Code Description

ICD-10 N83.331 is a billable code used to indicate a diagnosis of acquired atrophy of right ovary and fallopian tube.

Key Diagnostic Point:

Acquired atrophy of the right ovary and fallopian tube refers to the degeneration or shrinkage of these reproductive structures, often resulting from various underlying conditions such as endometriosis, pelvic inflammatory disease, or previous surgical interventions. This atrophy can lead to hormonal imbalances, infertility, and other reproductive health issues. In cases of endometriosis, the presence of endometrial-like tissue outside the uterus can cause inflammation and scarring, potentially affecting the ovaries and fallopian tubes. Female genital prolapse may also contribute to the atrophy by altering the anatomical position and function of these organs. Additionally, fistulas, ovarian disorders, and polyps in the female genital tract can complicate the clinical picture, leading to further atrophy due to chronic inflammation or obstruction. Accurate diagnosis often requires imaging studies and a thorough clinical evaluation to assess the extent of atrophy and its impact on reproductive health.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acquired atrophy and other ovarian disorders
  • Understanding the relationship with endometriosis and pelvic inflammatory disease
  • Identifying associated conditions such as fistulas and polyps
  • Documenting the clinical significance of atrophy in relation to fertility

Audit Risk Factors

  • Inadequate documentation of the clinical rationale for the diagnosis
  • Failure to document associated conditions that may affect coding
  • Misidentification of the affected side (right vs. left)
  • Lack of supporting imaging or surgical reports
