Endocrinology Billing Services
Endocrinology billing services for diabetes management, thyroid disorders, hormone replacement, and endocrine procedure billing aligned with payer.
What Endocrinology Billing Has to Capture
Endocrinology is management-heavy, with revenue concentrated in ongoing evaluation rather than procedures. Continuous monitoring, education services and device-related billing are frequently delivered but not captured on the claim.
- Visit levels supported by documented management complexity
- Continuous monitoring services billed where criteria are met
- Education and counselling captured when separately billable
- Chronic care management applied where the patient qualifies
Endocrinology Billing Services Explained
Endocrinology billing centers on chronic disease management for diabetes and thyroid disorders, continuous glucose monitoring billing, and in-office procedure medical coding for thyroid biopsies, bone density testing, and hormone implant procedures. The CGM billing landscape has evolved significantly with CMS adding new codes for professional CGM interpretation and patient-applied CGM supply billing.
Medsure RCS manages endocrinology medical billing for Florida practices with accurate chronic disease E/M coding, CGM professional and personal use billing, and prior authorization management for GLP-1 medications and insulin pump programs. Endocrinology is part of our specialty medical billing program for chronic disease management practices.
How It Works: Step by Step
Chronic Disease E/M Coding
Office visit levels are determined by Medical Decision Making complexity for diabetes, thyroid, and other endocrine conditions per 2024 AMA E/M guidelines.
CGM Service Billing
Professional CGM interpretation (99091 or 99473-99474) and patient-applied CGM supply billing are managed with correct code selection based on the CGM device type and service model.
In-Office Procedure Coding
Thyroid biopsy, bone density scan, testosterone or estrogen implant procedures, and insulin pump management codes are selected with correct approach and complexity documentation.
Chronic Care Management Enrollment
CCM-eligible endocrine patients (diabetes plus one additional chronic condition) are enrolled, documented, and billed monthly under 99490-99491.
Why This Matters for Your Revenue Cycle
Endocrinology-specific E/M coding and CGM billing accuracy drive first-pass acceptance above 95%.
Current CGM billing codes applied based on device type and service model as codes have evolved.
Endocrinology claims are submitted within 48 hours of signed documentation receipt.
All eligible endocrine patients are enrolled in CCM monthly billing where applicable.
Common Mistakes in Endocrinology Billing Services
Wrong CGM Billing Code by Service Type
CGM billing has distinct codes for physician-supplied professional CGM (99091), patient-applied personal CGM interpretation (99473-99474), and CGM supply billing (A9276-A9279). Using the wrong code for the CGM service type results in systematic denial.
Billing Insulin Pump Management Without Documentation
Insulin pump (CSII) management billing requires documentation of the pump parameters reviewed, settings adjusted, and clinical reasoning. Generic documentation without pump-specific detail does not support these codes.
Missing Diabetes Education Separate Code
Diabetes self-management education (DSMT) is a separately covered benefit under Medicare and many commercial plans when provided by a certified diabetes educator. Providing education without billing the DSMT codes results in uncollected education revenue.
Wrong DEXA Code for Site Scanned
DXA bone density scanning uses different codes based on the anatomic site measured: axial skeleton (77080), peripheral (77081), and vertebral fracture assessment (77082). Billing the wrong site code based on incomplete documentation results in payment discrepancy.

Endocrinology Billing Services, Frequently Asked Questions
Professional CGM involves the physician supplying the CGM device to the patient for a period, interpreting the data, and billing 99091 (collection and interpretation of physiologic data). Patient-applied personal CGM involves the patient owning the device, with the physician interpreting downloaded data and billing 99473 for the first 30 days of training or 99474 for ongoing interpretation.
Yes. Thyroid ultrasound performed to evaluate the thyroid is billed with 76536. If an FNA biopsy is performed under ultrasound guidance on the same day, the biopsy code (10005) is billed with the ultrasound guidance code (76942). The diagnostic ultrasound is not billed separately when guidance is included in the procedure.
A high-complexity MDM level for diabetes requires documentation of uncontrolled diabetes affecting multiple organ systems, new or worsening complications, drug therapy requiring intensive monitoring, and a management plan with multiple treatment decisions made at the visit. The documentation must clearly state the diagnoses, data reviewed, and management decisions, not just the history and exam.
Yes. Injectable GLP-1 agonists (semaglutide, tirzepatide, dulaglutide, etc.) are billed using their J-codes or NDC codes depending on the payer. Prior authorization is required from most commercial payers. We manage auth requests with clinical indication documentation and bill the drug and administration codes correctly when administered in-office.
