Specialty rules are applied to the practice's payers, documentation, and schedule during the engagement.
Where the billing gets difficult
Regimen changes after authorization
A dose change or a substituted drug can fall outside the approved authorization. The claim then denies at a very high amount.
Administration hierarchy errors
Initial, sequential, and concurrent administration codes follow rules and time. Sequencing them by habit misstates the service.
Professional and facility roles blurred
In a facility, the physician's professional service and the hospital's drug claim are different. Billing both from the practice is a serious error.
Coding considerations
Drug units
Units follow the HCPCS definition and the dose given. Wastage is reported only when the rule and the record support it.
Administration codes
Hydration, therapeutic infusion, and chemotherapy administration are not freely interchangeable. Time and sequence come from the record.
E/M and treatment planning
A visit on an infusion day is billed separately only when the evaluation is distinct from the drug administration.
Documentation the claim needs
- Drug, dose, route, and time
- Authorization that matches the regimen given
- Who purchased the drug
- A distinct evaluation when an E/M is claimed on a treatment day
Reimbursement complexity
Oncology is where a single unit error matters. The proposed control is a regimen checklist before submission, not a promise of collected percentages. Denials for authorization and for administration sequencing should be tracked separately so prevention is specific. Patient responsibility on oral drugs billed through a pharmacy is not the same receivable as a buy-and-bill infusion. Reports that blend them will mislead the practice about its own A/R.
Proposed approach
01
Checklist the regimen
Drug, dose, auth, and purchaser are confirmed before the claim is released.
02
Code administration from the time record
Hierarchy follows the record of what ran, for how long, and in what order.
03
Keep facility claims out of scope
If the site is a hospital department, the engagement states which professional codes remain and stops there.
Workflow checks
- Regimen and auth match
- Administration time coding
- Drug-purchaser flag
- Same-day E/M review
Questions
Do you bill radiation oncology facility services?
Facility radiation billing is not offered. Professional treatment-planning codes can be discussed only when the physician performed them and the note is available.
Can automation code a regimen?
Not unattended. A checklist may flag a mismatch. A person confirms the dose and the authorization before submission.
