Code Description

ICD-10 A52.17 is a billable code used to indicate a diagnosis of general paresis.

Key Diagnostic Point:

General paresis is a late manifestation of untreated syphilis, characterized by progressive neurological decline due to the infection's impact on the central nervous system. It typically presents with a combination of psychiatric symptoms, cognitive impairment, and motor dysfunction. Patients may exhibit personality changes, emotional instability, and cognitive deficits, including memory loss and difficulty concentrating. Neurologically, they may experience tremors, seizures, and other motor disturbances. The condition arises from the chronic effects of Treponema pallidum, the bacterium responsible for syphilis, leading to inflammation and damage in the brain and spinal cord. Diagnosis is often confirmed through serological testing for syphilis, alongside clinical evaluation of neurological symptoms. Treatment involves the administration of antibiotics, primarily penicillin, which can halt the progression of the disease but may not reverse existing neurological damage. Early detection and treatment of syphilis are crucial in preventing the development of general paresis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of syphilis progression and its neurological implications.
  • Differentiation from other neurological disorders is necessary.
  • Documentation must include both psychiatric and neurological assessments.
  • Treatment protocols may vary based on the stage of syphilis and patient response.

Audit Risk Factors

  • Inadequate documentation of neurological and psychiatric evaluations.
  • Failure to document the history of syphilis infection.
  • Lack of clarity in treatment plans and patient follow-up.
  • Misclassification of symptoms as unrelated neurological disorders.

Specialty Focus

Neurology

Documentation Requirements

Detailed neurological examination findings, including cognitive assessments and motor function tests.

Common Clinical Scenarios

Patients presenting with cognitive decline, personality changes, or seizures with a history of syphilis.

Billing Considerations

Neurologists must ensure comprehensive documentation of both neurological and psychiatric symptoms for accurate coding.

Infectious Disease

Documentation Requirements

History of syphilis treatment, serological test results, and treatment response.

Common Clinical Scenarios

Patients with a known history of syphilis presenting with neurological symptoms.

Billing Considerations

Infectious disease specialists should document the timeline of syphilis treatment and any complications.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like general paresis, improving the accuracy of diagnoses and treatment tracking. It emphasizes the need for detailed documentation of both psychiatric and neurological symptoms.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conditions like general paresis, improving the accuracy of diagnoses and treatment tracking. It emphasizes the need for detailed documentation of both psychiatric and neurological symptoms.

Frequently Asked Questions

What is the primary cause of general paresis?

General paresis is primarily caused by untreated syphilis, specifically the chronic effects of the Treponema pallidum bacterium on the central nervous system.
