2025 ICD-10-CM code A49.3
(Active) Effective Date: N/A Infectious and parasitic diseases - Other bacterial diseases Certain infectious and parasitic diseases Feed
Mycoplasma infection of unspecified site.
Medical necessity is established by the confirmed presence of Mycoplasma infection impacting the patient's health, as evidenced by clinical findings and diagnostic testing.The unspecified site implies the inability to pinpoint a more specific location despite diagnostic efforts.
Clinicians should document the patient's symptoms (e.g., fever, cough, sore throat, headache, fatigue), physical findings, and results of laboratory tests (e.g., cultures, chest X-ray or CT scan) to support the diagnosis of a mycoplasma infection. Treatment may involve antibiotics (oral or IV) and supportive care such as oxygen and intravenous fluids.
In simple words: This code indicates an infection with mycoplasma bacteria, but the doctor hasn't identified exactly where in the body the infection is located.
This code represents a mycoplasma infection where the specific site of infection is not documented or specified.It encompasses infections caused by bacteria of the genus Mycoplasma, excluding infections with specified sites.
Example 1: A patient presents with fever, cough, and fatigue.Laboratory tests confirm a mycoplasma infection, but the precise location is undetermined, thus A49.3 is used., A patient with generalized symptoms consistent with mycoplasma infection undergoes various tests. While the tests confirm mycoplasma, they do not pinpoint a specific site of infection. A49.3 is appropriate in this case., A patient is admitted with respiratory symptoms and is diagnosed with mycoplasma infection after lab work.However, imaging and other tests do not localize the infection to a specific part of the respiratory system.A49.3 is assigned.
Documentation should include signs, symptoms, and laboratory results confirming Mycoplasma infection. If the site of infection is later identified, a more specific code should be used.
