Nocardiosis is an infectious disease caused by the Nocardia species, primarily affecting immunocompromised individuals. It can lead to pulmonary, cutaneous, or disseminated infections. Accurate coding with ICD-10 Code A43.9 ensures proper diagnosis, documentation, and billing, facilitating effective public health reporting and resource allocation.
What is ICD-10 Code A43.9 for Nocardiosis, unspecified?
ICD-10 Code A43.9 represents Nocardiosis, unspecified, indicating an infection caused by Nocardia species without specific details on the site or severity. This code is used when the clinical presentation does not specify the type of nocardiosis, ensuring appropriate documentation and billing in cases of suspected or confirmed infection.
ICD-10 Code A43.9 – Clinical Definition and Explanation of Nocardiosis, unspecified
Nocardiosis is caused by the Nocardia bacteria, which can be found in soil and decaying organic matter. The infection typically occurs in immunocompromised patients, leading to serious complications if untreated. Prompt diagnosis and treatment are essential to prevent progression and potential mortality.
Key Clinical Features:
- Pulmonary symptoms such as cough and dyspnea
- Skin lesions or abscesses
- Fever and malaise
- Potential for dissemination to the central nervous system
ICD-10 Code A43.9 for Nocardiosis, unspecified – SOAP Notes & Clinical Use
ICD-10 Code A43.9 is utilized in SOAP notes to document the patient's symptoms, assessment findings, and treatment plans. It is relevant in both acute and chronic care settings, ensuring comprehensive documentation of the patient's condition and facilitating appropriate management.
What Does ICD-10 Code A43.9 for Nocardiosis, unspecified Mean in SOAP Notes?

- Imipenem or meropenem as alternatives in severe cases
- Amikacin may be added for resistant strains
- Linezolid for patients with intolerance to first-line agents
Supportive Care:
- Monitor respiratory status and oxygenation
- Manage fever and pain with appropriate medications
- Provide nutritional support as needed
- Educate patients on infection prevention
Infection Control:
- Implement standard precautions to prevent transmission
- Isolate patients with disseminated disease if necessary
- Educate healthcare staff on handling infectious materials
- Monitor for outbreaks in healthcare settings
How to Document Symptoms of Nocardiosis, unspecified (ICD-10 A43.9) in SOAP Notes
Subjective:
- Patient reports persistent cough and shortness of breath
- History of skin lesions noted by the patient
- Fever and fatigue experienced over the past week
- Recent travel to areas with known Nocardia exposure
Objective:
- Auscultation reveals crackles in the lungs
- Temperature recorded at 101°F
- Skin examination shows multiple nodular lesions
- Chest X-ray indicates possible pulmonary nodules
