Is ICD-10-CM code G61 billable?

No, G61 (Inflammatory polyneuropathy) is a non-billable ICD-10-CM code. It must be coded to a more specific subcategory before it can be used for reimbursement.

What chapter does ICD-10-CM code G61 belong to?

G61 belongs to Chapter 6 of the ICD-10-CM tabular list: G00–G99 (Diseases of the Nervous System).

G61Not billable, use a more specific code below

Inflammatory polyneuropathy

In Polyneuropathies and other disorders of the peripheral nervous system (G60-G65), chapter 6: Diseases of the Nervous System

6 billable codes under G61: 2 are a CC; 2 map to HCC 193 (Chronic Inflammatory Demyelinating Polyneuritis and Multifocal Motor Neuropathy).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

Instructional notes

Also applies, from Polyneuropathies and other disorders of the peripheral nervous system (G60-G65)

These notes sit on G60-G65 and apply to every code under it, including G61.

Excludes1: not coded here, use a different code

neuralgia NOS (M79.2)

DRG 073 Cranial and Peripheral Nerve Disorders with MCC (5 of 6 codes)
DRG 074 Cranial and Peripheral Nerve Disorders without MCC (5 of 6 codes)
DRG 094 Bacterial and Tuberculous Infections of Nervous System with MCC (1 of 6 codes)
DRG 095 Bacterial and Tuberculous Infections of Nervous System with CC (1 of 6 codes)
DRG 096 Bacterial and Tuberculous Infections of Nervous System without CC/MCC (1 of 6 codes)

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Peripheral Nerve Disorders

Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs. Peripheral nerves carry messages from your brain that control your movement, breathing, heartbeat, digestion, and more. They also carry messages from your body to your brain, so you can feel things, such as pain, heat, and cold.
