Late syphilitic oculopathy

Code Description

ICD-10 A52.71 is a billable code used to indicate a diagnosis of late syphilitic oculopathy.

Key Diagnostic Point:

Late syphilitic oculopathy is a severe manifestation of syphilis that occurs in the tertiary stage of the disease, typically years after the initial infection. This condition is characterized by ocular complications that can lead to significant vision impairment or blindness. The pathophysiology involves the infiltration of Treponema pallidum, the bacterium responsible for syphilis, into ocular tissues, resulting in inflammation and damage to various structures of the eye, including the retina, choroid, and optic nerve. Symptoms may include blurred vision, visual field defects, and ocular pain. Diagnosis is primarily clinical, supported by serological tests for syphilis, such as the RPR (Rapid Plasma Reagin) and FTA-ABS (Fluorescent Treponemal Antibody Absorption) tests. Treatment typically involves high-dose penicillin therapy, which can halt the progression of the disease but may not reverse existing damage. Regular follow-up with an ophthalmologist is essential for monitoring and managing any visual complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of syphilis stages and their implications.
  • Differentiation from other ocular conditions is necessary.
  • Documentation must include specific ocular symptoms and serological test results.
  • Potential for co-morbidities that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of ocular symptoms.
  • Failure to include serological test results.
  • Misclassification of the stage of syphilis.
  • Lack of follow-up documentation.
