2023 ICD-10-CM Diagnosis Code D48.6
2023 ICD-10-CM Diagnosis Code D48.6
Neoplasm of uncertain behavior of breast
2016 2017 2018 2019 2020 2021 2022 2023 Non-Billable/Non-Specific Code
- D48.6 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
- The 2023 edition of ICD-10-CM D48.6 became effective on October 1, 2022.
- This is the American ICD-10-CM version of D48.6 - other international versions of ICD-10 D48.6 may differ.
Applicable To- Neoplasm of uncertain behavior of connective tissue of breast
- Cystosarcoma phyllodes
Type 1 ExcludesType 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as D48.6. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

D48.6:
- C00-D49
2023 ICD-10-CM Range C00-D49
NeoplasmsNote- Functional activity
- All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
- Morphology [Histology]
- Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
- Primary malignant neoplasms overlapping site boundaries
- A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
- Malignant neoplasm of ectopic tissue
- Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
- D37-D48
2023 ICD-10-CM Range D37-D48
Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromesNote- Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
Type 1 Excludes- neoplasms of unspecified behavior (D49.-)
- D48
ICD-10-CM Diagnosis Code D48
Neoplasm of uncertain behavior of other and unspecified sites

Type 1 Excludes- neurofibromatosis (nonmalignant) (Q85.0-)
- A benign, borderline, or malignant fibroepithelial neoplasm arising from the breast and rarely the prostate gland. It may recur following resection. The recurrence rates are higher for borderline and malignant phyllodes tumors. In borderline and malignant phyllodes tumors metastases to distant anatomic sites can occur. The incidence of metastases is higher in malignant phyllodes tumors.
- A type of connective tissue neoplasm typically arising from intralobular stroma of the breast. It is characterized by the rapid enlargement of an asymmetric firm mobile mass. Histologically, its leaf-like stromal clefts are lined by epithelial cells. Rare phyllodes tumor of the prostate is also known.
- A type of tumor found in breast or prostate tissue. It is often large and bulky and grows quickly. It may be benign (not cancer) or malignant (cancer) and may spread to other parts of the body.
