Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with advanced HIV infection and a CD4 count below 200 cells/mm3 presents to an infectious disease clinic for routine outpatient management. The clinician prescribes prophylaxis against Pneumocystis jiroveci pneumonia due to immunosuppression. The prescription is documented in the electronic health record, counseling about adherence and adverse effects is provided, and the medication is sent to the pharmacy or dispensed from clinic stock. Typical workflow steps include diagnosis confirmation, medication selection (commonly trimethoprim-sulfamethoxazole or alternative), documentation of indication and duration, and communication of the prescription to the patient and payer for billing under G9221 for Pneumocystis jiroveci pneumonia prophylaxis prescribed.
