Medical necessity is established when there is a reasonable belief that a patient has been exposed to water pollution and needs assessment and/or treatment for potential health consequences. The physician’s clinical judgment should be supported by appropriate documentation.
The clinical responsibility for this code involves evaluating the patient for any potential health effects from water pollution exposure.
