Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Disorders of breast
      (N60-N65)
      • Unspecified lump in breast
        (N63)

N63 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of unspecified lump in breast. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The code is commonly used in ob/gyn medical specialties to specify clinical concepts such as lump in breast and other disorders of the breast.

Unspecified diagnosis codes like N63 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to Unspecified lump in breast

Non-specific codes like N63 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 unspecified lump in breast:

  • Use N63.0 for Unspecified lump in unspecified breast - BILLABLE CODE

  • N63.1 for Unspecified lump in the right breast - NON-BILLABLE CODE

  • Use N63.10 for Unspecified lump in the right breast, unspecified quadrant - BILLABLE CODE

  • Use N63.11 for Unspecified lump in the right breast, upper outer quadrant - BILLABLE CODE

  • Use N63.12 for Unspecified lump in the right breast, upper inner quadrant - BILLABLE CODE

  • Use N63.13 for Unspecified lump in the right breast, lower outer quadrant - BILLABLE CODE

  • Use N63.14 for Unspecified lump in the right breast, lower inner quadrant - BILLABLE CODE

  • Use N63.15 for Unspecified lump in the right breast, overlapping quadrants - BILLABLE CODE

  • N63.2 for Unspecified lump in the left breast - NON-BILLABLE CODE

  • Use N63.20 for Unspecified lump in the left breast, unspecified quadrant - BILLABLE CODE

  • Use N63.21 for Unspecified lump in the left breast, upper outer quadrant - BILLABLE CODE

  • Use N63.22 for Unspecified lump in the left breast, upper inner quadrant - BILLABLE CODE

  • Use N63.23 for Unspecified lump in the left breast, lower outer quadrant - BILLABLE CODE

  • Use N63.24 for Unspecified lump in the left breast, lower inner quadrant - BILLABLE CODE

  • Use N63.25 for Unspecified lump in the left breast, overlapping quadrants - BILLABLE CODE

  • N63.3 for Unspecified lump in axillary tail - NON-BILLABLE CODE

  • Use N63.31 for Unspecified lump in axillary tail of the right breast - BILLABLE CODE

  • Use N63.32 for Unspecified lump in axillary tail of the left breast - BILLABLE CODE

  • N63.4 for Unspecified lump in breast, subareolar - NON-BILLABLE CODE

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Patient Education


Breast Diseases

Most women experience breast changes at some time. Your age, hormone levels, and medicines you take may cause lumps, bumps, and discharges (fluids that are not breast milk).

If you have a breast lump, pain, discharge or skin irritation, see your health care provider. Minor and serious breast problems have similar symptoms. Although many women fear cancer, most breast problems are not cancer.

Some common breast changes are:

  • Fibrocystic breast changes - lumpiness, thickening and swelling, often just before a woman's period
  • Cysts - fluid-filled lumps
  • Fibroadenomas - solid, round, rubbery lumps that move easily when pushed, occurring most in younger women
  • Intraductal papillomas - growths similar to warts near the nipple
  • Blocked milk ducts
  • Milk production when a woman is not breastfeeding

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
