Code Description

ICD-10 A54.85 is a billable code used to indicate a diagnosis of gonococcal peritonitis.

Key Diagnostic Point:

Gonococcal peritonitis is a rare but serious complication of gonorrhea, a sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae. This condition occurs when the bacteria spread to the peritoneal cavity, leading to inflammation of the peritoneum, which is the lining of the abdominal cavity. Patients may present with acute abdominal pain, fever, nausea, vomiting, and signs of peritoneal irritation. Diagnosis is typically made through clinical evaluation, supported by laboratory tests that confirm the presence of Neisseria gonorrhoeae in body fluids. Gonococcal peritonitis is more common in individuals with a history of pelvic inflammatory disease (PID) or those who engage in high-risk sexual behaviors. Prompt recognition and treatment are crucial to prevent severe complications, including sepsis and peritonitis-related morbidity. Treatment usually involves the administration of appropriate antibiotics, often in combination, to effectively eradicate the infection. Public health measures, including contact tracing and education about safe sexual practices, are essential to control the spread of gonorrhea and its complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of sexually transmitted infections and their complications.
  • Differentiation from other types of peritonitis is necessary.
  • Documentation must clearly indicate the gonococcal etiology.
  • Potential for co-infection with other STIs complicates coding.

Audit Risk Factors

  • Inadequate documentation of sexual history.
  • Failure to specify the gonococcal nature of the infection.
  • Misclassification with other types of peritonitis.
  • Lack of supporting lab results confirming Neisseria gonorrhoeae.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of gonococcal infections, improving the accuracy of data collection and treatment tracking. A54.85 provides a clear distinction from other types of peritonitis, facilitating better patient management and public health reporting.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of gonococcal infections, improving the accuracy of data collection and treatment tracking. A54.85 provides a clear distinction from other types of peritonitis, facilitating better patient management and public health reporting.
