About coding periodic breathing
The ICD-10-CM code for periodic breathing is R06.3 (Periodic breathing). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R06.3.
Within R06 (abnormalities of breathing), R06.3 is specifically for periodic breathing. Related codes cover dyspnea (R06.0), Stridor (R06.1), Wheezing (R06.2), Hyperventilation (R06.4), mouth breathing (R06.5), Hiccough (R06.6), Sneezing (R06.7), other abnormalities of breathing (R06.8) and 1 more.
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
