    Clinical & Coding Specifications

    Clinical Context

    A 78-year-old patient with advanced heart failure (NYHA class III), chronic kidney disease stage 4, and type 2 diabetes is enrolled in a complex chronic care management program. The patient is homebound, has recent weight gain and increasing dyspnea, and is at high risk for hospitalization due to fluid overload and renal decompensation. A physician directs a clinical staff member (registered nurse or licensed practical nurse) to provide structured management and care plan services. In the first month, the clinical staff perform an initial 30 minutes of care plan management (documented elsewhere). During a subsequent calendar month the clinical staff provide an additional 60 minutes of documented interactive care management time (beyond the first 30 minutes). Activities include medication reconciliation, symptom assessment, coordination with a cardiologist and nephrologist, patient education on diuretic titration, documentation of updated problem list and goals in the electronic health record, and communication of changes to the supervising physician. Time is cumulative and documented in 30-minute increments per calendar month; use of 99427 is appropriate for each additional 30 minutes of clinical staff time beyond the first 30 minutes in the month.
