Clinical & Coding Specifications
Clinical Context
A typical patient is an adult male seeking treatment for erectile dysfunction or pulmonary arterial hypertension who receives a prescription for sildenafil citrate, 25 mg, dispensed in an outpatient pharmacy or administered in an ambulatory clinic. The clinical workflow begins with a clinician visit (urology, primary care, or cardiology) documenting symptoms, medication history, and contraindications (notably concurrent nitrate use). The clinician documents the indication and prescribes sildenafil citrate, 25 mg. The medication is provided either as a take-home pharmacy supply or as a clinic-administered dose for an in-office trial in selected cases (for example, evaluation of hemodynamic response in pulmonary hypertension or supervised first-dose observation in patients at higher risk). Billing uses HCPCS Level II code S0090 to report the specific drug product when required by the payer. Clinical documentation should include diagnosis, dose, route, quantity, and any observed response or adverse effects recorded during the encounter.
