Coding Guidelines for G90

G90 is a valid ICD-10-CM diagnosis code meaning 'Disorders of autonomic nervous system'.

Purely Excluded Conditions

These diag codes should never be used at the same time as G90 because these conditions cannot occur together:

  • dysfunction of the autonomic nervous system due to alcohol (G31.2)

Complications & Comorbid Conditions (CC/MCC) Rules for G90

G90 is not a CC or MCC.

DRG Mapping Rules for G90

G90 doesn't map to any MS-DRGs.

About the Turquoise Health MS-DRG Manual Browser

We build tools and machine learning systems that simplify healthcare revenue cycle operations. We were frustrated with the formatting of the MS-DRG rules, so we built our own solution.

MS-DRG rules and ICD-10 CM/PCS codes are automatically parsed from CMS's MS-DRG data files. All content is provided strictly “AS IS” and may contain parsing errors. If you spot an error, please let us know.

We have converted the MS-DRG logic into fully structured, machine-readable data. If you need structured data versions of the MS-DRG manuals, we would love to talk with you.
