Coding Tips

• •Verify documentation confirms epidemic/outbreak context and viral etiology before assigning this code; isolated vertigo cases may require different coding
• •This code is specifically for the epidemic form of vertigo; if the patient has non-epidemic vertigo or the outbreak status is unclear, consider alternative vertigo codes like R42 or other specified vertigo codes
