Lyme borreliosis
Description
A tick-borne infection by the spirochaete Borrelia burgdorferi. Lyme borreliosis typically presents with a characteristic rash, erythema chronicum migrans, at an average of seven days after a bite from an infected tick. The rash may be accompanied by flu-like symptoms. Disseminated infection may cause meningitis, cranial neuropathies and carditis amongst other manifestations. Late disease, months to years after initial infection, may present with a pauciarticular arthritis or with encephalomyelitis.
Coding note
Use additional code if desired, to identify any associated condition. Use additional code, if desired, to identify any sequelae. The extension code 'Cause of late effect' is used in addition to both codes to show the relationship between the causative condition and the resulting sequelae.
