(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Factors influencing health status and contact with health services - Persons with potential health hazards related to communicable diseases Chapter 20: Factors influencing health status and contact with health services Feed
Contact with and (suspected) exposure to other viral communicable diseases.
Modifiers do not apply to ICD-10 codes.
Medical necessity is established by the potential for exposure to a communicable disease, necessitating monitoring for disease development and preventative interventions.Documentation must support the clinical rationale for the encounter.
The clinical responsibility is to assess the patient's exposure risk, monitor for symptoms, and provide appropriate preventative measures (e.g., testing, quarantine recommendations).

In simple words: This code means the patient might have been exposed to a viral illness, but doesn't show any symptoms yet. Doctors use it to track people who may have been near someone with a contagious virus.
This ICD-10-CM code signifies contact with or suspected exposure to viral communicable diseases not elsewhere classified.It's used when a patient has had close personal contact with an infected individual or is in an area experiencing an epidemic of a viral communicable disease, but does not show signs or symptoms of the disease.The code is for monitoring potential disease development or implementing preventive measures.It should not be used if the patient is diagnosed with the viral communicable disease; other codes are designated for confirmed cases.
Example 1: A patient presents to the clinic after having been in close contact with a family member diagnosed with influenza.The patient is asymptomatic but requests a flu test and preventive measures., A healthcare worker reports potential exposure to measles in a hospital setting.The worker is asymptomatic, but the code is used for monitoring and potential preventative care., A patient travels to a region experiencing a mumps outbreak and seeks evaluation for potential exposure, despite currently being asymptomatic.
Documentation should include details of the suspected exposure, such as the date, time, and nature of contact with the infected individual or location of the outbreak.Note the absence of symptoms in the patient and any preventative measures taken (e.g., testing, vaccination).
** This code should be used cautiously and only when there is a credible suspicion of exposure.It is crucial to differentiate between suspected exposure and a confirmed diagnosis of a viral communicable disease.
