Code Description

ICD-10 D21.22 is a billable code used to indicate a diagnosis of benign neoplasm of connective and other soft tissue of left lower limb, including hip.

Key Diagnostic Point:

D21.22 refers to benign neoplasms that arise from connective and other soft tissues in the left lower limb, including the hip region. These neoplasms can include a variety of tumors such as lipomas, fibromas, and other soft tissue tumors that are non-cancerous. Clinically, these tumors may present as palpable masses, and patients might report discomfort or pain depending on their size and location. Diagnosis typically involves imaging studies such as ultrasound or MRI to assess the characteristics of the mass, and a biopsy may be performed to confirm the benign nature of the tumor. Management often includes surgical excision, especially if the neoplasm is symptomatic or growing. Follow-up care is essential to monitor for recurrence, although benign tumors generally have a low risk of returning after complete removal. The prognosis for patients with benign neoplasms is typically excellent, with most individuals returning to normal activities post-treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of benign neoplasms that can be coded under this category
  • Need for precise documentation of the tumor's location and characteristics
  • Differentiation from malignant neoplasms in clinical documentation
  • Potential for multiple neoplasms in the same anatomical area

Audit Risk Factors

  • Inadequate documentation of tumor characteristics
  • Failure to specify the exact location of the neoplasm
  • Misclassification of benign tumors as malignant
  • Lack of follow-up documentation post-surgery

Frequently Asked Questions

What is the difference between benign and malignant neoplasms?

Benign neoplasms are non-cancerous growths that do not invade surrounding tissues or metastasize, while malignant neoplasms are cancerous and can spread to other parts of the body.
