Specialty rules are applied to the practice's payers, documentation, and schedule during the engagement.
Where the billing gets difficult
Device data billed without an interpretation
A download from a pump or sensor is not a code by itself. The interpretation and the interaction have to be documented.
Infusion authorizations
Osteoporosis and other infusion drugs are denied when the auth, the dose, or the interval does not match the policy.
High E/M supported only by a medication list
A long list of insulin doses is not medical decision making unless the note shows what was changed and why.
Coding considerations
E/M based on decisions
Medication changes, lab review, and risk are coded from the assessment. Stable refills are not automatically high level.
Device services
Interpretation codes are used only when the practice's note meets the code and a separate entity is not already billing it.
Drug administration
Infusion time and drug units follow the administration record. The drug code and the admin code are both required when both were provided.
Documentation the claim needs
- What changed in the regimen and why
- Interpretation of device data when that service is billed
- Infusion start and stop times
- Authorization number and interval for scheduled drugs
Reimbursement complexity
Endocrinology cash is mostly E/M plus a smaller set of high-dollar drug administrations. The drug claim can dwarf the visit and can be lost to a single authorization error. Continuous glucose and pump work is a documentation trap: patients assume the download is included, and payers expect a defined service. Labs drawn in the office need a decision about whether the practice bills the lab or sends it out. Double billing a reference lab is a compliance problem, not a win.
Proposed approach
01
Separate drug visits from cognitive visits
Infusion days have an auth checklist. Clinic days have an E/M checklist. They are not the same queue.
02
Bill device services from the interpretation
Downloads without a signed interpretation are held.
03
Clarify lab ownership
In-office labs and send-out labs are listed so only the performed component is billed.
Workflow checks
- Regimen-change coding review
- Infusion auth and time capture
- Device interpretation queue
- Lab ownership check
Questions
Do you bill diabetic supplies as DME?
Only if the practice is enrolled to supply them and the engagement includes that work. Most endocrine engagements are professional services, not a supply company.
Can CGM interpretation be added to every diabetes visit?
No. The code has its own requirements. Adding it because a patient wears a sensor is not supported coding.
