This thread worries me.
As an example, someone presents with low back pain. You will perform a structural examination and mark the appropriate somatic dysfunction in the objective section of the note. Maybe the cause is really a herniated disc, muscle strain, whatever - somatic dysfunction is now on your differential in the assessment portion of the note. During the encounter the patient asked, "My friend had this thing called, OMM - do you think that would be beneficial for me today?" You performed lumbar soft tissue and subsequently indicate that you performed this technique in the plan section of the note.
