About coding Orthopnea
The ICD-10-CM code for Orthopnea is R06.01 (Orthopnea).
Within R06.0 (dyspnea), R06.01 is specifically for Orthopnea. Related codes cover unspecified (R06.00), Shortness of breath (R06.02), acute respiratory distress (R06.03) and other forms of dyspnea (R06.09).
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.
