Endocrinology practices routinely leave revenue in CGM analysis, chronic and principal care management, and DSMT/MNT services most practices know exist but rarely bill — on top of thyroid procedures and E&M documentation that has to match the complexity actually managed.
Common Billing Challenges
These are the six billing failure points we see most often in endocrinology practices — and the ones our team resolves systematically from day one.
Every time you pull and review CGM data at a visit, that's a billable service — as long as you document the review and time spent. It's one of the most frequently missed codes in endocrinology.
Principal Care Management requires 30+ minutes of clinical staff time per month working on care management outside face-to-face visits. Every minute, every month has to be documented to bill it.
Therapeutic, Preventive, or Other Interventions add-on codes (99484, 99491) apply when a physician directly provides care management services. Many endocrinologists qualify but never bill them.
Billing 95251 for CGM analysis and also counting that same review as MDM data to justify a higher-complexity E&M code on the same visit is a compliance error, not a coding shortcut.
Ultrasound guidance billing requires documentation that guidance was actually used during the biopsy — the guidance code is an add-on and should accompany the biopsy code, never stand alone.
Up to 10 hours of DSMT plus 3 hours of MNT annually go unbilled at many practices because referral, delivery, and patient-response documentation isn't being tracked.
Key Procedure Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue — and the most denials — in endocrinology.
| CPT Code | Description | Common Issue |
|---|---|---|
| 99490 Series | Chronic Care Management | Requires non-face-to-face time tracked monthly |
| 99424–99427 | Principal Care Management | 30+ min/month clinical staff time on one complex condition |
| 95251 | Professional CGM analysis | Frequently underbilled; can't double-count as E&M data |
| 99484 / 99491 | TPOT add-on codes | Physician-delivered care management, often left unbilled |
| 76536 / 10005–10006 | Thyroid ultrasound / FNA biopsy | Guidance code must accompany biopsy, documented as used |
| 78012–78018 | Thyroid scan and uptake studies | Modifier -26 if reading only, not performing the scan |
