About R06.3
R06.3 is the ICD-10-CM diagnosis code for periodic breathing. It belongs to category R06 (abnormalities of breathing), block R00-R09 (symptoms and signs involving the circulatory and respiratory systems) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 786.04 (Cheyne-Stokes respiration).
