A42.7

Actinomycotic sepsis

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 A42.7 is a billable code used to indicate a diagnosis of actinomycotic sepsis.

Key Diagnostic Point:

Actinomycotic sepsis is a severe systemic infection caused by Actinomyces species, which are anaerobic bacteria commonly found in the human oral cavity and gastrointestinal tract. This condition typically arises in immunocompromised patients, such as those with HIV/AIDS, diabetes, or those undergoing immunosuppressive therapy. The clinical presentation may include fever, chills, malaise, and localized abscess formation, often in the cervicofacial region, thorax, or abdomen. Diagnosis can be challenging due to the nonspecific nature of symptoms and the difficulty in culturing Actinomyces, which may require specialized media. Imaging studies and histopathological examination are often necessary to confirm the diagnosis. Prompt recognition and treatment are crucial, as actinomycotic sepsis can lead to significant morbidity and mortality if not addressed swiftly. Treatment typically involves prolonged antibiotic therapy, often with penicillin, and may require surgical intervention to drain abscesses or remove necrotic tissue.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Difficulty in diagnosing due to nonspecific symptoms.
  • Need for specialized culture techniques for Actinomyces.
  • Potential for misdiagnosis with other types of sepsis.
  • Documentation requirements for immunocompromised status.

Audit Risk Factors

  • Inadequate documentation of immunocompromised status.
  • Failure to document the source of infection.
  • Lack of specificity in clinical notes regarding symptoms.
  • Improper coding of related conditions or complications.
