Congenital syphilis (A50)

Browse all the diagnosis codes used for congenital syphilis (a50). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Longitudinal Studies - Studies in which variables relating to an individual or group of individuals are assessed over a period of time.

Neurosyphilis - Infections of the central nervous system caused by TREPONEMA PALLIDUM which present with a variety of clinical syndromes. The initial phase of infection usually causes a mild or asymptomatic meningeal reaction. The meningovascular form may present acutely as BRAIN INFARCTION. The infection may also remain subclinical for several years. Late syndromes include general paresis; TABES DORSALIS; meningeal syphilis; syphilitic OPTIC ATROPHY; and spinal syphilis. General paresis is characterized by progressive DEMENTIA; DYSARTHRIA; TREMOR; MYOCLONUS; SEIZURES; and Argyll-Robertson pupils. (Adams et al., Principles of Neurology, 6th ed, pp722-8)

Syphilis - A contagious venereal disease caused by the spirochete TREPONEMA PALLIDUM.

Syphilis Serodiagnosis - Serologic tests for syphilis.

Syphilis, Cardiovascular - Cardiovascular manifestations of SYPHILIS, an infection of TREPONEMA PALLIDUM. In the late stage of syphilis, sometimes 20-30 years after the initial infection, damages are often seen in the blood vessels including the AORTA and the AORTIC VALVE. Clinical signs include syphilitic aortitis, aortic insufficiency, or aortic ANEURYSM.

Syphilis, Congenital - Syphilis acquired in utero and manifested by any of several characteristic tooth (Hutchinson's teeth) or bone malformations and by active mucocutaneous syphilis at birth or shortly thereafter. Ocular and neurologic changes may also occur.

Syphilis, Cutaneous - Cutaneous lesions arising from infection with Treponema pallidum. In the primary stage, 18-21 days following infection, one or more chancres appear. If untreated, the subsequent stages of the disease appear as syphilids. These eruptions are superficial, nondestructive, exanthematic, transient, macular roseolas that may later be maculopapular or papular polymorphous or scaly, pustular, pigmented eruptions.(Arnold, Odom, and James, Andrew's Diseases of the Skin, 8th ed, p409)

Syphilis, Latent - The stage of syphilis that occurs following the primary (CHANCRE) and secondary stages. The patient is asymptomatic at the latent stage but remains seropositive for the SPIROCHETE.

Tabes Dorsalis - Parenchymatous NEUROSYPHILIS marked by slowly progressive degeneration of the posterior columns, posterior roots, and ganglia of the spinal cord. The condition tends to present 15 to 20 years after the initial infection and is characterized by lightening-like pains in the lower extremities, URINARY INCONTINENCE; ATAXIA; severely impaired position and vibratory sense, abnormal gait (see GAIT DISORDERS, NEUROLOGIC), OPTIC ATROPHY; Argyll-Robertson pupils, hypotonia, hyperreflexia, and trophic joint degeneration (Charcot's Joint; see ARTHROPATHY, NEUROGENIC). (From Adams et al., Principles of Neurology, 6th ed, p726)

Treponema pallidum - The causative agent of venereal and non-venereal syphilis as well as yaws.
