The consultation costs nothing. There is no charge for it, no obligation, and nothing to pay or arrange beforehand.
It is a phone call — normally five to ten minutes, longer if it needs to be. Dr. Jimenez asks what happened and what you are feeling, answers what can be answered over the phone, and says whether this is something the practice can help with. Some questions are better answered after an examination, and he will say so rather than guess.
It is not an appointment, an examination, or a diagnosis, and by itself it does not create a physician-patient relationship — the first clause above is the one that governs that. It is the conversation in which both sides work out whether being seen here makes sense for you. Either of you can conclude that it does not, and if this isn’t the right practice for your injury we will say so and, where we can, point you somewhere better.
