Code Description

ICD-10 N61.23 is a billable code used to indicate a diagnosis of granulomatous mastitis, bilateral breast.

Key Diagnostic Point:

Granulomatous mastitis is a rare inflammatory condition of the breast characterized by the formation of granulomas, which are small areas of inflammation. This condition can occur bilaterally, affecting both breasts, and is often associated with a history of breastfeeding or autoimmune diseases. Patients may present with breast lumps, nipple discharge, and localized pain or tenderness. The diagnosis is typically confirmed through imaging studies such as mammography or ultrasound, followed by a biopsy to rule out malignancy. Granulomatous mastitis is considered a benign breast disease, but it can mimic more serious conditions, making accurate diagnosis and coding essential. Treatment may involve corticosteroids or surgical intervention, depending on the severity of symptoms and the extent of the disease. Understanding the clinical presentation and imaging findings is crucial for coders to ensure proper documentation and coding of this condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other types of mastitis and breast diseases
  • Need for imaging studies and biopsy results for accurate diagnosis
  • Potential overlap with malignant conditions requiring careful documentation
  • Variability in clinical presentation among patients

Audit Risk Factors

  • Inadequate documentation of clinical findings and imaging results
  • Failure to document the patient's history of breastfeeding or autoimmune conditions
  • Misclassification of granulomatous mastitis as a malignant condition
  • Lack of follow-up documentation on treatment response

Common symptoms include breast lumps, pain, swelling, and sometimes nipple discharge. Patients may also experience tenderness in the affected areas.

How is granulomatous mastitis diagnosed?

Diagnosis typically involves clinical examination, imaging studies such as ultrasound or mammography, and confirmation through biopsy.

What treatment options are available for granulomatous mastitis?

Treatment may include corticosteroids to reduce inflammation or surgical intervention if necessary. The approach depends on the severity of symptoms and the extent of the disease.
