Chest X-rays are one of the most frequently performed services in radiology practices or hospitals. They are a major source of revenue for healthcare providers. However, even with their simplicity, many chest X-ray claims are denied.
CPT code 71045 represents the simplest form of chest X-ray. In this guide, we explain what this code is and how to bill it correctly. So, let’s start right away.
CPT Code 71045 – Description
CPT code 71045 is defined as:
“Radiologic examination, chest; single view.”
As evident from the definition, 71045 is a radiology billing code. It is used to bill the most basic form of chest X-ray. 71045 is part of a group of four codes that are used for chest X-rays. These codes are:
- 71045: Radiologic examination, chest; single view
- 71046: Radiologic examination, chest; 2 views
- 71047: Radiologic examination, chest; 3 views
- 71048: Radiologic examination, chest; 4 or more views
However, the important point that many billers miss is that CPT code 71045 is only for diagnostic and treatment purposes. You cannot use it for routine scans.
Appropriate Use Cases for CPT Code 71045
In most cases, chest X-rays are taken from more than one view. However, that doesn’t mean single-view imaging has become obsolete. The following are a couple of real-world scenarios in which CPT code 71045 can be used:
Bedside and Portable Exams
The most common application for CPT 71045 is the portable chest X-ray performed on unstable patients. In intensive care units (ICUs) or emergency rooms, patients may be too ill to stand for a posteroanterior (PA) view or be moved for a lateral view. In these cases, a portable anteroposterior (AP) view is captured at the bedside.
Since only one view is obtained, 71045 is the correct code.
Line and Tube Placement
After the insertion of medical devices, like endotracheal tubes, central venous catheters, or nasogastric tubes, verification of placement is mandatory. A single AP view is sufficient to visualize the tip of the catheter or tube relative to anatomical landmarks.
Ordering a two-view study for simple line placement verification would largely be considered medically unnecessary. So, CPT code 71045 is appropriate to use in these cases.
Modifiers to Append with CPT Code 71045
The following are some of the most frequently used modifiers with CPT code 71045:
| Modifier | Name | Description |
|---|---|---|
| TC | Technical Component | Applied when billing only for the technical aspects, including equipment, supplies, and the technician’s services. |
| 26 | Professional Component | Used when billing only for the physician’s interpretation and report. |
| 52 | Reduced Services | Applied when the full service cannot be completed due to patient limitations or extenuating circumstances. |
| 59 | Distinct Procedure | It is used when the procedure is distinct from other services performed on the same day. |

You can check the exact reimbursement rate for your MAC locality via the PFS Lookup Tool.
Follow the Medicare Bundling Rules
According to the Medicare NCCI edits, you are not allowed to bill Medicare separately for a single-view chest X-ray if the radiologic exam was performed to confirm the proper positioning of:
- A central flow-directed catheter (e.g., Swan-Ganz), represented by CPT code 93503.
- An emergency endotracheal tube, represented by CPT code 31500.
- A chest tube, represented by CPT codes 32550 and 32551.
- A central venous catheter, represented by CPT code 36556.
This is because Medicare considers the chest X-ray an included service and bundles its reimbursement into the primary procedure’s payment.
