have a DVT but now they are on a lower dose of the medication for the preventative measure so will that still fit into the Z09 description?
