C47.20 - Malignant neoplasm of peripheral nerves of unspecified lower limb, including hip

Version 2023
ICD-10:C47.20
Short Description:Malig neoplasm of prph nerves of unsp lower limb, inc hip
Long Description:Malignant neoplasm of peripheral nerves of unspecified lower limb, including hip
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Malignant neoplasms of mesothelial and soft tissue (C45-C49)
      • Malignant neoplasm of prph nerves and autonomic nervous sys (C47)

C47.20 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of peripheral nerves of unspecified lower limb, including hip. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference the parent code C47.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic nerve (ganglion) femoral ; Neoplasm, neoplastic nerve (ganglion) obturator ; Neoplasm, neoplastic nerve (ganglion) olfactory ; Neoplasm, neoplastic nerve (ganglion) peripheral NEC ankle ; Neoplasm, neoplastic nerve (ganglion) peripheral NEC calf ; Neoplasm, neoplastic nerve (ganglion) peripheral NEC extremity lower ; Neoplasm, neoplastic nerve (ganglion) peripheral NEC foot ; etc

Unspecified diagnosis codes like C47.20 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.

Approximate Synonyms

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

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The parent code C47.2 of the current diagnosis code is referenced 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.

Cancer

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.

Peripheral Nerve Disorders

Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.

There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.

Symptoms often start gradually, and then get worse. They include :

Treatment aims to treat any underlying problem, reduce pain and control symptoms.
