ICD-10 Code Z20.828
Contact with and (suspected) exposure to other viral communicable diseases
What is the code Z20.828?
The ICD-10-CM code Z20.828 refers to "contact with and (suspected) exposure to other viral communicable diseases." This code is used when documenting instances where a patient has been in contact with or is suspected to have been exposed to viral diseases not specifically classified elsewhere.
Detailed description of Z20.828
Use code Z20.828 to indicate that a patient has been exposed to a viral communicable disease. This code is particularly significant in scenarios where there is a need to monitor the patient for potential development of the disease or to implement preventive measures. It is a part of the broader category of codes that deal with encounters for health services specifically related to potential health hazards due to communicable diseases.
Symptoms commonly associated with Z20.828
Since Z20.828 pertains to exposure rather than a confirmed diagnosis, it does not inherently link to specific symptoms. Instead, it indicates that the patient may need to be observed for symptoms related to the particular viral disease to which they were exposed. Symptoms will vary widely depending on the specific virus in question, ranging from respiratory symptoms, gastrointestinal issues, to skin rashes, among others.

- Z20.822: Contact with and (suspected) exposure to measles
- Z20.823: Contact with and (suspected) exposure to mumps
- Z20.824: Contact with and (suspected) exposure to rubella
Appropriate usage of Z20.828 for billing
When using Z20.828 for billing purposes, the provider should document, in the assessment portion of the note, the patient's exposure to a specific viral communicable disease. Use this code during encounters where the primary reason for the visit is the exposure itself, rather than the manifestation of symptoms or the treatment of a confirmed disease.
Instructional notes and/or guidelines with Z20.828
- Primary code usage: List Z20.828 as a primary diagnosis if the main reason for the visit is the exposure to the viral disease.
- Secondary code usage: Use Z20.828 as a secondary code if the exposure is a pertinent part of the patient's health history but not the primary reason for the visit.
- Documentation: Ensure detailed documentation of the exposure circumstances, including the type of virus and the context of exposure.
- Exclusions: Do not use Z20.828 if the patient has a confirmed diagnosis of the viral disease; in such cases, use the specific code for the confirmed condition.
Common pitfalls in coding with Z20.828
- Incorrect primary diagnosis: Using Z20.828 as a primary diagnosis when the patient is being treated for symptoms or a confirmed disease rather than exposure.
- Lack of detailed documentation: Failing to provide sufficient details regarding the exposure, which can lead to claim denials or issues with medical record accuracy.
- Misuse with confirmed diagnoses: Using Z20.828 for patients with a confirmed diagnosis of the viral disease instead of the specific code for the disease itself.
Key resources for Z20.828 coding
- ICD-10-CM Official Guidelines for Coding and Reporting: Provides comprehensive guidelines on the correct usage of ICD-10 codes.
- Centers for Medicare & Medicaid Services (CMS): Offers resources and updates on coding practices.

Conclusion
ICD-10-CM code Z20.828 is used to document and bill for encounters where a patient has been exposed to a viral communicable disease. By adhering to the guidelines and avoiding common pitfalls, healthcare providers can help ensure accurate and efficient coding practices, ultimately supporting better patient care and streamlined operations.
