Ornithosis with other specified complications

This code signifies psittacosis (ornithosis), a zoonotic infection caused by Chlamydia psittaci, when it presents with complications beyond typical respiratory symptoms. These complications can affect various organ systems, such as the cardiovascular, neurological, or hepatic systems. It indicates a more severe or disseminated form of the infection.

Use this code when documentation clearly states a diagnosis of ornithosis accompanied by specific non-pulmonary complications, such as myocarditis, encephalitis, hepatitis, or thrombophlebitis attributed to the infection. The physician's notes should explicitly link these complications to the ornithosis.

• Ensure the documentation specifies the "other specified complication" to justify using this code over a simpler ornithosis code.
• Do not use this code for uncomplicated ornithosis, which would typically involve only respiratory symptoms.
• Consider sequencing this code as the primary diagnosis if the ornithosis and its complication are the main reason for the encounter, followed by codes for the specific complication if further detail is needed.
