About coding hypoventilation
The ICD-10-CM code for hypoventilation is R06.89 (Other abnormalities of breathing). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R06.89.
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.
