About coding multiplex mononeuropathy
The ICD-10-CM code for multiplex mononeuropathy is G58.7 (Mononeuritis multiplex).
Within G58 (other mononeuropathies), G58.7 is specifically for mononeuritis multiplex. Related codes cover intercostal neuropathy (G58.0), other specified mononeuropathies (G58.8) and mononeuropathy, unspecified (G58.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
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.
