CPT code 72198 – Pelvic magnetic resonance angiography

Key takeaways

CPT 72198 covers MRA of the pelvis only, a different procedure from the MRI pelvis codes 72195, 72196 and 72197.

One code covers every contrast protocol, so the radiology report must state which protocol was used.

Medicare coverage follows each MAC’s own policy, such as Novitas LCD L34865 and its billing and coding article A56805.

Many commercial plans manage imaging authorization through Carelon Medical Benefits Management, formerly AIM Specialty Health.

MRA codes include 3D rendering, so 76376 and 76377 are not reported with 72198.

CPT code 72198: Official descriptor and code snapshot

CPT code 72198 reports magnetic resonance angiography (MRA) of the pelvis, with or without contrast material. The American Medical Association (AMA) maintains it in the Diagnostic Radiology subsection for imaging of the spine and pelvis (72020-72295).

The “with or without contrast material(s)” phrasing is intentional. It means 72198 is a single code regardless of whether gadolinium was administered. That design simplifies code selection but shifts the documentation burden. The radiology report must state which contrast protocol was used, or the claim is unlikely to survive a payer audit.

CPT 72198 vs 72195, 72196, and 72197: Choosing the right pelvis MRI/MRA code

The four pelvis codes share an anatomic region but describe two different procedures. Payers treat MRI and MRA as distinct services with different coverage rules.

Codes 72195 through 72197 image soft-tissue anatomy such as organs, masses and ligaments. CPT code 72198 images the pelvic vasculature, producing angiographic sequences that evaluate arterial or venous flow. Billing 72198 for a routine pelvic MRI of the uterus is upcoding. Billing 72197 for a pelvic MRA ordered to evaluate iliac artery stenosis is downcoding.

Magnetic resonance venography (MRV) of the pelvis uses the same scanner but targets venous anatomy. No dedicated CPT code exists for pelvic MRV. Coders typically report 72198 with documentation specifying a venous protocol, or use the unlisted MRI code 76498, depending on payer policy. Confirm with the ordering radiologist before selecting the code.

When to use CPT 72198 vs adjacent MRA codes (74185, 70544, 71555)

Pelvic MRA sometimes captures anatomy that bleeds into adjacent code territories. The anatomic boundaries matter because payers apply different coverage rules and reimbursement rates to each region.

When a single exam covers both the abdominal aorta and the pelvic iliac vessels, code each region separately (74185 and 72198). That holds only if the ordering physician documented a distinct clinical indication for each territory. Do not code both unless the radiologist report explicitly addresses both anatomic zones with separate impressions.

The chart below puts both decisions in order: procedure type first, then vascular territory.

Modifiers for CPT code 72198

Modifier selection for 72198 follows standard radiology global billing rules. The five modifiers coders encounter most often are below.

Laterality modifiers (LT/RT) do not apply to 72198. The pelvis is a single midline anatomic region, not a bilateral paired structure. Appending LT or RT to a pelvic MRA claim can trigger a rejection at the clearinghouse or payer.

Related codes and bundling rules for CPT 72198

CPT 76377 is a standalone code, not a “+” add-on, and it is not reported with 72198. MRA codes already include the 3D rendering that produces angiographic images. CPT instructs coders not to report 76376 or 76377 with MRA codes, 72198 included.

• 3D rendering on a pelvic MRA: Leave 76376 and 76377 off the claim, even when the report describes separate workstation reconstruction. Payers deny a separate rendering line on an MRA claim as bundled.
• A second vascular territory: An MRA of another region, such as 74185 for the abdomen, is reported separately. The report must give that region its own findings and impression.
• Unlisted code 76498: Use when the pelvic MRA includes a unique protocol not captured by 72198 (for example, an investigational vascular mapping sequence). Attach a special report to the claim.

Medicare reimbursement and fee schedule for CPT code 72198 (2026)

The CMS Physician Fee Schedule lookup tool is the authoritative source for 72198 national payment rates. Rates vary by geographic adjustment factor, facility type, and whether the claim is submitted globally or split-billed. Confirm the amounts in your Medicare Administrative Contractor (MAC) jurisdiction before quoting patients.

For RVU breakdown detail, the FastRVU 2026 lookup tool provides work, practice expense, and malpractice RVU components for 72198. 72198 and 74185 carry the same 2026 work RVU (1.76); confirm in the CMS RVU file. Practices that run Pabau as their practice software can submit and track 72198 claims through its Claim.MD integration, part of its streamlined claims management.

Medicare coverage policy for pelvic MRA: LCD L34865 and Article A56805

In Novitas jurisdictions, Medicare coverage of CPT code 72198 follows Billing and Coding Article A56805, which supports Novitas LCD L34865 (MRA). Other MACs use their own LCDs, so check the policy for your jurisdiction. Coverage is not automatic. The ordering physician must document a covered indication, and the radiology report must confirm the clinical context.

Covered indications under the Novitas policy typically include:

• Evaluation of peripheral arterial disease (PAD) affecting pelvic or lower-extremity vasculature
• Pre-operative planning for vascular surgery, including aortoiliac occlusive disease
• Assessment of pelvic vascular malformations or arteriovenous fistulas
• Post-surgical surveillance of vascular reconstructions in the pelvic region
• Characterization of pelvic masses with suspected vascular involvement where CT angiography is contraindicated

Non-covered scenarios include routine screening in asymptomatic patients and repeat imaging at a clinically inappropriate interval without documented disease progression. Pelvic MRA ordered in place of a more appropriate first-line study, without clinical justification, is also not covered. Check the current LCD and article text on the CMS Medicare Coverage Database before submitting, because both are updated periodically.

Prior authorization requirements for CPT code 72198

Prior authorization requirements for 72198 vary by payer and plan year. No blanket rule applies, so radiology practices should treat prior auth as the default for commercial plans.

• Medicare: Medicare fee-for-service does not require prior authorization for 72198 at the national level, though Medicare Advantage plans often impose their own requirements. Check the specific MA plan’s policy before scheduling.
• Carelon Medical Benefits Management (formerly AIM Specialty Health): Many Blue Cross Blue Shield plans and other commercial payers manage advanced imaging authorization through Carelon. Where 72198 is on Carelon’s managed list for a payer, check before scheduling. The ordering physician then submits ICD-10 diagnosis codes, prior imaging results, and the specific vascular indication.
• Horizon Blue Cross Blue Shield of New Jersey: Horizon BCBSNJ requires prior authorization for many advanced imaging services. Check its provider portal for 72198 before scheduling.

Running insurance eligibility verification at scheduling confirms active coverage and the plan type. That tells the front desk whether a prior auth request for 72198 is needed before the exam, which avoids denials for missing authorizations.

ICD-10 diagnosis codes commonly paired with CPT 72198

Medical necessity for CPT code 72198 must be supported by an ICD-10 diagnosis code that matches a covered indication. The table below lists the most common pairings; coverage status reflects general Medicare and commercial payer guidance and may vary by MAC jurisdiction.

The CrossCoder CPT-to-ICD crosswalk tool helps verify which ICD-10 codes payers accept as medical necessity pairings for 72198. Keeping a curated list of validated 72198 and ICD-10 pairs cuts the manual lookup for each claim. A searchable ICD-10-CM code library lets coders confirm each code’s exact title and billable status before it goes on the claim.

Common denial reasons for CPT code 72198 and how to appeal

Pelvic MRA denials tend to trace back to five causes. Each one below comes with a prevention step and an appeal route.

• Medical necessity not established: The ordering physician’s documentation does not map to a covered ICD-10 indication under the MAC’s LCD or the commercial payer’s policy. Prevention: Require the ordering physician to include a specific vascular indication in the referral. Appeal: Submit the clinical notes, prior imaging, and the LCD coverage criteria together.
• Duplicate service / confusion with 72197: A claim for 72198 is denied as a duplicate when 72197 was already billed for the same date of service. Root cause: Coder or system defaulting to the MRI code family. Prevention: Flag cases ordered specifically as MRA at the scheduling stage. Appeal: Submit the radiology report confirming angiographic sequences were performed.
• Missing prior authorization: Common on commercial plans that use Carelon or another imaging benefit manager. Prevention: Build a prior auth check into the scheduling workflow for all advanced imaging. Appeal: Obtain retroactive authorization where the payer policy permits it, and submit clinical urgency documentation if the exam was emergent.
• Contrast not documented: The claim states “with contrast” but the radiology report does not specify gadolinium administration, dose, or timing. Prevention: Radiologist report template should include a mandatory contrast field. Appeal: Obtain an addendum from the radiologist confirming contrast use.
• Wrong modifier: Modifier TC submitted on a claim from a non-facility setting, or modifier 26 omitted when the radiologist does not own the scanner. Prevention: Verify global vs. split billing at the practice level before claim submission.

Documentation checklist for a successful CPT code 72198 claim

A complete radiology report and referral package heads off each denial cause above. Use this checklist before submitting.

• Radiology report: Confirm the report states MRA (not MRI) and identifies the pelvic vascular anatomy examined. It must document the contrast protocol (none, gadolinium with dose and timing, or pre-and-post gadolinium). It also needs a clinical impression specific to the vascular indication.
• Ordering physician documentation: Clinical notes must include the specific vascular diagnosis or symptom, relevant prior workup, and the reason conventional imaging is insufficient.
• ICD-10 pairing: At least one ICD-10 code that maps to a covered indication in the MAC’s LCD must appear on the claim. Generic codes (e.g., unspecified abdominal pain) are insufficient without a supporting vascular diagnosis.
• Prior authorization number: For payers using Carelon or an in-house prior authorization program, the authorization number must appear in the appropriate claim field. A missing number typically means a denial.
• Modifier assignment: Confirm global vs. split billing before the claim is generated. Modifier 26 requires separate radiologist and facility claims.
• No separate 3D rendering line: Confirm 76376 and 76377 are not on the claim. The MRA code already includes post-processing, so a separate rendering charge is likely to be denied as bundled.

A clean claim submission checklist embedded in the billing workflow catches these items at creation rather than during denial review. For patients who file with their insurer themselves, Pabau can produce a downloadable superbill from the visit.

How Pabau’s claims management supports CPT 72198 billing

A pelvic MRA claim passes through several hands. The front desk checks coverage, the radiologist reports the study, and a coder builds the claim from the report and the referral. Each handoff can drop an authorization number or swap in an MRI code.

Pabau keeps those steps in one system. Insurance eligibility runs through Claim.MD before the visit. Each claim is scrubbed for missing or invalid details before it leaves Pabau, then submitted and tracked through the same integration.

The claims dashboard shows each claim’s status and how many days it is overdue. US practices can also post payments straight from ERA files. Your billing team spends less time chasing claims and more time fixing the few that need attention.

Conclusion

The decision that protects a 72198 claim happens before the scanner runs. Confirm at ordering that the study is angiographic and pelvic, and the code, the diagnosis pairing and the authorization tend to follow.

The trade-off is front-loaded work. A few minutes on the referral and the contrast field cost far less than an appeal, which takes longer and pays later.

Pabau’s claims management helps teams submit and track claims through Claim.MD, so a clean 72198 claim reaches the payer without re-keying. Book a demo to see how it fits a radiology or multi-specialty practice.
