Your new sentence only talks about patients coming for treatment. Patients can also come to the clinic for diagnosis or assessment, including after-treatment follow-up/assessmment.
What does `assessment' mean here?
Please explain it.

Another synonym for assessment is 'evaluation'.
A patient's condition can be assessed/evaluated. Whether or not there is any need for (further) treatment, tests, etc. might be based on such an evaluation.
I'd rather say evaluation than check up.
