About coding breathing irregular
The ICD-10-CM code for breathing irregular is R06.89 (Other abnormalities of breathing).
Within R06.8, choose R06.89 (Other abnormalities of breathing) only when documentation doesn't support a more specific option: apnea, not elsewhere classified (R06.81), tachypnea, not elsewhere classified (R06.82) and Snoring (R06.83).
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.
