Adding a service line: the five questions every payer asks. Ask them before the equipment arrives.

A practice adds a service the way it adds anything else. Someone sees the demand, prices the equipment, trains the staff and books the first patients. The payers come last, and that is where a new service line stalls.

Each payer reads a new service against its own rules. One plan covers a treatment, the next covers it for a single diagnosis, and a third excludes it outright. The questions below are the ones every payer works through, whether or not it says so out loud. Ask them first and the answer is in writing before the money is spent.

1. Is it a benefit on this patient's plan?

Coverage starts in the plan document, before any code or chart note matters. A plan that excludes a service excludes it for every member, however strong the medical case.

Weight management shows how sharply the line falls. The visits and the counseling go to the medical plan, billed against a documented diagnosis. The drug is a separate question. GLP-1 drugs prescribed for weight loss sit on the exclusion list of most employer and Marketplace plans.^A A practice that plans the program as if the drug were covered prices it wrong from the first patient. We read each payer's exclusions for the service first, because a no at this step ends the question for that plan.

2. Which code describes it, and is that code right?

A payer pays a code, not a service. The code has to describe what was done, where on the body, and in what way, and the payer's policy names the codes it accepts for the service.

A code taken from a published guide is only as good as the guide. Botulinum toxin for excessive underarm sweating is billed as chemodenervation of the sweat glands under CPT 64650, and under CPT 64653 for other areas.^B A billing guide written for aesthetics practices listed the wrong code for underarm sweating until its publisher corrected the page. A claim built from the old version would have gone out under the wrong code. Our written answer names the codes each payer's rules point to, and the practice's coder confirms every one against the current code set before a claim goes out.

3. What does the chart have to show?

A covered service, correctly coded, still pays only for the patients who meet the payer's criteria. Those criteria are written down, and the visit note has to carry each one.

Medicare's local coverage determination for oral appliances that treat obstructive sleep apnea is a clear example. It asks for a face-to-face evaluation by the treating practitioner, who may be an MD, DO, nurse practitioner, clinical nurse specialist or physician assistant. It asks for a covered sleep test, with an apnea-hypopnea index of 15 or more, or 5 to 14 with documented symptoms.^C The dentist who makes the appliance cannot supply that diagnosis. A chart without it produces a denial however good the appliance is. We read each payer's criteria for the service and list what the note must show, so the practice builds its templates around them before the first patient.

4. Is the practice enrolled to bill it?

A payer pays a provider it has enrolled, in the role and at the location it has on file. A new service sometimes needs a role the practice has never held.

The same appliance shows it. It is billed to the patient's medical plan under HCPCS E0486, not to the dental plan.^D For Medicare, the dentist who provides it must also be the one who bills it. That means enrolling as a Medicare supplier of durable medical equipment, a DMEPOS supplier, before the first claim. Billing through another supplier's number is not the Medicare path.^C A dental practice that has only ever held dental plan contracts meets this question with nothing on file. We check the enrollment the practice holds against the role each payer requires for the service, and file what is missing as a Payer Enrollment Sprint, tracked to an effective date.

5. Does it need approval before it is done?

Some payers will pay for a service only when they agreed to it before the patient was treated. Prior authorization turns a clinical decision into an administrative one, and it sits on the front desk's calendar, not the provider's.

The load is already heavy before a new service adds to it. In the AMA's physician survey, practices completed about 40 prior authorization requests per physician each week, and physicians and their staff together spent about 13 hours a week on them.^E A service that needs approval from most of its payers adds to that pile with every booking. We list which payers require approval for the service and what each asks to see, so the practice knows the staffing cost before it books the first patient. The weekly load of prior authorization has its own field note.

What we put in writing.

Service Line Made Billable takes one service and works these questions through the payers the practice names. The written answer comes in four parts: which payers cover it, under what codes and documentation, what enrollment or contract is missing, and what the service should pay. The fee is $2,500 for one service. A second service is a second answer.

A payer can rewrite a coverage policy, and a payer decides every claim, so we will not promise that a service will pay. We will say plainly where it will not, and why. Enrollment the answer finds missing is filed as a Payer Enrollment Sprint at its printed prices. Once the service is live, billing and revenue cycle builds each claim to the answer and follows it until it is paid.
