Individual professional and general liability for radiation therapy - external beam, IGRT and SBRT delivery, brachytherapy support, and treatment setup in oncology centers and hospital departments.
Radiation therapy has a feature that sets it apart from every other imaging or technical role in healthcare: the treatment is delivered in fractions, the same way, day after day. A setup error is therefore not a single event. It repeats at every session until somebody notices - which means the harm compounds while the mistake stays invisible.
Homewood places individual cover for radiation therapists across oncology centers, hospital radiation departments, and multi-site health systems, with the extensions that matter as delivery techniques get more precise: SBRT, IGRT, and brachytherapy support.

INDUSTRY PRICING DATA — 2026
What Radiation Therapists Pay for Liability Insurance
Current 2026 market data at $1M/$3M limits. An employed therapist delivering external beam treatment runs $400–$1,200 a year for professional liability, rising to $900–$2,500 where the role includes stereotactic delivery or brachytherapy support, and $1,200–$3,000 for contract therapists working across multiple systems. General liability adds $250–$700.

The error does not happen once - it happens every day until somebody catches it
A misread film is a single wrong image. A radiation therapy setup error is something else: a course of treatment is delivered in twenty, thirty, sometimes forty fractions, and a systematic error in immobilization, isocentre placement, or plan transcription is reproduced faithfully at every one of them. By the time it surfaces, the patient has received a cumulative dose to the wrong volume, and no part of it can be taken back. That single structural fact explains most of how the role is underwritten. It is why carriers care so much about verification imaging frequency and whether the therapist is empowered to stop a session and escalate. It is why the plan-transcription check - comparing what is on the treatment console against what the oncologist prescribed - is worth more to an underwriter than any amount of general experience. And it is why the therapist's willingness to halt treatment matters: in a workflow designed for daily repetition, the person at the console is the last opportunity to notice that the repetition is wrong.

Bar heights use a square-root scale. Radiation therapists price above most imaging roles and below prescribing clinicians, reflecting a narrow but very high-severity exposure. For comparison, our radiologic technologist page prices diagnostic imaging at $500–$2,000, and facility-level cancer treatment cover is set out on our cancer treatment centers page.
Which techniques move the premium most
Stereotactic delivery: SBRT and SRS
40 – 80%; high dose per fraction
Brachytherapy support
35 – 70%; source handling exposure
Pediatric radiation therapy
30 – 60%; lifetime dose consequences
Plan transcription and dose entry
25 – 50% without a second check
Immobilization and setup
20 – 40%; repeated across fractions
IGRT verification imaging
15 – 30%; added imaging dose
Bar widths are scaled to the top of each band, as increases on the base professional liability premium. Note the pattern: the two highest are the techniques that deliver the most dose in the fewest sessions, where a single error has no subsequent fraction in which to be noticed.
What Drives a Radiation Therapist's Premium
↑Pushes premium higher
Stereotactic delivery, SBRT and SRS
Brachytherapy support and source handling
Pediatric and adolescent caseloads
Responsibility for plan transcription or dose entry
Contract or agency work across multiple systems
Prior dose incidents or a board complaint
Practicing in a high-litigation state
↓Keeps premium lower
Current ARRT (T) registration and state licensure
A documented second check on plan transcription
Verification imaging at defined intervals, with records
Written authority to halt a session and escalate
Immobilization device checks recorded per fraction
Timeout and patient identification protocols
Equipment QA and calibration records
Written authority to stop a session is the item that costs nothing and is almost never in a submission. Underwriters read it as evidence that the last check in the chain actually functions.
Individual cover for a radiation therapist is built from professional liability for the delivery work, with general liability where you carry premises exposure. Malpractice and liability insurance provides essential protection against these risks:
Professional Liability (Malpractice) Insurance
Your core protection against treatment claims:
Errors in radiation delivery - overexposure, underdosing, or beam misalignment.
Harm to surrounding tissue, treatment site complications, and failure to escalate concerns to the supervising oncologist.
Incorrect immobilization, setup positioning errors, or shielding failure - the errors that repeat across a fractionated course.
Patient misidentification and treatment delivered from the wrong plan.
Coverage extended to IGRT, SBRT, and brachytherapy support.
Liability for electronic treatment records, consent documentation, and charting responsibilities.
Optional protection for therapists involved in clinical research, student supervision, or multi-modality planning teams.
Limits up to $1,000,000 per claim / $3,000,000 aggregate, with tail, prior acts, and portability across health systems.
General Liability Insurance
Third-party bodily injury from slips, falls, and accidents in treatment and waiting areas.
Injuries during patient transfers or positioning onto the treatment couch.
Property damage involving equipment, immobilization devices, or patient belongings.
Personal and advertising injury for non-medical reputation claims.
Standard limits of $1,000,000 per occurrence / $3,000,000 aggregate, with umbrella available.
Recommended Add-Ons
License protection and board defense - a dose incident triggers a regulatory review as well as any civil claim, and the two run separately.
Tail and prior acts coverage - radiation injury can present long after treatment ends, so a gap between policies is a real exposure rather than a theoretical one.
Portability across health systems - therapists frequently cover sister sites, and cover should follow the person.
Clinical research extension - where you deliver treatment on trial protocols.
Cyber liability - treatment records and imaging archives hold identifiers as well as clinical data.
Radiation therapy is a narrow, high-severity exposure: claim frequency is low, but consequences are serious and irreversible. Premiums reflect technique mix more than volume. These are planning ranges:
Despite their expertise and the highly controlled nature of the work, radiation therapists are exposed in several specific areas:
Incorrect dosage administration - the most significant risk. An overdose causes severe injury or worsens side effects; an underdose renders the treatment ineffective against the cancer it was meant to treat.
Misalignment or misapplication of radiation - beams that damage healthy tissue and organs adjacent to the treatment volume.
Failure to monitor and respond to side effects - therapists see patients daily and are best placed to notice deterioration, which makes failure to report it consequential.
Inadequate patient communication about the procedure, side effects, and post-treatment care.
Technical and equipment failures - malfunction or calibration error producing incorrect dose or targeting.
Breach of confidentiality - oncology records are among the most sensitive a provider holds.
Inadequate safety measures - protecting patients and staff from accidental exposure is a strict-protocol obligation.
Failure to follow the treatment plan - deviating without proper authorization renders treatment ineffective or harmful.
Malpractice insurance provides financial protection against these claims, covering legal defense costs, settlements, and judgments. Homewood works with a number of different carriers to bring you the most suitable coverage at the best price.
Higher-Risk Techniques and Their Impact on Your Premiums
Conventional fractionated external beam therapy is written comfortably across the market. These six areas account for most of the variation between one therapist's premium and another's.
Technique / Responsibility
Description & Risks
Insurance Impact
Stereotactic Delivery: SBRT and SRS
Very high dose delivered in few fractions to a small volume. There is little or no subsequent session in which an error might be noticed and corrected.
A 40–80% increase; carriers look for image guidance at every fraction and a documented second check.
Brachytherapy Support
Assisting with sealed source placement, where handling, positioning, and source accounting all carry exposure alongside the clinical risk.
A 35–70% increase; source inventory and survey records are examined.
Pediatric Radiation Therapy
Dose delivered to a developing patient, where consequences extend across a lifetime and secondary malignancy risk is material.
A 30–60% increase, driven by severity rather than frequency.
Plan Transcription and Dose Entry
Where the therapist enters or confirms prescription data at the console rather than only delivering an approved plan.
A 25–50% increase without a documented independent second check.
Immobilization and Setup
Positioning and immobilization errors, which reproduce identically across every fraction of a course until identified.
A 20–40% increase; setup verification records are the mitigating evidence.
IGRT Verification Imaging
Frequent verification imaging adds cumulative imaging dose on top of the therapeutic dose, and mis-registration steers the beam.
A 15–30% increase; protocols defining imaging frequency reduce it.
Some carriers underwrite radiation therapists with strict attention to technique mix, and a generic allied-health policy may not name the ones that matter. At Homewood, we help you:
Match with carriers that accept your technique mix, including stereotactic delivery and brachytherapy support.
Confirm that SBRT, IGRT, and brachytherapy are named on the policy rather than assumed into it.
Strengthen submissions by presenting verification imaging protocols, second-check procedures, and QA records.
Structure tail and prior acts deliberately, given that radiation injury can present long after treatment ends.
Arrange portability where you cover sister sites within a health system.
Negotiate favorable limits, deductibles, and endorsements at competitive rates.
