Code Description

ICD-10 N83.312 is a billable code used to indicate a diagnosis of acquired atrophy of left ovary.

Key Diagnostic Point:

Acquired atrophy of the left ovary refers to the reduction in size and function of the left ovary due to various pathological conditions rather than congenital factors. This condition can arise from several underlying issues, including hormonal imbalances, chronic inflammatory processes, or surgical interventions such as oophorectomy or hysterectomy. In women with endometriosis, the presence of endometrial tissue outside the uterus can lead to inflammation and scarring, potentially affecting ovarian function. Additionally, conditions such as female genital prolapse may indirectly contribute to ovarian atrophy due to altered pelvic anatomy and blood supply. Fistulas, particularly those involving the reproductive tract, can also lead to complications that may affect ovarian health. Ovarian disorders, including polycystic ovary syndrome (PCOS) and premature ovarian failure, can further complicate the clinical picture. Accurate diagnosis often requires imaging studies and hormonal assessments to evaluate ovarian size and function, as well as to rule out other conditions that may mimic or coexist with acquired atrophy.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acquired atrophy and congenital conditions
  • Need for comprehensive patient history and documentation of underlying causes
  • Potential overlap with other ovarian disorders and conditions
  • Variability in clinical presentation and diagnostic criteria

Audit Risk Factors

  • Inadequate documentation of the underlying cause of atrophy
  • Misclassification of atrophy as a congenital condition
  • Failure to document associated conditions such as endometriosis or prolapse
  • Inconsistent use of diagnostic imaging results
