About coding brachial plexus disorder
The ICD-10-CM code for brachial plexus disorder is G54.0 (Brachial plexus disorders).
Within G54 (nerve root and plexus disorders), G54.0 is specifically for brachial plexus disorders. Related codes cover lumbosacral plexus disorders (G54.1), cervical root disorders, not elsewhere classified (G54.2), thoracic root disorders, not elsewhere classified (G54.3), lumbosacral root disorders, not elsewhere classified (G54.4), Neuralgic amyotrophy (G54.5), Phantom limb syndrome with pain (G54.6), Phantom limb syndrome without pain (G54.7), other nerve root and plexus disorders (G54.8) and 1 more.
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.
