I am a little confused between Acute uncomplicated that is low risk of functional impairment vs Acute illness with systemic symptoms that has a high risk of functional impairment w/o treatment. For example, patient presents with 2 months of neck pain. Patient was diagnosed with Cervical Spondylosis, no treatment from us but being referred to pain management. Is this considered just acute illness or would this be considered acute with systemic symptoms. Spondylosis can cause functional impairment but since we are not doing further treatment but referring him out.
