Endocrinology billing for practices and groups: diabetes visits and continuous glucose monitoring, diabetes education, thyroid ultrasound and biopsies, bone density testing, and injectable drugs such as denosumab billed by the unit, worked inside the software you already use.
Endocrinology billing gets visits, device readings, biopsies and injections paid, each under its own rules. Glucose monitoring is billed to the right code for who owns the device, education is billed under the program that runs it, procedures are coded with the imaging they include, and payments are posted and checked against what each plan owes.

Endocrinology mixes long-term visits with device data, procedures and drugs. A diabetes patient may have a visit, a continuous glucose monitor reading to interpret, diabetes education and a supply order in the same month, and each piece has its own code and coverage rule. Thyroid and bone care add biopsies, ultrasound and injectable drugs billed by the milligram.
Who owns the device, and what the note shows, decide the claim. That is why we check device ownership, interpretation dates, units and documentation on every endocrinology claim before it goes out.
Endocrinology practices bill visits, device data, procedures and injections for the same patients across the year. Each fails in its own way. Here is what goes wrong in each, and what we do.
Pays forDiabetes visits, the start of personal and professional glucose monitoring, and the monthly interpretation of the data.

What we do
Glucose monitoring is billed with three codes. 95249 covers starting a patient on a personal monitor they own: sensor placement, hook-up, calibration, training and a printout, reported once while the patient has that equipment. 95250 covers a professional monitor the practice owns and lends to the patient, with at least 72 hours of data. 95251 is the analysis and report, billed no more than once a month and also needing at least 72 hours of data.
The monitor itself and its sensors are usually billed by a supplier, not the practice. For Medicare, the supplier needs a treating practitioner’s order and records showing the patient uses insulin or has a history of problematic low blood sugar, with an in-person or telehealth visit in the six months before the order and every six months after.
What we do: before a CGM claim goes out, we check who owns the device, the dates and hours of data reviewed and the last interpretation billed. For Medicare patients we confirm the visit and the documentation the supplier will need, so the device order is not held up.
Diabetes, thyroid and bone care each bring their own codes. These are the ones behind most endocrinology claims, with what payers check on each.
| Code | What it covers | What payers look for |
|---|---|---|
| 99202 to 99215 | Office visits (E/M) | The level matches the decision making or time documented; modifier 25 with a same-day procedure only when the visit is separate. |
| 952499525095251 | Continuous glucose monitoring: patient-owned start, practice-owned study, interpretation | Device ownership, at least 72 hours of data, and 95251 once a month. |
| G0108G0109 | Diabetes self-management training, individual and group | A recognized program; up to 10 hours in the first year and 2 hours a year after. |
| 9780297803 | Medical nutrition therapy | Provided by a registered dietitian, for diabetes or kidney disease under Medicare. |
| 76536 | Thyroid and neck ultrasound | 26 or TC when the study and the reading are split. |
| 1000510006 | Fine needle aspiration with ultrasound guidance, first and each additional lesion | Guidance included; not billed with 76942. |
| 77080 | Bone density (DXA), hip and spine | Medicare once every 24 months unless more frequent testing is medically necessary. |
| J0897 | Denosumab, per 1 mg | 60 units for a 60 mg dose, with JZ or JW and authorization where required. |
| J3489 | Zoledronic acid, per 1 mg | Units from the dose given, and the diagnosis that supports it. |

It is not for every practice. If you are a hospital-employed group whose billing the hospital handles, you do not need us. And if your in-house team keeps denials low and receivables current, keep them, and consider a periodic billing audit instead.
We look at your clean-claim rate, your denials by payer and reason, glucose monitoring codes, education and drug units, biopsy and DXA coding, and your aging receivables, and tell you what we find, whether or not you go further with us.
We get access to your practice management system and clearinghouse, load each payer's authorization and bundling rules and your fee schedules, list patients on glucose monitoring and open drug authorizations, and agree how escalations work. Most practices are live within one to two weeks.
Visits, device readings and injections are coded and claims submitted within 24 hours. Rejections are corrected the same day, remittances posted as they arrive, device ownership, data hours and drug units checked, and denials worked to their cause, all inside your system.
A report you can read in ten minutes: what was billed and collected by payer, site and service line, what was denied and why, authorizations pending, and what is aging.
You do not change systems to work with Summit Billing Solutions. We work in the practice management and EHR systems below, and through the clearinghouse you already use. If your EHR is not shown, ask; the list grows as we onboard practices.

Endocrinology revenue arrives in small pieces: visits, monthly device readings, education sessions and injections. A fee that is a share of collections means we are paid for chasing every one of those pieces, not just the large claims.
Summit Billing Solutions charges between 3% and 9% of monthly collections. Your rate reflects how many patients use glucose monitors, how much you bill in injectable drugs, your visit volume and the state of the receivables, which the free account review shows us.

We bill for more than 40 specialties, for practices in all 50 states, from Salem, New Hampshire. Each one has its own codes, modifiers and payer rules.
A free account review looks at your clean-claim rate, your denials by payer and reason, glucose monitoring codes, biopsies, bone density and drug units, and your aging receivables, and tells you what we would change. No cost, no obligation, and no pressure to continue. What the review covers, step by step, is on the free account review page.
