What Interqual Actually Is (And How Nurses Use It)
Interqual is a clinical decision support database created by MCG Health. It provides evidence-based criteria for utilization review. Nurses in case management, utilization review, and care coordination use it daily to justify admission levels, authorize continued stays, and plan discharges. The tool compares a patient's clinical presentation against standardized criteria to determine whether a level of care is appropriate. Most hospitals run Interqual as part of their EHR or as a standalone module. You typically access it through Epic, Cerner, or a separate web interface depending on your site's configuration. The interface itself is not particularly intuitive. It pulls from patient data but often requires manual input of assessment details that the system does not automatically capture.
Interqual Training For Nurses: Where to Find It
MCG Health offers several training pathways. The official route goes through their learning platform at m cglearning.com. You need an account, which your employer's MCG liaison usually provisions. There is no self-enrollment option that I am aware of. If your hospital uses Interqual, reach out to your utilization review manager or the MCG account rep on your contract and request login credentials for the training portal. Beyond the official portal, most facilities rely on internal training. A senior UR nurse or case manager shadows another nurse for roughly two weeks. You sit alongside someone who has been using the tool for years and watch them work through real cases. This informal method is far more valuable than the e-learning modules. The videos cover button clicks. They do not cover why you would choose one criterion over another when a case sits on the borderline. Some employers also pay for third-party courses. Professional organizations like AHIMA and ANCC occasionally offer utilization review seminars that include Interqual modules. These are helpful but expensive. If your department has budget for certification prep, look for MCG's own Nurse Utilization Review certification course. It runs online and takes about eight to twelve hours of self-paced study.
How the Tool Actually Works
Here is the basic workflow. You open a patient's chart in the EHR. You note the admitting diagnosis, current acuity, treatment plan, and any complications. You enter this into Interqual's criteria search. The system returns a determination: meets criteria, does not meet criteria, or insufficient information. The output includes the specific criterion number and a rationale snippet. That sounds straightforward. In practice it is messy. The system often returns "insufficient information" because the documentation in the chart does not match the language Interqual expects. A nurse might document "shortness of breath" but the criterion requires specific quantification like respiratory rate, oxygen saturation on a given FiO2, or work of breathing descriptors. You have to go back, request clarification from the admitting physician, and re-enter the data. That back-and-forth can consume twenty to thirty minutes per case if the documentation is thin. One concrete problem I ran into repeatedly involved borderline orthopedic admissions. A patient comes in with a hip fracture. The surgeon wants inpatient admission. Interqual criteria for surgical admission require specific wound characteristics and comorbidity severity. The chart documented "history of diabetes" but did not specify HbA1c or insulin dependence. The system defaulted to a lower level of care determination until I pulled the lab results and manually entered the comorbidity severity score. Without that detail, the automated review would have flagged the admission for denial. I learned to always check the comorbidity severity section first before submitting anything for orthopedic cases.

Counter-Intuitive Things Beginners Miss
Most new nurses treat Interqual as an answer machine. They enter data and accept the result. The reality is that Interqual is a reference framework, not a. The criteria have nuance. A criterion might say "meets criteria" but the accompanying rationale could contain qualifiers that change how you should document the case going forward. Reading only the binary output and ignoring the explanatory text is the single biggest mistake I see from people new to the tool. Another thing that catches people off guard: Interqual does not update in real time. MCG revises criteria periodically throughout the year. Your hospital's instance may be running on a version that is six to twelve months old. When a criterion changes, the lookup behavior changes too. I encountered a case where a pneumonia criterion had been recently revised to require more stringent oxygenation benchmarks. The version my hospital was running did not reflect that change yet. I spent an afternoon cross-referencing the current published criteria on MCG's website against what my system was returning, made a note of the discrepancy, and adjusted my documentation approach accordingly. Always verify which version your facility is using. Ask your MCG liaison for the effective date of your criteria set. There is also a common misconception about the "does not meet criteria" result. It does not automatically mean the patient should not be admitted. It means the patient does not meet that specific criterion for the level of care being reviewed. Physicians can still admit under medical necessity appeals. The appeal process in Interqual allows you to submit clinical justification outside the standard criteria. Most UR departments have a dedicated appeals workflow. Knowing when to escalate to an appeal versus when to adjust your documentation is a skill that takes months to develop.
Practical Tips That Actually Matter
Save time by building personal quick-reference sheets. Write down the criterion numbers for the conditions you encounter most frequently. I kept a laminated card at my desk with the top twenty criteria I used daily. Pneumonia, CHF exacerbation, sepsis, post-surgical observations, maternal care, substance withdrawal. When a new admission came in, I could go straight to the relevant section instead of searching every time. This cut my average case review time from about forty minutes down to fifteen or twenty minutes. Document specifically. Interqual criteria use precise language. If a criterion says "tachycardic at rest" and your chart says "heart rate elevated," the system will not connect those dots. Use the same terminology as the criteria whenever possible. This does not mean copying criteria verbatim into the chart. It means ensuring your clinical documentation includes the specific parameters the criteria reference. Build relationships with your medical directors. When a case is borderline and the criteria are ambiguous, having a physician who understands Interqual and is willing to document in a way that satisfies the criterion makes a huge difference. I worked with one hospitalist who routinely front-loaded his admission notes with the exact clinical parameters Interqual required. It was easier for both of us. The admissions went smoother, the denials dropped, and the nurses on the floor spent less time chasing clarification.
What Interqual Cannot Do
The tool has real limitations. It cannot account for social determinants of health unless they are documented in the chart and mapped to a specific criterion. It cannot replace clinical judgment. It does not consider institutional protocols or payer-specific requirements beyond the base criteria. Some payers modify MCG criteria with their own addenda. If your hospital contracts with multiple payers, you will find that Interqual outputs sometimes conflict with what Blue Cross or United wants to see. Your UR team should maintain a payer matrix that cross-references Interqual criteria with each major payer's modifications. Without that matrix, you will get confused results and unnecessary appeals. Also, Interqual is not designed for every level of care. It covers inpatient, skilled nursing, home health, and a few other settings. If your nurse role involves utilization review for behavioral health or substance use, Interqual may not be the primary tool. MCG has a separate Behavioral Health criteria set, but many facilities use ASAM criteria instead. Know which tool applies to your patient population before you invest time in training on the wrong one.
