Code Description

ICD-10 A58 is a billable code used to indicate a diagnosis of granuloma inguinale.

Key Diagnostic Point:

Granuloma inguinale, also known as donovanosis, is a sexually transmitted infection caused by the bacterium Calymmatobacterium granulomatis. It is characterized by the development of painless, progressive ulcerative lesions primarily in the genital and perianal regions. The lesions are typically beefy red and can bleed easily upon contact. The condition is endemic in certain tropical and subtropical regions, but cases have been reported worldwide, particularly among populations with high rates of sexually transmitted infections (STIs). Diagnosis is often made through clinical examination and can be confirmed by identifying the causative organism in tissue samples. Granuloma inguinale is associated with other STIs, necessitating comprehensive screening and treatment of sexual partners. Treatment typically involves antibiotics, with azithromycin being the first-line therapy. Early intervention is crucial to prevent complications such as secondary infections and scarring. Contact tracing is essential to control the spread of the infection, as it is highly transmissible through sexual contact.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of sexually transmitted infections and their coding nuances.
  • Differentiation from other ulcerative genital conditions.
  • Need for accurate documentation of clinical findings.
  • Potential for co-infection with other STIs.

Audit Risk Factors

  • Inadequate documentation of clinical findings.
  • Failure to document patient history of STIs.
  • Lack of evidence for contact tracing efforts.
  • Misclassification of the condition with other ulcerative diseases.

Coding Guidelines

Inclusion Criteria

Use A58 When
  • According to ICD
  • 10 guidelines, A58 should be used when granuloma inguinale is confirmed
  • Coders should ensure that the diagnosis is supported by clinical findings and laboratory results

Exclusion Criteria

Do NOT use A58 When
  • Exclusion criteria include conditions that present with similar symptoms but are not caused by Calymmatobacterium granulomatis

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of granuloma inguinale, improving the accuracy of data collection and epidemiological tracking of this STI. It has also enhanced the ability to capture co-morbid conditions and complications associated with the infection.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of granuloma inguinale, improving the accuracy of data collection and epidemiological tracking of this STI. It has also enhanced the ability to capture co-morbid conditions and complications associated with the infection.

Reimbursement & Billing Impact

Frequently Asked Questions

What are the common symptoms of granuloma inguinale?

Common symptoms include painless ulcers in the genital area, which may bleed easily. The lesions are typically beefy red and can progress if untreated.

How is granuloma inguinale treated?

Granuloma inguinale is treated with antibiotics, with azithromycin being the first-line treatment. Other options include doxycycline and ciprofloxacin.

Is granuloma inguinale contagious?

Yes, granuloma inguinale is highly contagious and is primarily transmitted through sexual contact. Contact tracing is essential to prevent further spread.
