ICD-10-CM Code D49.3

Neoplasm of unspecified behavior of breast

Version 2020 Billable Code Neoplasm Unspecified Behavior

Valid for Submission

D49.3 is a billable code used to specify a medical diagnosis of neoplasm of unspecified behavior of breast. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D49.3 might also be used to specify conditions or terms like neoplasm of areola of female breast, neoplasm of areola of male breast, neoplasm of axillary tail of female breast, neoplasm of breast, neoplasm of central portion of female breast, neoplasm of ectopic female breast tissue, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: areola ; breast (connective tissue) (glandular tissue) (soft parts) ; breast (connective tissue) (glandular tissue) (soft parts) areola ; breast (connective tissue) (glandular tissue) (soft parts) axillary tail ; breast (connective tissue) (glandular tissue) (soft parts) central portion ; breast (connective tissue) (glandular tissue) (soft parts) inner ; breast (connective tissue) (glandular tissue) (soft parts) lower ; etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D49.3:

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2019 through 09/30/2020.

Table of Neoplasms

The code D49.3 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


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
