CPT code 70360 – Soft tissue neck X-ray billing guide

Key takeaways

CPT code 70360 covers a plain-film radiograph of the soft tissue of the neck, with no contrast, fluoroscopy, CT, or MRI.

Modifier 26 (professional component) or TC (technical component) is required whenever billing is split between the radiologist and the facility.

Medical necessity must be supported by a paired ICD-10 code, and an unsupported diagnosis is the leading denial reason for this code.

Pabau, the practice management platform we build, handles submission and tracking of claims through Claim.MD from the codes your team enters.

CPT code 70360: official descriptor and procedure details

CPT code 70360 is defined by the American Medical Association (AMA) as “Radiologic examination; neck, soft tissue.” It sits in the Head and Neck subsection (70010-70559) of Diagnostic Radiology. In short, the code covers a plain-film study of the soft tissue of the neck without view restriction. It also includes no intravenous contrast, no fluoroscopic guidance, and no cross-sectional imaging.

Knowing where this code stops prevents a common billing mistake. For instance, a team orders a neck CT or MRI, then defaults to 70360 because it is the familiar neck-imaging line on the superbill. Both CT and MRI carry their own CPT codes, so each needs separate support.

What CPT code 70360 covers and what it excludes

CPT code 70360 fits plain-film evaluation of the soft tissue structures of the neck. The scope includes the epiglottis, prevertebral space, retropharyngeal space, and the air column of the airway. Typically, clinicians order it when foreign body ingestion, epiglottitis, croup, or retropharyngeal swelling is suspected. In practice, it works as a quick, low-cost screen before advanced imaging.

• Included structures: Epiglottis, prevertebral soft tissue, retropharyngeal space, supraglottic airway, and the soft tissue envelope around the cervical spine
• Typical clinical triggers: Suspected foreign body (fish bone, coin), epiglottitis (J05.1x), retropharyngeal abscess (J39.0), croup (J05.0), dysphagia workup as a first-line screen
• Not included: Cervical spine osseous structures (coded under 72040-72052), CT neck with or without contrast, MRI neck, or any fluoroscopic study

However, a swallowing-function study needs a different code. It is billed with 74230, which covers swallowing function with cineradiography or videoradiography. Likewise, a pharynx or larynx study that uses fluoroscopy and/or magnification technique is 70370 instead. Finally, films of the bony cervical spine belong to the 72040 series.

For example, sending 70360 for a fluoroscopic study causes a type mismatch that payers flag at once. Therefore, the panel below maps each neck study to its code.

CPT 70360 vs. 70370: key differences

CPT 70370 covers a radiologic examination of the pharynx or larynx, including fluoroscopy and/or magnification technique. In contrast, CPT 70360 is a plain film of the neck soft tissue. The two codes describe different imaging events, yet coders often confuse them in neck radiology billing.

CPT 70360 and 70370 cannot be billed for the same encounter without clear documentation that two distinct procedures were performed. Likewise, filing both on the same date for the same body region will trigger a bundling edit from most payers.

Documentation requirements for CPT code 70360

Radiology billing needs two layers of paperwork. The first is the ordering provider’s clinical notes, and the second is the radiologist’s formal report. Both must be present before the claim is filed, because payers deny for medical necessity in audits when either one is missing.

Claims management software with a documentation checklist built into the workflow flags a missing report at intake rather than at remittance.

Ordering provider documentation

• Clinical indication stated in plain language (e.g., “suspected retropharyngeal abscess following three days of sore throat and neck stiffness”)
• Relevant history, physical examination findings, and symptom duration
• Specific imaging order naming the body region (soft tissue neck)
• Provider credentials showing the right to order diagnostic imaging under payer policy

Radiologist report requirements

• Number of views taken (the code is not view-specific, so record every view obtained)
• Description of soft tissue structures evaluated and findings
• Radiologist’s interpretation and signature
• Date of service matching the claim

IDTF-specific requirements

Independent Diagnostic Testing Facilities (IDTFs) in Palmetto GBA’s jurisdiction follow Palmetto GBA Local Coverage Article A58559 (IDTF billing and coding) when billing CPT code 70360. The article also addresses supervision, equipment standards, and personnel qualifications for outpatient diagnostic imaging. Other MACs publish their own IDTF articles, so check the one that covers your jurisdiction.

First, the interpreting physician must meet IDTF enrollment rules. Second, the facility must also keep records of the supervising physician’s credentials available for audit. As a result, failing these rules is a denial category separate from medical-necessity issues.

ICD-10 codes that support medical necessity

Payers validate CPT code 70360 claims against the accompanying ICD-10-CM diagnosis code. In fact, an unsupported diagnosis is the single most common denial reason for this code. For reference, the table below lists commonly accepted pairings. Always check them against your MAC’s current Local Coverage Determination (LCD) before billing, because covered diagnoses vary by region.

Finally, use the CrossCoder CPT-to-ICD-10 crosswalk tool to check that your chosen diagnosis code maps to CPT code 70360 before filing. Codes marked “claim-at-risk” above are not always denied, but they need more robust clinical documentation to survive a payer audit.

Modifiers for CPT code 70360

Modifier selection for CPT code 70360 depends on how the professional and technical components are billed. For example, one entity can bill them globally, or a radiologist and a facility can split them. Getting this wrong therefore generates duplicate-billing edits or underpayment. In addition, building modifier rules into superbill preparation catches the split-billing scenario before the claim leaves the practice.

For hospital-based radiology departments, the facility typically bills TC and the radiologist group bills Modifier 26. In contrast, freestanding radiology practices often bill the global service (no modifier) when the practice owns the equipment and employs the interpreting radiologist. Also, do not append both Modifier 26 and TC to the same claim line, because the pair creates conflicting component edits.

Medicare and Medicaid reimbursement for CPT code 70360

Medicare pays for CPT code 70360 under the Medicare Physician Fee Schedule (MPFS) when a covered ICD-10 diagnosis supports medical necessity. However, payment amounts vary by location through the location adjustment factors built into the MPFS. The work RVU below comes from the CY2026 MPFS. Therefore, check payment amounts with the CMS Physician Fee Schedule lookup tool before using them for budget planning.

Because 70360 is a low-complexity plain film, its total RVU is modest. Practices should use the FastRVU lookup tool to pull the current work, practice expense, and malpractice RVU components. Then apply your locality’s conversion factor for an accurate payment estimate.

Meanwhile, Medicaid payment varies widely by state, and state Medicaid fee schedules differ from the MPFS national rate. For that reason, check your state Medicaid agency’s published fee schedule annually. Moreover, states update rates on their own cycle, which may not align with the federal October 1 ICD-10 and January 1 MPFS update calendars.

IDTFs billing CPT code 70360 in Palmetto GBA’s jurisdiction must also follow the payment rules in Palmetto GBA Local Coverage Article A58559. In addition, IDTFs are paid at the non-facility rate, and the interpreting physician must be enrolled in Medicare and meet the IDTF credential rules.

Prior authorization requirements for radiology billing

Traditional Medicare fee-for-service does not require prior authorization for CPT code 70360. However, Medicare Advantage plans and commercial payers set their own prior-authorization rules for outpatient radiology, and policies differ plan by plan and year by year. In fact, assuming Medicare Advantage mirrors traditional Medicare coverage is a common error.

• Traditional Medicare (fee-for-service): No prior authorization required for 70360 under standard CMS policy
• Medicare Advantage plans: Some plans require prior authorization for outpatient imaging, usually advanced imaging. Check each plan’s list, since plain films are rarely on it
• Commercial payers: Policies vary widely, and some require clinical decision support documentation rather than formal prior authorization
• PAMA appropriate use criteria: CMS paused the Protecting Access to Medicare Act (PAMA) appropriate use criteria (AUC) program. It rescinded the program’s regulations in the CY2024 PFS final rule. As a result, the PAMA AUC program is not currently in effect

Documenting medical necessity in the ordering note, before the imaging is performed, is the most reliable way to reduce prior-authorization friction with any payer. Maintaining radiology billing compliance records also gives you audit-ready evidence when a payer challenges necessity after the fact.

Common claim denial reasons and how to avoid them

CPT code 70360 denials cluster around six failure categories. Fortunately, most are avoidable with workflow changes at order entry rather than at the billing stage. In turn, applying denial management workflows reduces rework and shortens days in AR for radiology claims.

• Medical necessity not shown: The ICD-10 code filed does not support the imaging study. Prevention: check the diagnosis-to-code pairing in a crosswalk tool, and flag claim-at-risk diagnosis codes for documentation review before filing.
• Missing or incorrect modifier: No modifier when split billing is required, or Modifier 26 and TC filed on the same claim line. Prevention: apply a modifier decision tree at charge capture based on facility type.
• Prior authorization not obtained: A Medicare Advantage or commercial plan required pre-auth that was not sought. Prevention: run a coverage and benefit check at scheduling that includes radiology prior-auth flags.
• Ordering provider not credentialed: The referring physician is not enrolled with the payer or not credentialed at the facility. Prevention: check provider enrollment status quarterly against the payer’s provider directory.
• IDTF supervision rules not met: An IDTF billed 70360 without a supervising physician who meets its MAC’s credential standards. In Palmetto GBA’s jurisdiction, those sit in Local Coverage Article A58559. Prevention: keep a current list of credentialed supervising physicians and confirm coverage before scheduling.
• Duplicate billing with higher-level imaging: 70360 billed on the same date as a CT or MRI neck for the same clinical indication. Prevention: configure charge-capture edits to flag same-day duplicate neck imaging codes for coder review.

In short, filing a clean claim from the outset is faster and less costly than an appeal cycle. After each remittance, match the reason codes against the denial codes reference and the list above. Then address the failure category that generates the most volume first.

How Pabau keeps 70360 claims documented and trackable

Many radiology teams assemble a 70360 claim from separate places. For example, the order sits in one system, the signed report in another, and the claim status in a clearinghouse portal.

Instead, Pabau keeps the order note, the radiologist’s report, and the billing record on the same patient file. Your team enters the CPT code, modifier, and diagnosis. Pabau then submits the claim through Claim.MD and tracks its status.

With the report and the claim on one record, staff can confirm the interpretation is signed before filing. They can also follow each 70360 claim until the payer responds, instead of checking a separate portal.

Conclusion

CPT code 70360 is a straightforward plain-film code, and denials are more likely when modifier rules, ICD-10 pairings, and IDTF rules are treated as afterthoughts. Therefore, the fix starts at the point of order, where the clinical indication gets written down.

Before your next 70360 claim goes out, check three items: the signed interpretation, the split-billing modifier, and a diagnosis your MAC accepts. If one is missing, hold the claim, because a corrected filing costs less than an appeal.
