Code Description

ICD-10 A52.05 is a billable code used to indicate a diagnosis of other cerebrovascular syphilis.

Key Diagnostic Point:

Other cerebrovascular syphilis refers to a rare manifestation of syphilis that affects the cerebrovascular system, leading to complications such as stroke or transient ischemic attacks (TIAs). This condition arises from the systemic spread of Treponema pallidum, the bacterium responsible for syphilis, which can invade the central nervous system (CNS) and cause vascular damage. Patients may present with neurological symptoms, including headaches, seizures, or focal neurological deficits. Diagnosis typically involves serological testing for syphilis, along with imaging studies such as MRI or CT scans to assess cerebrovascular involvement. Treatment primarily consists of antibiotic therapy, usually with penicillin, which is effective in eradicating the infection and preventing further neurological damage. Early detection and treatment are crucial to minimize long-term complications and improve patient outcomes. Given the complexities of syphilis transmission and its potential to affect multiple organ systems, healthcare providers must maintain a high index of suspicion for cerebrovascular syphilis in patients with a history of syphilis and neurological symptoms.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of syphilis transmission and its neurological manifestations.
  • Involves differentiating from other cerebrovascular conditions.
  • Documentation must clearly link symptoms to syphilis diagnosis.
  • Requires knowledge of appropriate serological tests and imaging studies.

Audit Risk Factors

  • Inadequate documentation linking cerebrovascular symptoms to syphilis.
  • Failure to perform or document necessary serological tests.
  • Misinterpretation of imaging results leading to incorrect coding.
  • Inconsistent coding practices across different providers.
