CPT code 74019 – Abdominal X-ray, 2 views

Key takeaways

CPT 74019 reports an abdominal X-ray with exactly two views. Bill 74018 for one view, 74021 for three or more, and 74022 when a chest view is added.

Append modifier 26 or TC when one party owns the equipment and another interprets the study. A missing or wrong modifier is a frequent denial cause.

The 2026 national Medicare rate for 74019 is about $36 before locality adjustment, and the professional component is roughly 30% of it.

Pabau, the practice management platform we build, sends claims through the Claim.MD clearinghouse with eligibility checks before the study and remittance tracking after it.

CPT code 74019: official descriptor and quick reference

The American Medical Association publishes the official descriptor for CPT code 74019 as Radiologic examination, abdomen; 2 views. It reports a plain-film abdominal X-ray with exactly two views, interpreted and documented in a signed report. The code sits in the Radiology section of the CPT code set, under Diagnostic Radiology (Diagnostic Imaging) Procedures of the Abdomen (74018-74190).

What CPT code 74019 covers: clinical scope and indications

CPT code 74019 applies when a radiologist or physician performs a plain-film radiographic study of the abdomen using two projections. The study images the abdominal cavity, including the bowel gas pattern, soft tissue outlines, bony pelvis, and any radiopaque foreign bodies or calcifications.

Common clinical indications that support medical necessity for CPT 74019 include:

• Acute abdominal pain with suspected bowel obstruction or perforation
• Evaluation of suspected foreign body ingestion
• Abdominal distension or unexplained nausea and vomiting
• Follow-up of known renal calculi or abdominal aortic aneurysm
• Pre- and post-procedure verification (e.g. nasogastric tube placement)

The CPT descriptor does not name which projections to acquire. It requires two views, obtained and documented. In practice, the AP supine and upright abdomen combination is the most common pairing. When a patient cannot stand, a left lateral decubitus view replaces the upright projection. A series of three or more abdominal views is reported with 74021, not 74019.

CPT 74019 vs 74018 vs 74021: choosing the right code

A frequent coding error in abdominal X-ray billing is picking the wrong code within the 74018-74022 family. View count decides the code, not anatomy or clinical indication. The chart below maps each view count to its code and its 2026 national Medicare rate.

Bill 74019 only when the radiology report confirms that two views were acquired and interpreted. A single-view study belongs under 74018, and upcoding it to 74019 exposes the practice to audit risk. A three-view series billed as 74019 is undercoded, because 74021 is the correct code.

How CPT 74019 is performed and documented

Accurate documentation is the bridge between the procedure performed and a paid claim. For CPT 74019, the radiology report must support three elements. It has to show that the abdomen was imaged, that two views were obtained, and that a physician interpreted and signed the study.

1. Image acquisition: The technologist positions the patient for the AP supine projection, then acquires the second view (upright or lateral decubitus). Both projections are captured on separate images.
2. Radiologist interpretation: The interpreting physician reviews both projections and dictates findings, including assessment of bowel gas pattern, calcifications, soft tissue masses, and osseous structures.
3. Report documentation: The written report explicitly states the number of views obtained (e.g. “AP supine and upright abdomen, 2 views”). This phrase is the documentation anchor for the claim.
4. Clinical indication: The order and report both reference the diagnosis or symptom prompting the study. This ICD-10 code must appear on the claim and must support medical necessity.
5. Supervising physician signature: For split-billing settings, the interpreting physician’s signature establishes the professional component separately from the technical acquisition.

Modifier usage for CPT 74019: professional, technical, and global billing

Radiology codes, including CPT 74019, can be billed globally or split into professional and technical components. The choice depends on who owns the equipment and who performs the interpretation. Getting modifiers right is especially important for hospital outpatient and independent imaging center settings.

Physician offices that own their own X-ray equipment and employ the interpreting radiologist bill globally. When the hospital provides the equipment and the radiologist bills separately, the hospital bills 74019-TC and the radiologist bills 74019-26. Billing both globally in this scenario results in a duplicate-claim denial.

Medicare reimbursement for CPT code 74019

Medicare Part B reimburses CPT code 74019 under the CMS Physician Fee Schedule. Rates are set annually and adjusted by geographic practice cost index (GPCI) factors, so the allowed amount varies by MAC jurisdiction and locality.

Abdominal plain-film codes like 74019 are low-RVU studies. For 2026, 74019 carries 1.08 total RVUs, which works out to a national global rate of about $36 at the non-QP conversion factor of $33.4009. The professional component (modifier 26) is 0.32 RVUs, about 30% of the global rate, and the technical component (TC) carries the rest.

Locality adjustments move these figures, and CMS resets them each calendar year. Check the CMS MPFS Look-Up Tool before quoting rates to patients or negotiating commercial contracts.

For practices that send claims through Pabau’s Claim.MD clearinghouse integration, real-time eligibility checks (270/271) confirm Medicare Part B coverage and patient cost-sharing before the study. That cuts down on billing surprises after the visit.

Payer requirements and prior authorization for CPT 74019

Medicare generally does not require prior authorization for abdominal radiographs. Commercial payers are less consistent. Some managed care plans do require pre-authorization for outpatient diagnostic imaging, including plain-film abdominal studies ordered in non-emergency settings.

• Check individual payer policies: Authorization requirements vary by plan year and state. Never assume Medicare rules apply to a commercial plan.
• Document clinical urgency: Emergency and urgent-care orders typically bypass PA requirements, but the documentation must reflect the acute clinical scenario.
• Use the ordering ICD-10 code strategically: Payers review medical necessity based on the paired diagnosis code. A vague ICD-10 selection (e.g. R10.9 for unspecified abdominal pain) may trigger additional review; a specific code aligned to the clinical indication reduces that risk.
• Retain the order and clinical notes: A later denial for lack of medical necessity is appealed with the ordering physician’s documented clinical rationale.

Common ICD-10 codes paired with CPT 74019

The ICD-10-CM diagnosis code paired with CPT 74019 must support the medical necessity of the study. Payers cross-reference the diagnosis against their Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) to determine whether the imaging was appropriate.

When ordering a study for a non-specific symptom like R10.9, document the clinical reasoning in the order or encounter note. Payer LCDs for abdominal radiology often list covered diagnoses explicitly; check the applicable MAC policy before billing.

Claim denial reasons for CPT 74019 and how to avoid them

Four denial reasons come up most often for CPT 74019. Each one is preventable with front-end checks rather than appeals after the fact.

For practices with recurring 74019 denials, a denial management workflow that tracks denials by reason and payer shows patterns faster than reading single remittances. With electronic remittance advice (ERA/835), the claim adjustment reason codes arrive in a structured form. That lets your team route each denial to the right person without manual sorting.

Submitting a clean claim the first time is always faster than appealing a denial. For abdominal X-ray billing, that means confirming view count, modifier logic, and ICD-10 pairing before the claim leaves the practice.

How Pabau supports radiology billing workflows

Radiology billing holds up when the report, the code, and the claim agree. Most practices still check eligibility in one portal, build claims in another, and post remittances by hand. Pabau’s claims software for radiology keeps those steps in one place, from the eligibility check to the remittance.

Through the Claim.MD clearinghouse integration, Pabau generates CMS-1500 claims from your invoices and sends them to thousands of US payers. Eligibility checks (270/271) run before the visit, and ERAs are matched back to the claims they pay. Denied claims are flagged for rework, so your team sees which 74019 claims need attention without sorting remittances by hand.

Your coders still assign the code and modifier from the signed report. Pabau keeps the claim, its status, and its remittance together, so a view-count or modifier denial is easy to trace back to its source. If the revenue side is new to you, our guide on how medical billing works covers the full cycle.

Submit and track radiology claims in one place

Pabau sends your CMS-1500 claims through Claim.MD, checks patient eligibility before the study, and matches ERAs back to each claim. See how it works in a live demo.

Conclusion

CPT 74019 pays for one specific study: two abdominal views, interpreted and documented in a signed report. Read the view count off the report before you assign a code, and let it decide between 74018, 74019, 74021, and 74022.

Get that step right, add the correct modifier in split-billing settings, and pair a specific ICD-10 code. Most 74019 denials then never happen. The cost is a few seconds of report review per claim, which is far cheaper than an appeal.
