Non-specific codes like D24 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for benign neoplasm of breast:

  • Use D24.1 for Benign neoplasm of right breast - BILLABLE CODE

  • Use D24.2 for Benign neoplasm of left breast - BILLABLE CODE

  • Use D24.9 for Benign neoplasm of unspecified breast - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Includes

  • benign mammary dysplasia N60
  • benign neoplasm of skin of breast D22.5 D23.5
  • fibrocystic disease of breast N60

Patient Education


Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form a tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Breast Diseases

What are breast diseases?

Breast diseases include various conditions and changes in your breast. Most women experience breast changes at some time. Your age, hormone levels, and medicines you take may cause lumps, bumps, and discharges of fluids that are not breast milk.

Although many women fear cancer, most breast changes are benign, meaning they are not cancer. These breast changes are known as benign breast disease. See your health care provider if you have a breast lump, pain, discharge, or skin irritation. Minor and serious breast problems often have similar symptoms and may need treatment.

Common breast changes and conditions can include:

  • Fibrocystic breast changes can include lumpiness, thickening, and swelling, often just before your period. Your breasts may feel painful, swollen, or tender.
  • Cysts are fluid-filled lumps that may be tender.
  • Fibroadenomas are solid, round, rubbery lumps that easily move when pushed, occurring most in younger women.
  • Intraductal papillomas are wart-like benign tumors that grow in the milk duct of the breast.
  • Blocked milk ducts.
  • Milk production when you're not breastfeeding.

What are the symptoms of breast disease?

Symptoms depend on the type of breast disease. Benign breast diseases may not have any symptoms, or they could include:

  • A lump or firm feeling in your breast or under your arm
  • A change in the size or shape of your breast
  • Nipple discharge
  • Skin changes such as itching, redness or darkening, dimples, scaling, or puckering on your breast or nipple
  • Painful, swollen, or tender breasts

See your provider if you're noticing any of these symptoms or other unusual changes. Some symptoms may be warning signs or symptoms of breast cancer.

How are breast diseases diagnosed?

Some breast changes may be felt or seen. You may notice a change in your breast, or your provider may notice it during a clinical breast exam. Other breast changes may only be found during a screening mammogram or other imaging tests such as an MRI or ultrasound. Your provider may also recommend a breast biopsy to check a suspicious change in your breast.

What are the treatments for breast disease?

Some benign breast changes may increase your risk of breast cancer in the future and may need treatment now. Treatment depends on the type of breast disease that you have. Some breast changes may go away without treatment, while others may require monitoring, biopsy, or surgery.
