About coding Polyradiculoneuropathy
The ICD-10-CM code for Polyradiculoneuropathy is G61.0 (Guillain-Barre syndrome).
Within G61 (inflammatory polyneuropathy), G61.0 is specifically for Guillain-Barre syndrome. Related codes cover serum neuropathy (G61.1), other inflammatory polyneuropathies (G61.8) and unspecified (G61.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 094 (Bacterial and Tuberculous Infections of Nervous System with MCC, relative weight 3.4124), DRG 095 (Bacterial and Tuberculous Infections of Nervous System with CC, relative weight 2.3492) and DRG 096 (Bacterial and Tuberculous Infections of Nervous System without CC/MCC, relative weight 2.3213), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
