Answer:
False.
Step-by-step explanation:
In a situation where the original treatment plan or procedure cannot be carried out due to unforeseen circumstances, the criteria for designation of the principal diagnosis can change. The principal diagnosis should reflect the condition that is primarily responsible for the admission of the patient. If the original planned treatment was not carried out and a different condition becomes the primary reason for the admission, that condition should be designated as the principal diagnosis. The principal diagnosis should accurately reflect the reason for the patient's admission and the main condition requiring medical attention.
