ICD-10 Code A39.51 | Meningococcal endocarditis Symptoms, Diagnosis, Billing

Common symptoms include fever, chills, fatigue, chest pain, and new heart murmurs. Patients may also present with signs of embolic phenomena such as petechiae.

Treatment typically involves intravenous antibiotics such as ceftriaxone or penicillin G, along with supportive care and monitoring for complications.

While Neisseria meningitidis can be transmitted through respiratory droplets, meningococcal endocarditis itself is not directly contagious. Close contacts may require prophylactic antibiotics.

This code should be used when documenting cases of endocarditis specifically caused by Neisseria meningitidis, ensuring accurate representation for billing and clinical documentation.
