About coding bronchial cough
The ICD-10-CM code for bronchial cough is R05.8 (Other specified cough).
Within R05, choose R05.8 (Other specified cough) only when documentation doesn't support a more specific option: acute cough (R05.1), subacute cough (R05.2), chronic cough (R05.3), syncope (R05.4) and unspecified (R05.9).
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 204 (Respiratory Signs and Symptoms, relative weight 0.821), in MDC 04 (Diseases and Disorders of the Respiratory 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.
