What makes endocrinology billing services different
Endocrinology billing services span three kinds of work that bill under different rules: office visits and counseling for diabetes and hormone conditions, procedures such as thyroid ultrasound and fine needle aspiration, and devices — continuous glucose monitors and insulin pumps — that cross into durable medical equipment billing. A practice can do everything right on the visit coding and still lose revenue on the device side if the DME rules are not followed. Fastora's certified billing and coding professionals handle these claims for endocrinology practices as part of our wider medical billing services.
Diabetes care also brings education and nutrition services with their own codes, coverage limits and provider requirements. Diabetes self-management training and medical nutrition therapy are covered benefits under specific conditions — but only when the program, the referral and the clinician credentials meet the payer's rules.
Diabetes education and nutrition billing
Diabetes self-management training is reported with G0108 for individual sessions and G0109 for group sessions, and medical nutrition therapy uses 97802 through 97804. Both require a referral, and DSMT must come from an accredited program — claims from non-accredited programs deny regardless of how good the education was.
Coverage limits are strict: initial DSMT hours, follow-up hours and MNT hours each have annual caps that vary by payer, and the hours are tracked across providers. We verify accreditation, referral status and remaining hours before these services are scheduled, not after they deny.
CGM, insulin pumps and the DME crossover
| Code | Descriptor (summary) | Billing note |
|---|---|---|
| G0108 | Diabetes self-management training, individual | Accredited program and referral required |
| G0109 | Diabetes self-management training, group | Annual hour caps apply |
| 97802 | Medical nutrition therapy, initial assessment | Physician referral required |
| 97803 | Medical nutrition therapy, re-assessment | Hour caps tracked across providers |
| 95249 | Personal CGM startup and training | Device initiation visit |
| 95250 | Professional CGM placement and interpretation | Office-owned sensor, minimum wear time |
| 76536 | Ultrasound, soft tissues of head and neck | Thyroid and parathyroid imaging |
| 77080 | Bone density study, axial | DXA frequency limits by payer |
Continuous glucose monitors sit at the boundary between the medical benefit and the DME benefit. Professional CGM — the office-owned sensor placed and interpreted in clinic — bills to the medical side, while personal CGM systems the patient takes home are DME billed with supply codes to the DME contractor. Sending a personal CGM claim to the wrong contractor guarantees a denial.
Insulin pumps are DME, which means detailed written orders, face-to-face documentation and the KX modifier rules apply just as they do for any equipment supplier. Practices that dispense pumps need the DME-side documentation discipline, not just the visit-side habits. Our medical coding team reviews device claims against both sets of rules before submission.
Thyroid, bone health and infusion billing
Thyroid nodule workups combine ultrasound imaging, fine needle aspiration and sometimes molecular testing of the sample. The ultrasound, the aspiration and the pathology interpretation are separate services that may be performed by different clinicians on different dates, and each needs its own documentation.
Osteoporosis care adds bone density studies with payer-specific frequency limits and injectable or infused therapies that need prior authorization. The drug, the administration and the diagnosis supporting medical necessity must agree, or the drug claim and the administration claim deny for different reasons.
Eligibility across medical and DME benefits
We run eligibility and benefits checks before visits and device orders, confirming diabetes supply benefits, DME coverage for pumps and personal CGM, and whether infusions or advanced imaging need authorization. Device coverage often sits with a separate DME vendor or a carved-out benefit manager, which the front desk needs to know before promising the patient a timeline.
Common endocrinology billing denials and how we prevent them
| Denial | Typical cause | Prevention step |
|---|---|---|
| DSMT denied | Program not accredited or referral missing | Accreditation and referral verified before scheduling |
| CGM to wrong contractor | Personal CGM billed to Part B instead of the DME MAC | Benefit type confirmed before the claim is built |
| Pump claim denied | Missing detailed order or KX modifier | DME documentation checklist completed at dispense |
| Infusion auth missing | Drug approved but administration site not covered | Auth confirmed for drug, code and site of care |
| DXA frequency | Bone density study billed sooner than the payer allows | Prior study dates checked against payer limits |
Every claim passes our Advanced Pre-Submission Claim Review before submission. Denials that still occur are worked by our denial management team, which corrects and resubmits or appeals with the record, and open balances are followed up by payer and age.
Credentialing for endocrinologists
Endocrinologists, diabetes educators and dietitians each need enrollment with the plans they bill, and new clinicians need to be linked to the group before their claims pay in network. DSMT programs carry their own accreditation and enrollment requirements beyond the individual clinician.
Our credentialing and enrollment service tracks each file through a nine-stage process, from document collection and NPI and CAQH setup to payer applications, follow-ups and final approval.
How Fastora supports endocrinology billing
Fastora works inside your existing EHR/PM system under the user access you grant, with no software to install and no hidden setup fees. You get a dedicated account contact, transparent dashboards, monthly performance reporting and a monthly review call.
Fees are quoted after a free assessment, and you can read how our pricing models work beforehand. To see how your current claims hold up, start with a free billing assessment.
Endocrinology billing: chronic care and device-driven services
Endocrinology medical billing blends chronic-care management with procedure work: diabetes education and pump training, thyroid biopsies and ultrasounds, bone density scans and the CGM programs that need ongoing supply billing. Our coding keeps the chronic-care codes distinct from the procedure codes, tracks prior authorization for the high-cost services and follows up on the medical-necessity denials that hit diabetes technology claims. The practice sees one clean A/R report instead of three disconnected workflows. Related services: medical billing services page, medical coding service, prior authorization service.
