Secondary malignant neoplasm of unspecified site. C79.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2018/2019 edition of ICD-10-CM C79.9 became effective on October 1, 2018.
The guidelines are based on the coding and sequencing instructions from the Tabular List and the Alphabetic Index in ICD-10-CM. These guidelines are for medical coders who are assigning diagnosis codes in a hospital, outpatient setting, doctor’s office or some other patient setting.
The majority of metastatic neoplasms to the bone are carcinomas. ICD-10-CM C79.51 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0): 456 Spinal fusion except cervical with spinal curvature, malignancy, infection or extensive fusions with mcc.
When a patient is admitted because of a primary neoplasm with metastasis and treatment is directed toward the secondary site only, the secondary neoplasm is designated as the principal diagnosis even though the primary malignancy is still present.
ICD-10 Code for Secondary malignant neoplasm of unspecified site- C79. 9- Codify by AAPC.
If patient presents for treatment of secondary site ONLY, report the secondary code first, followed by primary malignancy. C79. 9 (Secondary malignant neoplasm of unspecified site) should be assigned when no site is identified for the secondary neoplasm.
Note: There are codes for cancer of C80. 1 Malignant (primary) neoplasm, unspecified and C79. 9 Secondary malignant neoplasm of unspecified site. A diagnosis of metastatic cancer not otherwise specified (NOS) is used most often when diagnostic tests were not completed.
Code C80. 1, Malignant (primary) neoplasm, unspecified, equates to Cancer, unspecified.
If the site of the primary cancer is not documented, the coder will assign a code for the metastasis first, followed by C80. 1 malignant (primary) neoplasm, unspecified. For example, if the patient was being treated for metastatic bone cancer, but the primary malignancy site is not documented, assign C79. 51, C80.

6. When a patient is admitted because of a primary neoplasm with metastasis and treatment is directed toward the secondary site only, the secondary neoplasm is designated as the principal diagnosis even though the primary malignancy is still present.
A malignant neoplasm (NEE-oh-plaz-um) is another term for a cancerous tumor. The term “neoplasm” refers to an abnormal growth of tissue. The term “malignant” means the tumor is cancerous and is likely to spread (metastasize) beyond its point of origin.
Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis.
C80. 1 - Malignant (primary) neoplasm, unspecified. ICD-10-CM.
Secondary malignant neoplasm is a malignant tumor whose cause is the treatment (usually radiation or chemotherapy) which was used for a prior tumor. It must be distinguished from Metastasis from the prior tumor or a relapse from it since a secondary malignant neoplasm is a different tumor. Secondary malignant neoplasm.
Patients diagnosed with bone metastases were identified using a diagnostic code (ICD-10 code for bone metastasis: C795).
A primary cancer is where a cancer starts. Sometimes cancer cells can break away from the primary cancer and settle and grow in another part of the body. This new cancer growth is called secondary cancer. Secondary cancers are also called metastases.
Breast Cancer Scenario: Should be coded as historical (Z85. 3) after the breast cancer has been excised or eradicated, there is no active treatment directed to the breast cancer and there is currently no evidence of disease or recurrence.
Metastatic cancer has the same name as the primary cancer. For example, breast cancer that spreads to the lung is called metastatic breast cancer, not lung cancer. It is treated as stage IV breast cancer, not as lung cancer.
Cancer that begins in the lungs is called primary lung cancer. Cancer that spreads to the lungs from another place in the body is known as secondary lung cancer.
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.
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.
When a primary malignancy has been previously excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy at that site, a code from category Z85, Personal history of malignant neoplasm, should be used to indicate the former site of the malignancy. Any mention of extension, invasion, or metastasis to another site is coded as a secondary malignant neoplasm to that site. The secondary site may be the principal or first-listed with the Z85 code used as a secondary code.
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.
Chapter 2 of the ICD-10-CM contains the codes for most benign and all malignant neoplasms. Certain benign neoplasms , such as prostatic adenomas, may be found in the specific body system chapters. To properly code a neoplasm, it is necessary to determine from the record if the neoplasm is benign, in-situ, malignant, or of uncertain histologic behavior. If malignant, any secondary ( metastatic) sites should also be determined.
Code C80.0, Disseminated malignant neoplasm, unspecified, is for use only in those cases where the patient has advanced metastatic disease and no known primary or secondary sites are specified. It should not be used in place of assigning codes for the primary site and all known secondary sites.
When a pregnant woman has a malignant neoplasm, a code from subcategory O9A.1 -, malignant neoplasm complicating pregnancy, childbirth, and the puerperium, should be sequenced first, followed by the appropriate code from Chapter 2 to indicate the type of neoplasm. Encounter for complication associated with a neoplasm.
There are also codes Z85.6, Personal history of leukemia, and Z85.79, Personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues. If the documentation is unclear as to whether the leukemia has achieved remission, the provider should be queried.
Code C80.1, Malignant ( primary) neoplasm, unspecified, equates to Cancer, unspecified. This code should only be used when no determination can be made as to the primary site of a malignancy. This code should rarely be used in the inpatient setting.
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.
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.
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, ...
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 ). The spread of cancer to the small intestine. This may be from a primary intestinal cancer, or from a cancer at a distant site. The spread of the cancer to the small intestine.
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.
Thyroid cancer metastatic to bone. Clinical Information. Cancer that has spread from the original (primary) tumor to the bone. The spread of a malignant neoplasm from a primary site to the skeletal system. The majority of metastatic neoplasms to the bone are carcinomas.
secondary carcinoid tumors ( C 7B.-) secondary neuroendocrine tumors ( C7B.-) Cancer that has spread from the original (primary) tumor to the bone.
If the documentation states the cancer is a metastatic cancer, but does not state the site of the metastasis, the coder will assign a code for the primary cancer, followed by code C79.9 secondary malignant neoplasm of unspecified site.
If the site of the primary cancer is not documented, the coder will assign a code for the metastasis first, followed by C80.1 malignant (primary) neoplasm, unspecified. For example, if the patient was being treated for metastatic bone cancer, but the primary malignancy site is not documented, assign C79.51, C80.1.
When coding malignant neoplasms, there are several coding guidelines we must follow:#N#To properly code a malign ant neoplasm, the coder must first determine from the documentation if the neoplasm is a primary malignancy or a metastatic (secondary) malignancy stemming from a primary cancer.
When a current cancer is no longer receiving treatment of any kind, it is coded as a history code. For instance, the patient had breast cancer (C50.xx) and underwent a mastectomy, followed by chemoradiation. The provider documents that the patient has no evidence of disease (NED).
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.
