2021 ICD-10-CM Code D49.3

Neoplasm of unspecified behavior of breast

Version 2021

Valid for Submission

D49.3 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of unspecified behavior of breast. The code D49.3 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 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: Neoplasm, neoplastic areola ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) areola ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) axillary tail ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) central portion ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) inner ; Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) lower ; etc

Unspecified diagnosis codes like D49.3 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.

Code Classification

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 coding notes and 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

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.
