Code Description

ICD-10 N83.33 is a billable code used to indicate a diagnosis of acquired atrophy of ovary and fallopian tube.

Key Diagnostic Point:

Acquired atrophy of the ovary and fallopian tube refers to the degeneration and reduction in size of these reproductive organs, often resulting from various pathological conditions. This atrophy can be secondary to hormonal imbalances, chronic inflammatory processes, or surgical interventions. In the context of endometriosis, the presence of ectopic endometrial tissue can lead to inflammation and scarring, which may compromise ovarian function and lead to atrophy. Female genital prolapse can also contribute to altered blood flow and mechanical stress on the ovaries and fallopian tubes, exacerbating atrophic changes. Additionally, fistulas, particularly those resulting from pelvic surgeries or severe endometriosis, can disrupt normal anatomical relationships and blood supply, further promoting atrophy. Ovarian disorders, such as polycystic ovary syndrome (PCOS) or premature ovarian failure, may also play a role in the acquired atrophy of these structures. Polyps in the female genital tract can lead to obstructive processes that may indirectly affect ovarian health. Understanding the multifactorial nature of this condition is crucial for accurate diagnosis and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acquired atrophy and congenital conditions
  • Understanding the underlying causes such as endometriosis and pelvic inflammatory disease
  • Documenting associated conditions like ovarian disorders and polyps
  • Navigating the interplay between surgical history and atrophy

Audit Risk Factors

  • Inadequate documentation of the underlying causes of atrophy
  • Failure to link atrophy with relevant surgical history
  • Misclassification of atrophy as a congenital condition
  • Lack of clarity in distinguishing between atrophy and other ovarian disorders

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed history of menstrual cycles, surgical history, and any previous diagnoses of endometriosis or ovarian disorders.

Common Clinical Scenarios

Patients presenting with pelvic pain, infertility, or abnormal imaging findings related to ovarian size.

Billing Considerations

Ensure that all relevant diagnostic tests (e.g., ultrasound, MRI) are documented to support the diagnosis of atrophy.

Reproductive Endocrinology

Documentation Requirements

Comprehensive hormonal assessments and fertility evaluations.

Common Clinical Scenarios

Patients with unexplained infertility or hormonal imbalances presenting with signs of ovarian dysfunction.

Billing Considerations

Document any hormonal treatments or interventions that may impact ovarian health.

Coding Guidelines

Inclusion Criteria

Use N83.33 When
  • According to ICD
  • 10 guidelines, N83
  • 33 should be used when atrophy is acquired and not congenital
  • It is important to document the specific cause of atrophy, such as endometriosis or surgical history, to ensure accurate coding

Exclusion Criteria

Do NOT use N83.33 When
  • Exclusion criteria include congenital atrophy or atrophy due to malignancy

Laparoscopy, surgical, with ablation of endometriosis

Clinical Scenario

Used in cases where endometriosis is identified as a cause of atrophy.

Documentation Requirements

Operative reports detailing the findings and procedures performed.

Specialty Considerations

Gynecologists should ensure that the surgical findings correlate with the diagnosis of atrophy.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like acquired atrophy, enabling better tracking of patient outcomes and treatment efficacy. This specificity aids in research and improves the understanding of the condition's prevalence and associated factors.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conditions like acquired atrophy, enabling better tracking of patient outcomes and treatment efficacy. This specificity aids in research and improves the understanding of the condition's prevalence and associated factors.
