Typical Clinical Scenarios

An adult patient with severe, diffuse cutaneous T-cell lymphoma hospitalized for systemic symptoms and rapid progression despite outpatient therapies; inpatient phototherapy is initiated as part of systemic extracorporeal light-ray treatment to reduce tumor burden and control widespread skin lesions when close monitoring is required. Typical codes: 6A600ZZ, 6A601ZZ
A pediatric patient admitted after erythroderma from drug reaction with unstable hemodynamics and extensive skin involvement; controlled extracorporeal phototherapy is used in the inpatient setting to rapidly decrease inflammatory skin activity and limit further systemic complications while other supportive measures continue. Typical codes: 6A600ZZ
A patient previously treated as an outpatient for chronic plaque psoriasis who develops superimposed infection and hospital readmission for management; once infection is controlled, inpatient phototherapy is provided to treat persistent, extensive plaques unresponsive to topical therapy and to expedite recovery before discharge. Typical codes: 6A601ZZ
