Clinical & Coding Specifications
Clinical Context
A child or adult with a known diagnosis of asthma presents to a primary care clinic, pediatric clinic, or pulmonology practice for routine follow-up or an acute visit. During the visit the clinician identifies that the patient, a household member, or another caregiver uses tobacco or the patient is exposed to secondhand smoke. The provider documents the tobacco exposure and delivers counseling about smoking cessation medication options (nicotine replacement therapy, varenicline, bupropion) to the patient or to the family member who smokes. Counseling includes assessment of readiness to quit, brief medication information, potential side effects, and referral resources. The interaction is documented in the medical record with the asthma diagnosis, the presence of tobacco use or passive smoke exposure, the content of the discussion about medication for cessation, and any follow-up plan or referrals. Typical sites of service include outpatient primary care clinics, pediatric clinics, pulmonology clinics, and community health centers. Service type: counseling and preventive counseling documented as part of office visit for patients with asthma. Typical patient scenario: a 10-year-old with persistent asthma brought by a parent who smokes; the clinician confirms household smoking, discusses nicotine replacement options and prescriptions for the parent, documents the counseling and plans follow-up to reduce environmental tobacco exposure to improve asthma control.
