356.9ICD-9-CM Coding Peripheral neuropathy that is not further specified as being caused by an underlying condition is assigned to code 356.9.
Hereditary and idiopathic neuropathy, unspecified G60. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM G60. 9 became effective on October 1, 2021.
Some forms of neuropathy involve damage to only one nerve (called mononeuropathy). Neuropathy affecting two or more nerves in different areas is called multiple mononeuropathy or mononeuropathy multiplex. More often, many or most of the nerves are affected (called polyneuropathy).
Polyneuropathy is when multiple peripheral nerves become damaged, which is also commonly called peripheral neuropathy. Peripheral nerves are the nerves outside of the brain and spinal cord. They relay information between the central nervous system (CNS), and all other parts of the body.
356.9 is a legacy non-billable code used to specify a medical diagnosis of unspecified hereditary and idiopathic peripheral neuropathy. This code was replaced on September 30, 2015 by its ICD-10 equivalent.

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.
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an approximate match to ICD-9 code 356.9:
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an exact match to ICD-9 code 356:
Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.
