Code Description

ICD-10 D17.23 is a billable code used to indicate a diagnosis of benign lipomatous neoplasm of skin and subcutaneous tissue of right leg.

Key Diagnostic Point:

A benign lipomatous neoplasm, commonly referred to as a lipoma, is a soft tissue tumor composed of adipose (fat) tissue. These neoplasms are typically slow-growing and painless, often presenting as a soft, movable lump under the skin. In the case of D17.23, the neoplasm is specifically located in the skin and subcutaneous tissue of the right leg. Lipomas are generally considered benign and do not have malignant potential; however, they can cause discomfort or cosmetic concerns depending on their size and location. Diagnosis is usually made through physical examination, and imaging studies such as ultrasound or MRI may be utilized to assess the tumor's characteristics. Treatment is often not necessary unless the lipoma is symptomatic or the patient requests removal for aesthetic reasons. Regular surveillance may be recommended to monitor for any changes in size or symptoms, although malignant transformation is exceedingly rare. Coders should ensure accurate documentation of the location and characteristics of the lipoma to support the use of this specific code.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of benign neoplasms, improving the accuracy of data collection and reimbursement processes. D17.23 provides specificity that was not available in ICD-9.

Frequently Asked Questions

What is the typical treatment for a lipoma?

Most lipomas do not require treatment unless they are symptomatic or the patient requests removal for cosmetic reasons. Surgical excision is the most common treatment.

Can a lipoma become malignant?

Lipomas are benign tumors and have a very low risk of malignant transformation. However, any changes in size or symptoms should be evaluated by a healthcare provider.
