About coding Breathlessness
The ICD-10-CM code for Breathlessness is R06.81 (Apnea, not elsewhere classified).
Within R06.8 (other abnormalities of breathing), R06.81 is specifically for apnea, not elsewhere classified. Related codes cover tachypnea, not elsewhere classified (R06.82), Snoring (R06.83) and other abnormalities of breathing (R06.89).
Don't report R06.81 together with the conditions in its Excludes1 note: apnea (of) newborn (P28.4-), sleep apnea (G47.3-) and sleep apnea of newborn (primary) (P28.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for R06.81)
