Patient "assessment" question

When one of our doctors removes a lesion that they "FEEL" is going to be Squamous,Basal Cell is it ok to put that diagnosis down in the "assessment"? Or should it be coded 238.2. Unspecfied. When they code it as malig then it turns out to just be AK or SK, the patient chart has a wrong diagnosis in it. We wait to actually bill out for the service until the path comes back so it gets sent to the insurance company correct. So does the assessment make much difference since the path will prove what the lesion was?. Sorry if this was confusing wasn't sure how to say what I wanted. Thank you

re: Patient

in reference to your question you should never code a definitive DX with statements as "they feel, could be, may be, I suspect etc" w/out confirmation from the labs. As you stated a patient could have a incorrect DX in their records(can you imaginge being coded for HSV w/out confirmation from the labs,I would freak if i was a patient and it was incorrect). If you cannot wait for the labs, then I would code for the signs and symptoms as per the coding guidelines.
