Medicare Reimbursement for Mobile Imaging: What Facilities Need to Know
Medicare covers mobile X-ray, ultrasound, and EKG — but the billing rules are specific. Here's what SNFs, home health agencies, and hospice providers need to know about coverage and compliance.
Does Medicare Cover Mobile Imaging?
Medicare Part B covers portable X-ray, ultrasound, and EKG performed at a patient's location — skilled nursing facilities, assisted living communities, private homes, and hospice settings. Portable X-ray services specifically are governed by the conditions of coverage in 42 CFR 486. For a given modality or study, confirm coverage specifics with the provider's billing team or your Medicare Administrative Contractor (MAC).
The billing rules are specific. Getting them wrong means denied claims, delayed payments, or compliance issues. Here's what you need to know.
How Medicare Covers Mobile Imaging
Mobile imaging falls under Medicare Part B as a portable X-ray / diagnostic imaging service.
The key regulatory framework:
- 42 CFR 486 — Conditions for coverage of portable X-ray services
- Medicare Benefit Policy Manual, Chapter 15, Section 80 — Portable X-ray services
- CMS Physician Fee Schedule (MPFS) — Sets reimbursement rates for specific CPT codes
The mobile imaging provider bills Medicare directly. The facility does not need to bill for the service. The provider submits claims under their own NPI using the appropriate CPT codes and place of service.
How Mobile Imaging Is Billed
A portable study is billed in components:
- The technical component — performing the study (equipment + technologist).
- The professional component — the radiologist's read and report.
- A transportation/setup component — separate from the technical and professional components — that covers bringing portable X-ray equipment to the patient's location.
The transportation component for portable X-ray is billed under the transportation HCPCS codes R0070 (single patient per trip) and R0075 (multiple patients per trip), which are current for 2026. Two rules matter: it is billed only alongside a radiology CPT code, and only when equipment was actually transported to the patient's location.
Transportation is not reimbursable for EKG. A portable supplier bills the EKG study itself (e.g., 93000 / 93005), but the transportation/setup codes (R0070, R0075, R0076, Q0092) are not payable for EKG — there is no transportation reimbursement for a portable EKG.
Exact payment amounts come from the current Medicare Physician Fee Schedule (MPFS) and vary by your MAC region — look up the current rate with your MAC or the provider's billing team. We don't publish dollar figures here: MPFS amounts change annually and by region, and the R0070/R0075 transportation allowances are under active MAC cost-analysis review.
Common CPT Codes for Mobile Imaging
Codes and descriptions are stable; rates are not — verify the current rate for each code with your MAC.
Portable X-Ray
| CPT / HCPCS Code | Description |
|---|---|
| 71046 | Chest X-ray, 2 views |
| 71045 | Chest X-ray, 1 view |
| 73502 | Hip X-ray, 2–3 views |
| 73552 | Femur X-ray, 2 views |
| R0070 | Portable X-ray equipment transportation — single patient, per trip |
| R0075 | Portable X-ray equipment transportation — multiple patients, per trip |
Mobile Ultrasound
| CPT Code | Description |
|---|---|
| 76700 | Abdominal ultrasound, complete |
| 76770 | Renal ultrasound |
| 93880 | Duplex scan, carotid arteries |
| 93971 | Duplex scan, venous (unilateral) |
Mobile EKG
| CPT Code | Description |
|---|---|
| 93000 | EKG with interpretation |
| 93005 | EKG tracing only |
| 93010 | EKG interpretation only |
EKG is billed as the study only — no transportation/setup code (R0070/R0075/R0076/Q0092) is payable for EKG.
Place of Service Codes
The place of service (POS) code tells Medicare where the exam was performed:
| POS Code | Setting |
|---|---|
| 31 | Skilled Nursing Facility |
| 32 | Nursing Facility (non-skilled) |
| 12 | Patient's Home |
| 13 | Assisted Living Facility |
| 34 | Hospice |
| 99 | Other (group homes, correctional) |
Getting the POS code wrong is one of the most common reasons for claim denials on mobile imaging services. Confirm that your mobile imaging provider uses the correct code for your facility type.
What Facilities Need to Verify
1. The Provider's Medicare Enrollment
The mobile imaging provider must be enrolled in Medicare as a portable X-ray supplier. This requires:
- Active NPI number
- Enrollment in PECOS (Provider Enrollment, Chain, and Ownership System)
- State licensure where applicable
- Compliance with 42 CFR 486 conditions
How to check: Ask the provider for their Medicare PTAN (Provider Transaction Access Number). You can also verify their enrollment through the CMS NPI Registry. On Stat Imaging, providers with Medicare enrollment show a verification badge on their profile.
2. Ordering Physician Requirements
Medicare requires that portable X-ray services be ordered by a physician (MD or DO). The order must include:
- Patient name and Medicare beneficiary identifier
- Specific exam(s) to be performed
- Clinical indication/diagnosis (ICD-10 code)
- Ordering physician's NPI and signature
Orders from nurse practitioners or physician assistants may be accepted depending on state scope-of-practice laws. Verify with your MAC.
3. Medical Necessity Documentation
Every mobile imaging exam must meet Medicare's medical necessity criteria. The key question: Is it medically necessary for imaging to be performed at the patient's location rather than at an outpatient facility?
For SNF and homebound patients, this is generally straightforward. The patient's condition makes transport impractical or medically inadvisable. But documentation should clearly state why bedside imaging is required.
Insufficient documentation is the second most common reason for claim denials, after incorrect POS codes.
Rate Updates to Watch
CMS adjusts Medicare reimbursement annually through the Physician Fee Schedule. Rather than rely on a fixed figure, watch the levers that move the numbers:
- Conversion factor. The Medicare conversion factor determines base payment amounts. Monitor the CMS final rule (typically published in November) for the upcoming year's figure.
- Geographic adjustments. Rates vary by region based on the Geographic Practice Cost Index (GPCI); higher-cost areas typically see higher reimbursement.
- Transportation allowances. The R0070/R0075 portable-X-ray transportation allowances are under active MAC cost-analysis review and are MAC-region-specific — always confirm the current allowance with your MAC.
Hospital-at-Home Expansion
The CMS Acute Hospital Care at Home waiver program continues to expand, increasing demand for mobile diagnostic services in home settings. Facilities in hospital-at-home programs should ensure their mobile imaging partners can support the program's documentation and turnaround requirements.
Prior Authorization
CMS has expanded prior authorization for advanced imaging (CT, MRI). Portable X-ray and basic ultrasound are generally exempt — but monitor for any changes to prior-auth rules that could affect mobile imaging services.
Choosing a Medicare-Compliant Provider
When evaluating mobile imaging providers for Medicare patients, confirm:
- Active Medicare enrollment and PTAN
- Correct use of place of service codes for your facility type
- Willingness to bill Medicare directly (not bill the facility)
- HIPAA-compliant image transmission and storage
- Proper ordering documentation workflows
