Endocrinology billing services from Medical Billing Services Group (MBSG) cover the full revenue cycle for diabetes, thyroid, pituitary, adrenal, and bone-health care — from evaluation and management visits through diabetes self-management training, continuous glucose monitor claims, and chronic care management. We handle the coding rules that make endocrine billing complex, so your practice captures the full value of longitudinal chronic-disease care.

Practice/setting fit
Our endocrinology billing services fit private endocrinology groups, diabetes centers, hospital-affiliated endocrine clinics, and multispecialty practices with heavy endocrine volume. Endocrinology billing is distinctive because so much of the revenue is longitudinal: the same diabetic patient generates office visits, lab interpretation, diabetes training, device claims, and care-management services across the year, each with its own coverage rules, frequency limits, and documentation standards. A missed training benefit or an unbilled care-management month is revenue that never comes back.
We manage the full revenue cycle for these settings: benefits verification and prior authorization for devices and high-cost therapies, coding that respects bundling edits between visits and procedures, daily claim submission, payment posting with contractual adjustments, and denial follow-up that goes back to the clinical note. Our coding team checks endocrine claims against published CMS coverage rules before submission, and our broader specialty billing programs cover your other service lines.
Documentation and coding risks
Endocrinology’s biggest billing risk is the gap between what was furnished and what the coverage rules allow. Diabetes training, devices, and bone-density studies each carry statutory or regulatory frequency limits — bill outside them and the claim is denied as non-covered, regardless of medical need.
Diabetes self-management training has strict hour and setting rules
Medicare covers outpatient diabetes self-management training (DSMT) under specific statutory conditions: up to 10 hours of initial training furnished within a continuous 12-month period — generally one hour of individual training plus nine hours in a group setting of 2 to 20 individuals — followed by up to 2 hours of follow-up training per calendar year. Training is reported in 30-minute increments with G0108 (individual) and G0109 (group), and time may not be rounded. Claims fail when hours exceed the benefit, when group-size rules are violated, or when the ordering and documentation requirements are not met. We track each beneficiary’s DSMT hours against the benefit so claims stay inside coverage.

Device and supply claims follow DME rules, not office rules
Continuous glucose monitors, insulin pumps, and related supplies are generally billed under durable medical equipment rules with their own coverage criteria, supplier standards, and documentation requirements — not as incidentals to the office visit. Common failure points include missing detailed written orders, insufficient documentation of medical necessity in the treating physician’s records, and refill timing that violates the payer’s utilization rules. Because DME claims process through different payer systems than professional claims, they need separate tracking and follow-up. We manage both streams and reconcile them against the patient’s record.

Chronic care management is billable — if the time is documented
Chronic care management (CCM) pays for the non-face-to-face work of managing patients with multiple chronic conditions — exactly the diabetic, hypertensive, hyperlipidemic population endocrinologists manage. But CCM requires documented clinical staff time, a comprehensive care plan, 24/7 access, and patient consent, and the time thresholds must actually be met and recorded. Practices that do the work but cannot produce the time log lose the revenue; practices that bill without the documentation invite takebacks. We verify CCM documentation against the coverage requirements before billing and track consent and care-plan status per patient.

Payer and authorization checks
Endocrine practices face heavy prior-authorization volume: GLP-1 therapies, continuous glucose monitors, insulin pumps, bone-density studies, and thyroid procedures all commonly require authorization with payer-specific clinical criteria. We verify benefits and secure authorizations before the service where required, confirm the diagnosis coding supports medical necessity under each payer’s policy, and track authorization expirations against scheduled services. Our eligibility and prior authorization team handles this volume so your clinical staff does not have to.
Workflow and reporting
Endocrine practices need reporting that reflects longitudinal care. We provide visit-level and patient-level reporting (E&M distribution, DSMT hours used versus benefit remaining, device claim status, CCM months billed), denial reporting by cause (frequency-limit denials, authorization failures, bundling edits, documentation), and payer-level payment tracking. Reports arrive on a set schedule with every metric defined, so trends are comparable month to month. Payment posting includes contractual adjustments per payer fee schedule, and denial management follows a documented path from correction to appeal.
Onboarding and pricing factors
Onboarding an endocrinology practice starts with a review of your current E&M coding distribution, DSMT hour tracking, device claim workflows, and CCM documentation against Medicare’s coverage rules — the four areas where endocrine revenue most often leaks. We then map your service mix to the correct codes and coverage rules, confirm we can work inside your existing EHR and practice-management systems with compatibility confirmed during onboarding, and set up daily claim submission. We do not publish flat rates: pricing is quoted and scoped in your written proposal after we review your visit volume, payer mix, device billing, and systems. Data is handled under our HIPAA safeguards and business associate agreement. No client outcomes are cited until verified and permissioned.
FAQs and dated sources
What does Medicare cover for diabetes self-management training?
Medicare covers up to 10 hours of initial DSMT within a continuous 12-month period (generally one individual hour plus nine group hours) and up to 2 hours of follow-up training per calendar year afterward, reported in 30-minute increments with G0108 (individual) and G0109 (group). The training must be ordered, furnished by an accredited program, and documented to coverage standards. Source: 42 CFR §410.141 — last reviewed 2026-10-08.
Why do CGM and insulin pump claims get denied?
The most common causes are missing or incomplete detailed written orders, treating-physician documentation that does not establish the coverage criteria, refill requests outside the payer’s allowed timing, and billing supplies as professional services instead of through DME channels. We check orders, documentation, and refill timing before submission.
Can our practice bill chronic care management for diabetic patients?
CCM is billable for patients with two or more chronic conditions expected to last at least 12 months when the practice provides the required care-plan, access, and documented clinical staff time elements and obtains patient consent. The time thresholds must be met and recorded — undocumented time cannot be billed. We audit CCM documentation before claims go out.
How often does Medicare cover bone mass measurements?
Medicare statute provides for bone mass measurement (e.g., DEXA) once every two years for qualified beneficiaries, with specific coded exceptions for medical need. Billing more frequently without meeting an exception produces non-covered denials. We track measurement intervals per patient against the coverage rule.
Do you handle prior authorizations for GLP-1 and other endocrine therapies?
Yes. We verify benefits, submit prior authorization requests with the clinical documentation each payer requires, track authorization status and expirations, and manage denials and appeals when coverage is refused. Authorization rules are payer-specific, so we confirm each payer’s criteria during onboarding.
Do you work with our existing EHR?
Yes — we work inside your existing systems, and compatibility is confirmed during onboarding before we take over claim submission.
