What good radiology billing execution looks like.

The operating discipline we install on every radiology billing engagement.

  1. Professional / technical component (26 / TC) disciplineRadiology billing requires precise 26 (professional read) vs TC (technical equipment + staff) split per encounter. Radiology practices and imaging centers need clean component billing.
  2. Autonomous coding for radiology reportsRadiology is the most-mature autonomous coding specialty: structured reports + standardized terminology drive 85-95 percent straight-through coding rates at mature implementations.
  3. Prior authorization for advanced imagingMRI, CT, PET, and nuclear medicine require PA from most commercial payers, often through radiology benefit managers (AIM, eviCore). Imaging centers need PA automation tuned for RBM workflows.
  4. AUC + CDS complianceAppropriate Use Criteria and Clinical Decision Support requirements (Medicare PAMA) require specific HCPCS modifier and G-code reporting. Non-compliance triggers payment denials.
  5. Interventional radiology procedure codingIR procedures carry complex code stacks (radiologic supervision + interpretation, embolization, biopsy, drainage) with bundling rules. Specialty coders required.
  6. Multi-procedure payment reduction (MPPR) awarenessMPPR reduces payment on second and subsequent radiology procedures on the same date of service. Radiology billing needs MPPR-aware revenue forecasting.

Professional, technical and global split map

The same study, four settings, four different things you may bill.

A diagnostic imaging study is rarely one billable thing. Most imaging codes split into a professional component, reported with modifier 26, and a technical component, reported with modifier TC. Which piece belongs to the practice is not a coding preference. It is decided by who supplied the equipment, the staff and the supplies, and by where the study actually ran. The exhibit below is drawn from the coding and enrollment rules that govern the split, not from sample data and not from a client.

The split that decides the claim

Diagnostic studies split into a professional component and a technical component. Every code on the Medicare Physician Fee Schedule carries a PC/TC indicator that states whether it splits at all, and site of service decides which piece you may bill.

The IDTF rulebook

An independent diagnostic testing facility is enrolled in its own right and has to meet performance standards covering supervision, personnel qualifications and equipment. Those standards sit at 42 CFR 410.33 and they govern the technical component the facility bills.

The second study pays less

The multiple procedure payment reduction applies to advanced imaging performed on the same patient on the same day, and it reaches the technical component separately from the professional one. A practice that forecasts imaging revenue on full fee schedule rates forecasts money it will not receive.

Revenue leakage taxonomy

The five places imaging revenue actually leaks.

Radiology denials are not random. They cluster into five drivers, and every one of them is settled by a decision made before the study is performed. This is the taxonomy we work against on every radiology and imaging engagement.

Leakage driverHow the dollars go missingThe pre-bill control we installFixable pre-bill
The component splitModifier 26, modifier TC or globalThe practice reads studies inside a hospital and bills globally out of habit, or owns the scanner in its own suite and bills only the professional component. The claim passes every edit and pays. It is simply the wrong amount, and the version that overpays is the one that comes back on audit with interest attached.Site of service written into the charge rule per modality, so the 26, TC or global decision is made by where the study ran and who supplied the equipment, not by whichever rule the billing desk learned first.Yes
Place of service accuracyThe code that should carry the splitThe place of service code on the professional claim disagrees with where the study was actually performed. Payers price the professional component differently by setting, so a wrong place of service either underpays the read or overpays it in a way that is recoverable later.Place of service driven from the scheduling record and the performing site rather than typed at charge entry, with a pre-bill check that the place of service and the modifier tell the same story.Yes
Advanced imaging authorizationMRI, CT, PET and nuclearThe study is scheduled and performed before the payer has answered, so it is billed at risk. Or the authorization is obtained for a different code, a different modality or a different site than the one that ran, which produces a denial on a claim that had a valid authorization number on it.Authorization opened when the order is received rather than the day before the appointment, tracked against the decision timeframes finalised at 89 FR 8758, and reconciled against the code and site actually performed before the claim is released.Partly
Contrast and supply billingWhat travels with the technical sideContrast, radiopharmaceuticals and the supplies consumed by the study belong to whoever owns the technical component. A practice that reads studies performed elsewhere sometimes bills for contrast it never bought, and a practice that runs its own suite sometimes never bills for the contrast it did buy.Supply and contrast lines tied to the technical component decision rather than entered independently, so the supply follows the equipment, with units and wastage captured from the modality record.Yes
Reading site versus performing siteMulti-site groups and teleradiologyA group with several sites, leased equipment or an off-site reading arrangement applies one billing rule across all of it. Half the volume is then over-billed and the other half under-billed, and because the two errors partly offset in the aggregate, nothing in the monthly report looks wrong.A per-site rule set that fixes the technical component to the performing site and the professional component to the reading physician, checked at the line rather than assumed at the group level.Yes

The table describes ASP-RCM's operating taxonomy and the controls we install. It does not assert denial frequencies. Denial mix is measured per practice during the free 30-day audit against your own last 90 days of claim data. The authorization row reflects the decision timeframes finalised in the CMS Interoperability and Prior Authorization final rule at 89 FR 8758.

The authorization gate

Advanced imaging: who is holding the clock.

MRI, CT, PET and nuclear medicine are the studies payers guard hardest, and they are guarded through utilization management rather than through coding edits. From January 1, 2026 impacted payers must decide a standard request within 7 calendar days and an expedited request within 72 hours, under the CMS Interoperability and Prior Authorization final rule at 89 FR 8758. That clock only starts when somebody starts it. Our full treatment of the authorization stage is in the prior authorization command center whitepaper, and the parallel component discipline for diagnostic studies is covered on the cardiology billing services page.

Decision timeframes shown are those finalised in the CMS Interoperability and Prior Authorization final rule, 89 FR 8758, February 8, 2024, effective for impacted payers from January 1, 2026. Commercial plans outside that rule set their own timeframes under their own utilization management policies.

Radiology and imaging billing FAQ

Questions imaging practice owners actually ask.

When do you bill modifier 26, modifier TC, or the global service on an imaging study?

It is decided by who owns the equipment and who performed the interpretation. If the practice supplies the equipment, the staff and the supplies, it bills the technical component. If the physician only reads the study, it bills the professional component with modifier 26. Only when the practice does both does it bill globally. Each code on the Medicare Physician Fee Schedule carries a PC/TC indicator that states whether the code can split at all, and site of service is what should drive the decision. A practice that reads studies inside a hospital and bills globally out of habit is billing for equipment it does not own.

How does place of service change what an imaging practice may bill?

Place of service is the field that should carry the split onto the claim. When the study runs in the practice's own suite, the practice supplied the scanner, the technologist and the contrast, so both components were earned and the global service is correct. When the study runs in a hospital department, the facility bills the technical side on its own claim and the reading physician is left with the professional component only. The failure mode is a place of service code typed at charge entry that disagrees with where the study actually ran, because at that point the modifier and the place of service tell two different stories about the same encounter and only one of them can be true.

What are the prior authorization timelines for advanced imaging?

From January 1, 2026 impacted payers must decide standard prior authorization requests within 7 calendar days and expedited requests within 72 hours. The requirement comes from the CMS Interoperability and Prior Authorization final rule published at 89 FR 8758 on February 8, 2024, and it reaches Medicare Advantage organisations, state Medicaid and CHIP programmes and their managed care plans, and issuers of qualified health plans on the federally facilitated exchanges. For an imaging practice the volume lands on MRI, CT, PET and nuclear medicine. Commercial plans outside that rule set their own timeframes under their own utilization management policies, which is why an imaging practice is usually running several different clocks at once.

Who bills for the contrast and the supplies used in a study?

Whoever owns the technical component. The technical side of a diagnostic study is the equipment, the room, the staff who ran it and the supplies consumed doing so, and contrast and radiopharmaceuticals are part of that. A practice that reads studies performed somewhere else has no supply to bill and should never have a contrast line on its claim. A practice that runs its own imaging suite bought the contrast and should be billing it with accurate units and wastage taken from the modality record. The common leak is the second one, because the supply line is entered separately from the procedure line and nothing forces the two to agree.

What is an independent diagnostic testing facility and why does it change the billing?

An IDTF is enrolled with Medicare in its own right rather than as part of a physician practice or a hospital, and it has to meet the performance standards at 42 CFR 410.33, which cover physician supervision of the tests, the qualifications of the non-physician personnel who perform them, and the equipment itself. Because the facility is its own enrolled entity, it bills the technical component and the interpreting physician bills the professional component separately. That also raises the stakes on compliance: a supervision or standards gap is not a single denied claim, it is a question about the enrollment and therefore about every claim billed under it.
