Clinical Context
A typical patient is an adult with a chronic inflammatory condition such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, hidradenitis suppurativa, or Crohn disease who requires subcutaneous biologic therapy with adalimumab. The patient presents to an outpatient infusion clinic, specialty pharmacy clinic, or a physician office for administration counseling, medication dispensing verification, and observation for adverse reaction after self-injection training or clinic-administered injection. The clinical workflow includes medication order verification, confirmation of diagnosis and prior authorization status, review of allergies and infection risk (including screening for active infections and tuberculosis where indicated), documentation of lot number and expiration, preparation of the dose (calculated in milligrams), administration of the subcutaneous injection, monitoring for 15–30 minutes for immediate hypersensitivity, and documentation of the service and medication details in the medical record and the billing system using the HCPCS code J0139 billed per milligram of adalimumab supplied.
