Houston teleradiology coverage for trauma service area Q

Teleradiology in Houston is bought against an unusual acuity map, and that map, not the licence, is what should shape your contract. Texas designates the nine-county Houston region as Trauma Service Area Q. One service area out of 22 statewide holds 3 of the state's 20 Level I comprehensive trauma facilities and 11 of its 39 comprehensive stroke facilities, with another 28 designated trauma facilities sitting below Level I, while the licence that permits a radiologist to sign a Houston report stays an ordinary full Texas licence, identical to the one covering Lubbock.

This page is for the imaging director, hospital administrator, or imaging-centre owner running coverage inside that service area. The licensure rules are set out in full on our teleradiology licensing in Texas page and are not repeated here. What follows is what the Houston designation pattern does to a coverage plan. Last verified August 2026.

Why does a Houston facility need a different coverage plan from the rest of Texas?

It does not need a different licence. It needs a different study mix assumption. The Houston service area concentrates high-acuity designations more heavily than any Texas region except the Dallas-Fort Worth area, and it pairs that concentration with a wide base of small facilities that stabilise and transfer. Your overnight worklist inherits both halves.

What Trauma Service Area Q contains

Texas publishes its designations, so this is checkable before any vendor conversation starts. The Department of State Health Services designated trauma facility list tags every facility with its trauma service area, and TSA-Q covers Austin, Colorado, Fort Bend, Harris, Matagorda, Montgomery, Walker, Waller, and Wharton counties on the DSHS trauma service area map.

Designation	Facilities in TSA-Q	Texas total	What it implies for imaging
Level I trauma (comprehensive)	3	20	Receiving end of regional transfers, heavy cross-sectional volume
Level II trauma (major)	4	26	Full trauma admission capability, suburban and exurban siting
Level III trauma (advanced)	9	60	Stabilise, image, decide, transfer
Level IV trauma (basic)	15	196	Thin after-hours radiology, highest transfer rate
Comprehensive stroke (Level I)	11	39	Head CT and CTA on a clock, overnight and weekend

Read the first two rows and the last three rows as different businesses. They buy coverage for different reasons.

The base of the Houston pyramid is where the coverage gap lives

Twenty-four of the 31 designated trauma facilities in the Houston service area sit at Level III or Level IV, and those are the sites where an after-hours interpretation gap does the most damage. A Level IV facility exists to stabilise and move a patient, which makes almost every study it performs a disposition study. The emergency physician holding an unread abdominal CT at 2 a.m. has three options, and an interpretation changes which one they pick. In a nine-county region with three Level I centres, a transfer decision is not abstract: it commits an ambulance crew, a receiving bed, and often a helicopter, and it does that whether the study eventually justified the move or not. A final signed report arriving inside the STAT tier lets the physician make that call while the decision is still open. The same logic runs in reverse at the top of the pyramid, where a Level I facility receiving transfers repeats imaging and inherits volume it did not schedule. Both ends of the designation ladder are buying the same thing: a subspecialist who is awake, mid-shift, and licensed in Texas. What differs is how often they need one and at what hour. That is the honest reason a Houston facility should compare coverage models carefully instead of accepting whatever arrangement its region has always used, and it is why overnight nighthawk radiology coverage and daytime overflow radiology reads tend to get bought together here.

Eleven comprehensive stroke facilities put neuro on your night list

The Texas designated stroke facility list places 11 of the state's 39 comprehensive facilities in TSA-Q, more than a quarter of the state's comprehensive stroke capacity inside one service area. Around them sit the primary and support level facilities that see the same patients first.

Head CT and CTA route to a neuroradiologist, assigned by study type before interpretation begins. The panel covers neuro, MSK, body, cardiac, breast, pediatric, chest, emergency, oncologic, and nuclear imaging, and our guide to subspecialty radiology reads by study type shows how each study is routed.

Which studies should stay in Houston and which should move to a remote subspecialist?

Send the interpretation, keep the procedure. That single line resolves most of the question for a facility in this service area, and the designation level mostly decides how the split falls out in practice.

A Level IV or Level III site sends the overnight and weekend cross-sectional load, because that is the window where the reading capacity is thinnest and the clinical clock is shortest. A Level II site tends to send the subspecialty tail: the pediatric study, the cardiac MRI, the nuclear medicine case that arrives four times a month and cannot justify a dedicated hire. A Level I centre usually sends surge and backlog, since its own staff is sized for a normal week and the transfers arriving from the rest of TSA-Q do not respect a normal week.

Everything requiring hands on the patient stays where the patient is. Fluoroscopy supervision, biopsy, drain placement, and any interventional work belong to a physician in the building, and no coverage contract of any kind changes that.

Turnaround tiers a TSA-Q facility can hold a vendor to

Two tiers, one clock, measured from last-image arrival to radiologist signature. The measurement method matters more than the tier, because a vendor that starts its clock at study assignment is measuring a different thing.

Priority	Tier	Typical Houston use
Stroke protocol	Under 30 minutes	Stroke protocol head CT and CTA head and neck, routed ahead of every other STAT read
STAT	Under 4 hours (2h or 1h on request)	Trauma pan-scan, pulmonary embolism, acute abdomen
Routine	24 to 48 hours	Outpatient imaging, screening, backlog

The tiers and their definitions are set out in our published SLA. A facility targeting a tighter internal standard should read STAT radiology reads and the modality detail on STAT CT reads.

What an imaging centre outside the trauma system needs

An outpatient centre in the Houston suburbs sits outside the designation table entirely, and its problem is different. Volume arrives in daytime blocks, subspecialty demand is uneven, and the constraint is usually a reading roster that cannot flex.

Per-report billing fits that shape, because a slow week costs less and a heavy week costs proportionately more. Advanced studies still reach a fellowship-trained reader, which is hard to staff locally for four pediatric MRIs a month.

The referral pattern is worth thinking about too. An outpatient centre in a nine-county region with this much designated acute capacity competes for the same referring physicians who admit to those facilities, and report turnaround is one of the few service variables a centre can actually change. A same-day final report on an outpatient MRI is a referral argument your schedulers can make on the phone.

Three questions worth asking any vendor selling into the Houston market

Ask where the clock starts. A turnaround claim is meaningless until the vendor names both ends of the interval, and the honest answer is last-image arrival to radiologist signature. Any other starting point moves queue time off the vendor's books and onto yours.

Ask what comes back overnight. A preliminary read at 3 a.m. is work deferred to your own radiologist's morning list, which is the exact person the coverage was meant to protect. Get the answer in writing before the trial, because it is the hardest thing to change afterwards.

Ask who signs. Request the roster of physicians who will sign your reports with their Texas licence numbers, plus contract language stating that only that roster renders final reads on your patients. A vendor that cannot produce a current licence number for every signer has left a gap that becomes visible during a payer audit or a medical staff review, and by then it is your file, not theirs.

What per-report pricing looks like on a Houston invoice

One price per signed report. No minimums, no subscriptions, no platform fees, no per-seat charge, no onboarding or integration fee.

Modality and complexity set the base rate. Each faster STAT speed carries its own priority multiplier printed on the rate card and itemised on every line, so a heavy trauma week shows as a visible line your finance office can explain. The term is month to month with 30 days notice, and our per-report pricing page sets out the full model.

Credentialing sets your Houston start date, and the server room rarely does

Studies move as DICOM from your existing PACS or through secure portal upload, and reports return over HL7 or FHIR into the systems your staff already use. That work is small and it is not usually what delays a go-live.

The medical staff office is. Texas bylaws typically require credentialing and privileging of every physician who signs a final report at your facility, and that runs on your committee calendar, so start the packet on day one, in parallel with the connection work. AstraRad is HIPAA aligned, operates as a business associate under a signed BAA, and its study transfers are DICOM conformant.

When teleradiology is the wrong answer for a Houston facility

Interpretation is what moves remotely. Fluoroscopy supervision, image-guided procedures, and interventional coverage need a physician in the building, and a Level III or Level IV facility in TSA-Q that is short on those needs a local arrangement or a locums contract instead.

A facility wanting full department management, on-site staffing, and accreditation administration should buy a full-service radiology contract from a group built for it. A practice that prefers preliminary overnight drafts to overread each morning should also look elsewhere, because every report here comes back final and signed.

Getting a Houston rate card

Send your modality mix, your rough overnight and weekend volume, and your facility's designation level if it has one. A complete per-report rate card comes back within one business day, at no charge and with nothing attached.

Request a Houston rate card while the designation data above is still in front of you. The state publishes it. Any vendor you are considering should be able to talk about it.
