The quote above is from a response to a similar question posted under the title
Modifier(s) for Use of Interpreter During Visit. You cannot charge the patient for the use of the interpreter or for services to translate documents into their primary language.
While you cannot bill for the use of the interpreter, the fact that the length of the visit is extended due to the process of interpreting the conversation, you may be able to include the time spent conversing with the patient via an interpreter towards to the total time for the visit if you are billing for E&M services that have a time component. Then you could consider coding these visits based on time if the provider is documenting the exact amount of time they personally spent on the date of the encounter providing care to the patient, both face-to-face and non-face-to-face. This may mean you end up billing for prolonged visits services in addition to 99205 or 99215 since they have a time component to them.
There is no time component to preventive E&Ms and in office procedures so there is no way to capture the additional expense to the practice for patients who require an interpreter, for those types of visits it is just part of the cost of doing business.
I'm not an expert on E&M coding so I don't know for sure if this is the case so, please check with someone you trust who can guide you on E&M coding based on time and whether the time added to the visit due to the use of the interpreter is appropriate or not.
