Specimen collection
About 89220: Aerosol-induced sputum collection
Reports aerosol-induced collection of sputum when a diagnostic specimen is needed, such as when a patient cannot produce an adequate sample by coughing.
This service obtains a sputum specimen through aerosol induction, commonly using nebulized saline to help a patient produce respiratory secretions for diagnostic testing. It is used when a spontaneously expectorated sample is not available or adequate. Clinical staff, such as respiratory therapists or nurses, may perform the collection in an outpatient setting under the responsible practitioner’s direction. The collected specimen may be sent for microbiology or cytopathology testing; those laboratory analyses are distinct from obtaining the sample.
Report 89220 for the induced collection, not for testing or interpreting the specimen. Documentation should identify the aerosol-induced technique and the specimen obtained. CMS classifies this as a technical-component-only service, with interpretation covered by a separate code; do not report modifier 26 on 89220 to represent interpretation. The separate test code depends on the analysis performed, such as culture or cytopathology.

89220 billing questions
When should 89220 be selected instead of a routine sputum collection?
Use it when aerosol induction is used to obtain sputum for diagnostic testing, typically because the patient cannot produce an adequate specimen by coughing.
Does 89220 include sputum culture or cytology?
No. It represents obtaining the induced specimen. The laboratory reports the applicable analysis, such as bacterial culture or cytopathology, under its own code.
Can modifier 26 be appended to 89220?
No. CMS identifies 89220 as technical-component-only, and a separate code covers interpretation.
What documentation supports reporting 89220?
Document that aerosol induction was performed to obtain sputum and identify the specimen collected. A note that only records a spontaneously expectorated sample does not establish this technique.
Is 89220 the same as collecting a sputum sample during bronchoscopy?
No. This code represents aerosol-induced sputum collection. A specimen obtained as part of a bronchoscopic procedure is associated with that procedure instead.
