How would you code this headache stiffneck and fever due to meningitis?

To code a headache, stiff neck, and fever due to meningitis, you would use the appropriate ICD-10 codes. For meningitis, you would typically use G00-G09 for central nervous system infections, specifying the type of meningitis (e.g., viral or bacterial). Additionally, you would code the symptoms using R51 for headache, M54.2 for cervicalgia (stiff neck), and R50 for fever. It's important to ensure that the primary diagnosis reflects the underlying condition (meningitis) while including the symptom codes as secondary diagnoses.
