About coding Bulbospinal paralysis
The ICD-10-CM code for Bulbospinal paralysis is G70.00 (Myasthenia gravis without (acute) exacerbation). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G70.00.
Within G70.0, choose G70.00 (without (acute) exacerbation) only when documentation doesn't support a more specific option: with (acute) exacerbation (G70.01).
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 056 (Degenerative Nervous System Disorders with MCC, relative weight 2.2655) and DRG 057 (Degenerative Nervous System Disorders without MCC, relative weight 1.2838), 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.
