Instructional notes

Code first: code the underlying condition first, then this code

condition resulting from (sequela) of inflammatory and toxic polyneuropathies

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 G65.

Excludes1: not coded here, use a different code

All codes under G65

G65 MS-DRGs

As the principal diagnosis, all 3 billable codes under G65 group to MS-DRG 073 or 074 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

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.

Code history
