CPT code 72193 – CT pelvis with contrast

Key takeaways

CPT code 72193 covers a CT of the pelvis with contrast only, while a study that adds a non-contrast series first is 72194.

The radiology report must confirm contrast administration, and a missing contrast note is a common denial trigger.

A combined abdomen-and-pelvis CT takes one code, such as 74177, rather than 72193 plus an abdomen code.

Medicare Physician Fee Schedule rates differ by component: modifier 26 (professional), TC (technical), or global billing.

Pabau’s claim validation catches missing or invalid claim details before you submit.

CPT code 72193: Official descriptor and procedure overview

CPT code 72193 describes “Computed tomography, pelvis; with contrast material(s),” a pelvis-only CT acquired after contrast is given.

The AMA’s CPT code set places it in the Diagnostic Radiology subsection. Its neighbors are CPT 72192 (without contrast) and CPT 72194 (without contrast followed by with contrast). The scan covers the bladder, uterus, ovaries, prostate, rectum, pelvic floor muscles, and nearby blood vessels.

The phrase “with contrast material(s)” means contrast was given and images were acquired in the enhanced phase. The radiology report must document the route of administration. Intravenous iodinated contrast is most common, and oral or rectal contrast may supplement it. The report must also confirm that the contrast-enhanced acquisition was completed. Without that documentation, a claim for CPT code 72193 is open to denial.

CPT 72192 vs 72193 vs 72194: Choosing the right pelvic CT code

The three pelvic CT codes map directly to the contrast protocol, so start by confirming what the radiologist performed. The protocol in the final report can differ from the one that was ordered. Anatomy matters too, because a combined abdomen-and-pelvis scan moves to its own set of codes, as the grid below shows.

When to bill 72192: No contrast was given at any point in the study. Common indications include renal calculi evaluation and patients with an iodine allergy, where contrast is contraindicated.

When to bill 72193: Contrast was administered and the study was acquired in a contrast-enhanced phase only. The report confirms “IV contrast administered” and shows no non-contrast series before it. This is the standard protocol for characterizing pelvic masses, staging cancers, and evaluating inflammatory disease.

When to bill 72194: The protocol included a non-contrast acquisition followed by a contrast-enhanced acquisition, and the report references both phases. Clinicians order it when they need to compare non-enhanced and enhanced images, such as for subtle lesion enhancement or calcification alongside a mass. A CT urogram is a separate case, because it usually covers the abdomen as well (see the CT urogram section below).

The most common selection error is billing 72193 when the report describes a without-then-with protocol, or billing 72194 when only a with-contrast phase was performed. Neither substitutes for the other, because the AMA CPT code set treats each as a distinct procedure.

How CT pelvis with contrast is performed and documented

Documentation requirements for CPT code 72193 follow from what separates it from the neighboring codes. The radiology report must contain each of the following for the claim to hold up at audit or during payer review.

1. Patient preparation: Bowel preparation (oral contrast given before the scan) is documented in the technologist’s notes or the report preamble. Some protocols omit oral contrast, and the report should still note its absence.
2. Contrast administration route and agent: The report must name the contrast agent used, such as iohexol 300 mg I/mL, 100 mL IV. It must also state the route: intravenous, oral, or rectal. It should also confirm the contrast was administered without complication.
3. Scan acquisition confirmation: The report confirms images were obtained through the pelvis following contrast administration. Phrasing such as “contrast-enhanced images of the pelvis were obtained” satisfies this requirement.
4. Radiologist interpretation: The final report must carry a licensed radiologist’s interpretation and signature. Preliminary reads alone do not support the claim.
5. Clinical indication and ICD-10 linkage: The indication section of the report should reflect the diagnosis that supports medical necessity. This diagnosis must map to an ICD-10 code on the claim.

Coders cannot supplement or correct the radiology report. If contrast administration is not documented, the appropriate code is 72192 until the radiologist amends the report. Submitting 72193 without contrast documentation in the report is incorrect coding and exposes the practice to audit risk.

When CPT 72193 is used alone vs bundled with CPT 74177

CPT 74177 describes CT of the abdomen and pelvis with contrast, and it is the correct single code for a combined abdomen-and-pelvis protocol. Its neighbors are 74176 without contrast and 74178 without then with contrast. Billing both 72193 and 74177 for the same encounter typically triggers an NCCI edit, because the combined study already includes the pelvic component.

The National Correct Coding Initiative (NCCI) publishes bundling edits quarterly. Verify the current edit status before submitting both codes for the same date of service. Edit pairs can be added, removed, or made modifier-bypassable between releases.

Some payers permit separate billing when a clinically distinct pelvis-only study answered a different anatomical question from the combined abdomen-and-pelvis study. That rationale must be documented in the medical record, and certain payers require a modifier to bypass the NCCI edit. Verify individual payer policy before submission.

CPT 72193 and CT urogram: What coders need to know

CT urography is a multi-phase protocol that images the whole urinary tract, including the kidneys, ureters, and bladder. Coders sometimes ask whether CPT code 72193 applies to a CT urogram. In most cases it does not.

A CT urogram usually opens with a non-contrast acquisition to detect calcification, followed by one or more contrast-enhanced phases. Many protocols end with a delayed excretory phase, though the phases vary by facility. The study covers the abdomen and pelvis together, so it is normally reported with one combined code. It is not billed as 72194 plus separate renal or ureteral codes. That code is usually 74178 (abdomen and pelvis, without then with contrast), or 74177 when only contrast-enhanced phases were acquired.

Radiologists and coding staff should confirm together which phases were performed and which regions were covered. Applying 72193 to a full CT urogram understates the study and may undervalue the claim. The American College of Radiology appropriateness criteria help establish which protocol was clinically indicated.

Medicare reimbursement rates for CPT 72193

Medicare payment for CPT code 72193 is based on the annual Physician Fee Schedule (PFS). It varies by geographic locality, by Medicare Administrative Contractor (MAC) jurisdiction, and by how the service is billed. Rates change each January 1, so always specify the fee schedule year when quoting a reimbursement figure.

Three billing configurations apply, and each produces a different payment amount:

Use the CMS Physician Fee Schedule lookup tool to retrieve the current non-facility and facility rates for CPT 72193 in your MAC jurisdiction. For RVU breakdowns (work, practice expense, malpractice), the FastRVU 2026 lookup provides current Medicare data without a subscription.

Hospital outpatient departments bill under the Outpatient Prospective Payment System (OPPS) using Ambulatory Payment Classifications (APCs), not the PFS. OPPS rates differ from PFS rates and are updated separately.

Prior authorization requirements for CT pelvis with contrast

Prior authorization for CPT code 72193 varies by payer, plan, and clinical indication. No universal rule applies, so coders and revenue cycle staff must verify requirements with each payer before the study is performed.

• Medicare fee-for-service: Traditional Medicare does not require prior authorization for CPT 72193, and no AUC consultation is currently required either. CMS paused the Appropriate Use Criteria program and rescinded its regulations at 42 CFR 414.94, effective January 1, 2024.
• Medicare Advantage plans: Most MA plans require prior authorization for CT imaging. Requirements differ by plan and geographic market. Submit the authorization request with the clinical indication and relevant history.
• TRICARE: TRICARE has specific coverage criteria for pelvic CT imaging. Prior authorization rules depend on the TRICARE plan type (Prime vs. Select) and whether the ordering provider is in-network. Verify requirements at tricare.mil or through the regional contractor before scheduling.
• Commercial payers: Most commercial insurers require prior authorization for CT studies ordered in outpatient settings. Radiology benefit managers (RBMs) such as eviCore or Carelon may manage the authorization process for the payer. Submit the clinical indication using the payer’s preferred clinical terminology.

Documented clinical indications that typically support medical necessity for pelvic CT with contrast include:

• Pelvic pain with an inconclusive ultrasound
• Suspected pelvic malignancy
• Staging of known gynecologic or rectal cancer
• Evaluation of inflammatory bowel disease extension
• Post-treatment response assessment

A vague indication such as “pelvic pain” without more clinical context raises the denial risk.

Common ICD-10 codes billed with CPT 72193

The ICD-10-CM diagnosis code on the claim must reflect the clinical indication documented in the radiology order and report. Payers cross-reference the diagnosis against their coverage policies and medical necessity criteria. Pelvic pain coded as R10.2 is a frequent example, and it holds up best when prior imaging results are on file. Generic or unspecified codes without supporting documentation are a leading denial trigger.

When the clinical indication involves a suspected malignancy, payers often require documentation that less invasive workup (ultrasound, clinical exam) was inconclusive before approving CT. Including that history in the authorization request reduces denial rates for oncologic indications.

Top denial reasons for CPT 72193 and how to avoid them

Radiology billing teams see the same denial patterns on pelvic CT claims again and again. Each has a preventable root cause, and the payer’s remittance names it with one of the standard denial codes.

• Wrong code selected (72192 or 72194 instead of 72193): Coders select the code before confirming the contrast protocol documented in the final report. Prevention: Audit the radiology report for explicit contrast language before coding, and never rely on the order alone.
• Missing contrast documentation: The report uses ambiguous language (“contrast was available”) rather than confirming administration. Prevention: Build a report language check into the billing workflow. Flag any report lacking “contrast administered” or equivalent language, and ask the radiologist to clarify before billing.
• Bundling with CPT 74177 without payer approval: Both codes are submitted for the same date without verifying NCCI edit status. Prevention: Check the current NCCI edit table quarterly and confirm payer-specific modifier bypass rules before billing both.
• Non-specific or mismatched ICD-10 code: The diagnosis on the claim does not support the clinical indication in the report. In other cases, an unspecified code is used when a more specific one is available. Prevention: Code from the confirmed diagnosis in the report, not the working diagnosis on the order.
• Missing prior authorization: The study was performed without the pre-authorization a Medicare Advantage or commercial payer requires. Prevention: Verify authorization requirements at scheduling, not at billing.
• Modifier errors (26 vs TC vs global): The professional component is billed as global, or the facility and the physician both bill global. Prevention: Set a modifier assignment rule at setup, based on the practice’s billing relationship with the facility.

When a denial does arrive, a set denial management process routes it, corrects it, and resubmits it before the payer’s filing limit runs out.

How claims management software reduces denials for CPT 72193

Several of the denials above start before submission, with a claim that leaves the practice missing a detail or carrying an invalid one. Without a check at that point, billing teams find out only when the payer rejects the claim.

Pabau, the practice management platform we build, includes claims management software for practices that bill US insurance. Its claim validation catches missing or invalid claim details before you submit. Claims then go out through Claim.MD, the clearinghouse Pabau integrates with, which connects to thousands of US payers.

The result is fewer claims bouncing back for missing details. Your team spends its time on coding decisions, such as 72193 versus 72194, instead of on rework.

Conclusion

Code CPT 72193 from the final radiology report, never from the order. Bill it only when the report confirms a pelvis-only, contrast-enhanced study with no non-contrast series first. When the scan also covered the abdomen, or added a non-contrast phase, a different single code applies.

That report check costs a few minutes before coding, while a denied claim costs a resubmission and a delayed payment. Practices that bill insurance in the US submit claims through Pabau and Claim.MD, so missing details surface before the claim leaves.
