About coding respiratory arrest

The ICD-10-CM code for respiratory arrest is R09.2 (Respiratory arrest). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R09.2.

Within R09 (other symptoms and signs involving the circulatory and respiratory system), R09.2 is specifically for respiratory arrest. Related codes cover asphyxia and hypoxemia (R09.0), pleurisy (R09.1), abnormal sputum (R09.3), other specified symptoms and signs involving the circulatory and respiratory systems (R09.8) and foreign body sensation of the circulatory and respiratory system (R09.A).

Don't report R09.2 together with the conditions in its Excludes1 note: cardiac arrest (I46.-), respiratory arrest of newborn (P28.81), respiratory distress of newborn (P22.0), respiratory failure (J96.-) and 3 more.

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
