From MRI CPT Codes to Payment: How Accurate CPT Coding Can Help Practices Reduce Revenue Delays

Billing for an MR process must include correct coding of procedures in the MRI billing, appropriate clinical documentation and payer requirements adherence. Mistakes involving anatomical areas and contrast authorization information result in claim delays and extra administration.

As with all codes, it’s crucial to understand what each code for diagnostic imaging and MRI means, so that radiology practices can submit the appropriate claims. But coding is not enough to ensure receipt of payment. Medical necessity, coverage, authorization, and contractual reimbursement issues also impact the outcome of claims.

In this guide, we’ll explore the typical MRI CPT codes, their billing uses, typical coding errors, and how to prevent common problems and maximize your reimbursements. It also gives you insight into how Billing Care Solutions fits into the medical billing and revenue cycle management process.

What Are MRI CPT Codes?

MRI CPT codes are used to document magnetic resonance imaging (MRI) procedures that are reported to insurance companies. CPT is a standardized code set that is kept up to date by the AMA (American Medical Association). Individual codes refer to a particular service or examination performed. X-ray procedure, contrast, and anatomical region determine the appropriate code.

​MRI CPT codes are different from ICD-10-CM codes for the diagnosis. CPT codes indicate what services are delivered; diagnosis codes indicate the reason the service was conducted or a noted condition, symptom, or disease. A brain MRI code is an example of an imaging service code. A related diagnosis code will show the diagnosed condition for which the examination was based.

Both code sets help to ensure claims are accurate. Failure to proceed with the correct procedure coding indicates that the service is not rendered correctly, and failure to support the diagnosis coding creates a medical necessity and coverage issue.

Common MRI CPT Codes for Medical Billing

Billing teams must have a succinct resource to go to for reference when looking at MRI CPT codes with common diagnostic procedures. Below are some summarized common code families with their differences. The examples below are designed to help identify initial codes. Please check the up-to-date Official CPT Descriptor before making a claim.

Brain and Head MRI CPT Codes

Brain MRI CPT codes are not the same as codes used for the orbit, face, and neck. In general, these code families cannot be used the same way. Brain imaging is not separated from other imaging exams that were performed in the neck, face, and orbit study area and are recommended to be conducted separately based on CMS guidance. Separate reporting is based on different studies, medical necessity, and requirements for coding.

Spine MRI CPT Codes

Correct anatomical region and contrast combination is required for spine MRI CPT codes. The documented examination should be checked by billing teams prior to assigning a code.

Joint and Extremity MRI CPT Codes

These MRI CPT codes separate out imaging of joints from imaging other structures in the extremities. To assign the right code family, the anatomical area documented must be determined.

Chest MRI CPT Codes

There are several different types of contrast protocols for chest MRI, as shown by the MRI CPT codes. Bills should be double-checked for coverage and approved, and documentation should back the evaluation conducted.

Abdominal MRI CPT Codes

These MRI CPT codes are all protocols (modifiers) of abdominal imaging. The coded exam should be reflective of the recorded medical examination in the medical record.

Pelvic MRI CPT Codes

Accurate procedure reporting along with appropriate diagnosis linkage is necessary for Pelvic MRI CPT codes. Staff should ensure the clinical documentation is correct for the service billed.

Confirm all the details with the latest code set from MRI CPT codes and against the rules of all the payers.

How to Select the Correct MRI CPT Codes

To select the MRI CPT codes, more than just the body part needs to be known. Billing staff should make sure that the ordered examination and performed procedure, and the supporting documents, are compared.

There are three things that need to be pointed out.

• Double-check the anatomical location first. The examinations for the cervical, thoracic, and lumbar spine are represented by distinct code families.
• Verify contrast use (second). Without-contrast and contrast exams are different for the same reason as without- and with-contrast exams.
• Third, as a final step, look at the final imaging documents. If the examination actually conducted does not match the order of the examination, staff should get appropriate clarification before submitting the claim.

As such, for instance, CPT code 72148 is used for “magnetic resonance imaging of the lumbar spine, without contrast” and CPT code 72158 is “magnetic resonance imaging of the lumbar spine, with and without contrast.” The applicable code is determined by a documented examination. Do not choose a code just because they’re in the original order. Electronic claims sent must accurately reflect the services rendered and conform with coding requirements.

How Accurate MRI CPT Coding Supports Reimbursement

Your coding accuracy allows proper claims submission that correctly describes the services. The money-making potential is readily apparent when billing efforts are tied to code validation and denial prevention, payment review, and accounts receivable management.

Reduce Coding-Related Claim Denials

Avoidable billing issues arise in several ways, including: use of incorrect procedure codes, incomplete claim information, and mismatched documentation. A pre-submission review must confirm the CPT code, linkage with the diagnosis code, the contrast protocol, any necessary modifiers, and applicable coding edits. Staff members must clear up all inconsistencies prior to transmitting the claim.

​Before correcting a claim, find out the exact reason for a payer’s claim denial. What constitutes a correct code, a proper authorization, and a correct medical necessity denial is the proper answer for each. The reasons for denial will assist managers in understanding patterns of denial. For instance, if there are multiple errors with contrast documentation, this could suggest that there is no consistency between documentation and billing.

Support Medical Necessity and Coverage Decisions

When checking MRI claims, payers consider coverage regulations and medical necessity criteria. This should be explained in the Clinical documentation as to why the examination was carried out and what service was reported as a result of the examination.

​Medicare policies, such as related Local Coverage Determinations, are available to guide on specific services. The commercial insurers have their own regulations and policy authorizations. When policy coverage may not be applicable, there is a need to check with the billing team before submission. A diagnosis code is not an automatic claim to payment.

Identify Underpayments and Reimbursement Discrepancies

Practices should check what they will be paid and what they are expected to be paid for the provided services. Accurate fee schedules, contractual terms, remittance advice, and claim-level payment records are required for this. For instance, when a short payment is made for the very same MRI, that’s an issue. Staff should review the claim and payer explanation, as well as the terms of the contract and payment rules, before making a request to reduce the claim or get a different explanation. Payment reconciliation can be used to identify payments that are meant by contract, as well as those that are underpaid. It also provides managers with actual visibility of outstanding revenue.

Improve Accounts Receivable Management

Accounts Receivable are payments due for services rendered. Unresolved claims thus pile up with unaged balances and need further follow-up. Claims that are not paid should be kept a high priority on the billing team based on age, balance, payer deadlines, and denial status. They ought to keep notes of any subsequent action and escalate unresolved issues accordingly. Some performance metrics that will be helpful are days in accounts receivable, denial rates, aging balance, and payment turnaround. These metrics are a great way to measure out issues and track changes in a practice.

Common MRI Billing Errors That Delay Payments

Errors due to contrast: errors in the inputted code opposite the examination being performed. The final imaging record should be reviewed with the appropriate CPT descriptor.

Incorrect Contrast Coding

Contrast-related errors occur when the submitted code does not match the examination performed. Staff should compare the final imaging record with the applicable CPT descriptor. A reliable workflow should flag discrepancies between the documented contrast protocol and the selected code. Staff must resolve these differences before claim submission.

Incomplete Clinical Documentation

Claim review problems include the failure to document physician orders, incomplete clinical indications, and inconsistent procedure documentation. An imaging process must have documentation requirements set up by practices for each stage of the process. If information is not available, staff should ask for help from relevant clinical processes. Patient clinical records need to be up to date. Never include unsupported information to meet demands for a claim.

Incorrect Modifier and Component Reporting

There are professional and technical elements of imaging diagnostic billing. The professional aspect typically relates to the interpretation and reporting aspect of the examination, and the technical aspect relates to the equipment, personnel, and resources used to perform the examination. Two numbers, 26 and TC, are added in appropriate situations. They may be used as needed based on the services and billing, payer requirements, and coding rules.

​Practices should check existing Medicare National Correct Coding Initiative edits and any commercial payer edits and changes. There should be a relationship between the service reported and the modifier used. Do not use the modifier as an alternative way to circumvent coding limitations.

Authorization and Eligibility Problems

Having an active insurance policy does not necessarily imply that there is authorization for an MRI exam. Prior to the proposed procedure, staff should check eligible benefits and authorization requirements, and approved service information. They should also double-check to see if they need to get some changes in the planned examination approved. Ready access to authorization data enhances staff ability to address payer questions and avoid unnecessary delays in paperwork.

A Practical Workflow for Accurate MRI Billing

A consistent workflow provides clear-cut responsibilities to staff, and less room for revenue-cycle mistakes to fall through.

Step 1: Verify Insurance and Authorization

Check coverage and discuss the payer’s authorization needs. Record the reference for approval and check this with the planned examination.

Step 2: Review Clinical Documentation

Review the Physician’s order, clinical indication, anatomical area, and contrast protocol. Clear up any inconsistencies prior to giving the final code.

Step 3: Validate MRI CPT Codes

Match the procedure being performed to the current CPT descriptor. Verify linkages to diagnosis, coding edits, and modifiers prior to claim submission.

Step 4: Scrub the Claim

Check required fields, authorization details, documentation, and payer-specific submission rules. Correct identified errors before transmitting the claim.

Step 5: Track Payment and Denial Status

Track through processing and record payment results. Explore denial science, ensure payment timeliness, and reconcile received with expected reimbursement.

This workflow sets up easily understood checkpoints. It also assists managers in determining if faults are caused by scheduling, documentation, coding, or follow-up.

How Billing Teams Can Improve MRI Revenue Cycle Performance

Choosing accurate coding is only part of the billing process. There must also be capacity in practices for scene-setting and ensuring good communication between clinical and administrative staff.

Monitor Meaningful Performance Metrics

Monitor underpayment frequency, number of days in accounts receivable, claims accepted without error, and denied claims for reasons. Set a normal baseline for working before alterations. When there are more denials for authorization, check eligibility and scheduling. If denials of coding go up, review code selection, documentation, and claim validation rules. Based on these findings, make recommendations for corrective actions. Compare across consistent reporting periods to recognize if there are improvements to performance.

Improve Communication Between Departments

With ordering providers, radiology staff, and administrative personnel all being sources of information for billing teams, it is important that all these agencies are correct. Develop a definite method for filling in information gaps. Take responsibility for documentation queries and document the outcomes. Document common mistakes and feed those mistakes to the appropriate departments. Phased training minimizes recurring issues of contrast markers, anatomical areas, and authorization data.

In-House MRI Billing vs. Outsourced Billing Services

Staffing, claim volume, denial rates, and administrative costs should all be taken into consideration when deciding between in-house and outsourced billing. The following table identifies the major practice differences that would need to be considered prior to a decision.

There’s in-house billing, which needs to be staffed, trained, and constantly updated on the payer policies, but has direct oversight. With heavy workloads, there may not be enough resources available for denial follow-up and payment recon. Medical billing services for outsourcing offer extra administrative capability. It is possible that a provider could manage denials, billing follow-up, claim coding, payment posting, coding validation, and claim submission and follow up on accounts receivable, depending on the contract.

Prior to outsourcing, evaluate staffing and cost, existing trends in denial issues, and administrative duties and balances. Consider associates with experience in radiology billing, understanding reporting requirements, detailing the process, data security, and defined roles. Outsourcing doesn’t absolve the practice of the need to accurately document the patient’s clinical record or ensure the proper management of it. The contract should detail what services the practice or the billing firm is responsible for.
