About coding Trapezius paralysis
The ICD-10-CM code for Trapezius paralysis is G52.8 (Disorders of other specified cranial nerves).
Within G52, choose G52.8 (Disorders of other specified cranial nerves) only when documentation doesn't support a more specific option: disorders of olfactory nerve (G52.0), disorders of glossopharyngeal nerve (G52.1), disorders of vagus nerve (G52.2), disorders of hypoglossal nerve (G52.3), disorders of multiple cranial nerves (G52.7) and cranial nerve disorder, unspecified (G52.9).
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.
