Valid for Submission
C77.8 is a billable diagnosis code used to specify a medical diagnosis of secondary and unspecified malignant neoplasm of lymph nodes of multiple regions. The code C77.8 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C77.8 might also be used to specify conditions or terms like metastasis to multiple lymph nodes, n1b: metastasis in bilateral, midline, or contralateral cervical or mediastinal lymph node, n1b: metastasis in multiple regional lymph nodes or secondary malignant neoplasm of lymph nodes of multiple sites.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: lymph, lymphatic channel NEC gland (secondary) multiple sites in categories C77.0 - C77.5 .
Unspecified diagnosis codes like C77.8 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Metastasis to multiple lymph nodes
- N1b: Metastasis in bilateral, midline, or contralateral cervical or mediastinal lymph node
- N1b: Metastasis in multiple regional lymph nodes
- Secondary malignant neoplasm of lymph nodes of multiple sites

|822||LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITHOUT CC/MCC||17||1.2516|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Table of Neoplasms
The code C77.8 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
Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.
