About coding Stridor
The ICD-10-CM code for Stridor is R06.1 (Stridor). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R06.1.
Within R06 (abnormalities of breathing), R06.1 is specifically for Stridor. Related codes cover dyspnea (R06.0), Wheezing (R06.2), periodic breathing (R06.3), Hyperventilation (R06.4), mouth breathing (R06.5), Hiccough (R06.6), Sneezing (R06.7), other abnormalities of breathing (R06.8) and 1 more.
Don't report R06.1 together with the conditions in its Excludes1 note: congenital laryngeal stridor (P28.89) and laryngismus (stridulus) (J38.5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
