Hyperhidrosis and other services that look cosmetic and are covered. The diagnosis decides, not the room it is treated in.

A payer does not care where a treatment happens. It cares what the treatment is for. The same injection can be a cosmetic purchase in one chart and a covered medical service in the next, and the difference sits in the diagnosis and the note. Practices that run medical care beside aesthetic work often bill all of it as cash, because nothing in the building was set up to pursue insurance.^A Some of that work was payable the whole time.

Hyperhidrosis: a sweat-gland procedure, not a wrinkle treatment.

Botulinum toxin for excessive sweating is chemodenervation of the eccrine sweat glands. The code follows the site treated. The underarms bill under CPT 64650. Other areas, such as the hands or feet, bill under CPT 64653.^B

The guide we cite for those two codes corrected its own hyperhidrosis mapping, and it now warns readers off the code that circulated before. Older copies of that advice are still around. A claim built on the old code goes to the payer as the wrong procedure, and no note can repair that.

Whether a plan covers the procedure, and what it wants in the chart first, is that plan's call, written in that plan's own policy. We read that policy for each payer the practice bills, before the first treatment, so the patient hears the answer before the syringe comes out.

Chronic migraine: same drug, a fixed protocol.

Botulinum toxin is labelled by the FDA to prevent chronic migraine. It is given in a fixed pattern of injection sites, the PREEMPT protocol, and a payer pays for it once the record shows the headache frequency and migraine features the label requires.^C The chart carries the claim. If the note does not show what the label asks for, the payer sees a cosmetic injection.

This procedure has its own chemodenervation code. Our research could not confirm the digits from a source we trust, so we do not print it here, and we would not bill it until we had read it in the current code set and the payer's policy.

Vascular birthmarks and scars: the policy decides.

Laser treatment of a port-wine stain is billed as destruction of a vascular lesion of the skin when it is medical, not cosmetic. Payers write their own tests. Aetna's clinical policy bulletin 0559, for one, lists laser treatment of port-wine stains and other hemangiomas on the face and neck among the uses it covers when its selection criteria are met.^D

Laser work on a scar has no code of its own. Each plan measures the request against its scar-revision policy, and Cigna publishes one as a coverage position with written criteria.^E We build the request from that plan's criteria, point by point, so the reviewer finds each one in the record.

Where the visit pays and the product does not.

Several services split in two. The evaluation is medical care. The treatment that follows may not be. Hair loss is the plainest case: the dermatology visit and the lab workup go to the medical plan, while platelet-rich plasma for pattern hair loss is treated as cosmetic or experimental by nearly every commercial plan. The narrow exceptions are hair loss from alopecia areata or from chemotherapy, and only with strong documentation.^F

Infusions split the same way. A hydration infusion is billable when the note documents a medical need, such as dehydration, a deficiency, or hydration around a procedure. A wellness drip is not, and it stays a cash service.^G Medical weight management follows the pattern too, and we cover it in the note on adding a service line.

What stays cash, and the tax question beside it.

A treatment done to change how someone looks is cosmetic, and no claim changes that. We will not bill it to insurance. Some practices ask about a letter of medical necessity instead, which can make a purchase eligible for a health savings or flexible spending account. That letter has to attest that the service treats, mitigates or prevents a diagnosed condition.^H It is a close cousin of the test a payer applies, set by the tax code's definition of medical care instead of by a plan. If the diagnosis is not in the chart, neither route is open.

What we do with a menu like this.

We start from the practice's service menu and the payers it bills. For each service that could be medical, the written answer names the payers that cover it, the code and diagnosis each one expects, what the note must show, and who has to be enrolled to bill it. In an aesthetics practice that is usually the medical director, and the practice itself. That answer is the Service Line Made Billable, at a fixed $2,500 for one service.

Then we enroll the providers who have to be on file, and our billing service builds each claim with the code, the diagnosis and the note in agreement, and follows it until it is paid. State law governs who may own and bill for medical care in an aesthetics setting. That part belongs with the practice's attorney.
