Sjogren syndrome with peripheral nervous system involvement

This code identifies Sjögren syndrome, a chronic autoimmune disorder characterized by dry eyes and mouth, when it is complicated by peripheral nervous system (PNS) involvement. This includes conditions such as peripheral neuropathy, mononeuritis multiplex, or ganglionopathy directly attributable to the underlying Sjögren syndrome.

Use this code when documentation clearly indicates a diagnosis of Sjögren syndrome and a co-occurring peripheral neuropathy or other PNS manifestation that the provider explicitly links to the Sjögren syndrome. This applies to patients experiencing symptoms like numbness, tingling, weakness, or pain in the extremities, where diagnostic workup confirms a peripheral nervous system disorder in the context of established Sjögren syndrome.

• Ensure the medical record explicitly states the causal link between Sjögren syndrome and the peripheral nervous system involvement.
• Do not use this code for PNS involvement due to other causes, even in a patient with Sjögren syndrome.
• Code any specific type of peripheral neuropathy (e.g., G60.x, G62.x) as an additional diagnosis, if specified and not inherent to the Sjögren's PNS involvement.
