About R09.A

R09.A is the ICD-10-CM diagnosis code for foreign body sensation of the circulatory and respiratory system. It belongs to category R09 (other symptoms and signs involving the circulatory and respiratory system), 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 a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

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

To report this condition, pick the subcode that matches the documentation: R09.A0 (unspecified), R09.A1 (nose), R09.A2 (throat) and R09.A9 (site).

It was added in FY2024, effective October 1, 2023.
