About coding acute motor neuropathy

The ICD-10-CM code for acute motor neuropathy is G62.81 (Critical illness polyneuropathy).

Within G62.8 (other specified polyneuropathies), G62.81 is specifically for critical illness polyneuropathy. Related codes cover Radiation-induced polyneuropathy (G62.82) and other specified polyneuropathies (G62.89).

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 073 (Cranial and Peripheral Nerve Disorders with MCC, relative weight 1.5779) and DRG 074 (Cranial and Peripheral Nerve Disorders without MCC, relative weight 1.0173), 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.
