Tune in to this monthly online coding column to learn from AHIMA’s coding experts about challenging areas and documentation opportunities for ICD-10-CM/PCS.
Zika virus is a mosquito-borne virus that was first identified in Uganda in 1947 in rhesus monkeys. There has recently been a rise in incidences of the Zika virus in Brazil. More than 13 countries in the Americas have reported sporadic Zika virus infections, indicating that the virus is expanding geographically. You can read more facts about the Zika virus on the World Health Organization (WHO) website.
It’s important for coders to recognize the integral signs and symptoms of Zika. Here is the list from the Centers for Disease Control and Prevention (CDC):
- Most common symptoms: fever, rash, joint pain, or conjunctivitis
- Other common symptoms: muscle pain and headache
- Symptoms are typically mild and last from several days to a week
- The virus can remain in the blood of an infected person for a few days
- Hospitalization is uncommon
- Deaths are rare
- There have been reports of microcephaly and other poor pregnancy outcomes in babies of mothers who were infected with Zika virus while pregnant
ICD-10-CM Coding for Zika
Per the CDC, the correct code for confirmed Zika virus infection is A92.8, Other specified mosquito-borne viral fevers. Further guidance on correct coding in various clinical scenarios will be forthcoming from the CDC and posted to the CDC website. Be on the lookout for more information.
Has your facility seen any incidences of the Zika virus? Are there other conditions, such as Zika, where you struggle with finding the appropriate code?
