What Do You Do When ‘Screening’ Isn’t Supported by the Medical Record?
Do not assume the heading on the procedure report tells the entire story. Documentation drives coding. As a medical coder, you rely on the provider’s note to determine whether a service qualifies as preventive or diagnostic. But what happens when the documentation sends mixed messages? For instance, one of the most common challenges in gastroenterology is a colonoscopy documented as a “screening” procedure, while the body of the note tells a different story. Perhaps the patient reports rectal bleeding in the history of present illness (HPI), chronic diarrhea appears in the assessment, or iron deficiency anemia prompted the referral. Although the procedure may have been labeled as screening on the order or procedure report, the clinical documentation suggests the physician was evaluating a symptom or abnormal finding. These inconsistencies can lead to claim denials, compliance concerns, inaccurate reimbursement, and audit risk. Knowing how to identify conflicting documentation and when to seek clarification can help ensure that your coding accurately reflects the patient’s clinical presentation. Understand Why the Entire Record Matters You may want to rely on the procedure indication listed at the top of the colonoscopy report — but don’t fall into this trap. You should never base coding decisions on a single phrase in the medical record. Instead, review the entire encounter, including: These sections should tell a consistent clinical story. If they do not, you may need to query the provider before assigning codes. According to the ICD-10-CM Official Guidelines for Coding and Reporting, code assignment is based on the provider’s documentation of the patient’s condition and the reason for the encounter. Likewise, CPT® coding depends on the service performed and the documented clinical circumstances. What if the ‘Screening’ and the Clinical Picture Don’t Match? A colonoscopy performed on an asymptomatic patient to detect colorectal cancer is considered a screening examination. A colonoscopy performed because the patient has symptoms or an abnormal clinical finding is generally diagnostic, even if the provider documents “screening” as the procedure indication. As a coder, your responsibility is to recognize when those two descriptions conflict. Example: Rectal Bleeding Hidden in the HPI — A 62-year-old patient is referred for a colonoscopy. The procedure report lists the indication as “Screening colonoscopy.” However, the history documents intermittent rectal bleeding for the past three months. The assessment states that the colonoscopy is being performed to evaluate hematochezia. The physician performs a diagnostic colonoscopy without intervention. What should you do? If you said report 45378 (Colonoscopy, flexible; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure)) with Z12.11 (Encounter for screening for malignant neoplasm of colon) because the procedure report states “screening,” then you are making a big mistake. Correct approach: Before assigning codes, review the conflicting documentation. Because the history and assessment indicate the physician performed the colonoscopy to evaluate rectal bleeding, the encounter appears diagnostic rather than preventive. If the provider’s intent is unclear, query the physician before reporting the claim. If the physician confirms the colonoscopy was performed to evaluate the patient’s symptoms, report the appropriate symptom diagnosis, such as K62.5 (Hemorrhage of anus and rectum), rather than Z12.11. The label “screening” should not outweigh documentation demonstrating that the procedure was performed to evaluate symptoms. Watch out for Symptoms Buried in the Medical Record Conflicting documentation is not always obvious. Sometimes symptoms appear only once in the record, while every other section refers to a screening examination. Watch for documentation, such as: These details may change the reason for the encounter. Do not assume the heading on the procedure report tells the entire story. Example: Iron Deficiency Anemia Drives the Procedure — A 70-year-old patient is scheduled for a colonoscopy. The procedure indication states “Average-risk screening.” The office note documents newly diagnosed iron-deficiency anemia. The gastroenterologist writes that they are performing the colonoscopy to identify a possible gastrointestinal bleeding source. The examination is completed without biopsy. Correct approach: In this example, you can report 45378. If the documentation supports that the procedure was performed to evaluate the patient’s anemia, use D50.9 (Iron deficiency anemia, unspecified), or the more specific documented diagnosis, rather than Z12.11. Because the physician is investigating a clinical problem, the colonoscopy is generally considered diagnostic. Identify How Auditors Evaluate Conflicting Documentation Auditors rarely focus on a single sentence. Instead, they evaluate whether the medical record consistently supports medical necessity and the codes submitted on the claim. For example, an auditor may compare the following records: If these records tell different stories, the claim may be questioned. For example, a claim submitted with Z12.11 may receive additional scrutiny if the office note repeatedly discusses abdominal pain and weight loss without explaining why the procedure is still considered preventive. Consistency throughout the record is one of the strongest defenses during an audit. When Should You Query the Provider? Not every discrepancy requires a physician query. However, a query is appropriate when the documentation contains conflicting or ambiguous information that affects code assignment. Example: Competing Indications — The procedure report states, “Indication: Screening colonoscopy.” The assessment states, “Positive FIT requiring evaluation.” The HPI documents no symptoms. So, here’s the question: Should you code this as screening or diagnostic? Correct approach: The answer depends on the physician’s documented intent. Because Medicare now considers a follow-on colonoscopy after a positive covered stool-based screening test to be part of the complete colorectal cancer screening process, the provider’s documentation should clearly establish whether the procedure represents completion of screening or evaluation of another clinical concern. If the documentation is unclear, submit a compliant physician query rather than making assumptions. Follow These Query Best Practices When clarification is needed, make sure your query checks all these boxes: An effective query might read: “The colonoscopy report lists the indication as screening; however, the history documents rectal bleeding for three months. Can you clarify the primary reason the colonoscopy was performed?” A compliant query seeks clarification without leading the provider toward a particular diagnosis or reimbursement outcome. Learn the Compliance Risk of Misrepresenting the Encounter You may be tempted to code every colonoscopy labeled as “screening” as preventive. Doing so may create compliance concerns if the documentation supports a diagnostic examination instead. Potential consequences include: Likewise, coding every colonoscopy after a positive FIT as diagnostic without reviewing current Centers for Medicare & Medicaid Services (CMS) guidance could also result in inaccurate reporting. Your role is to translate the physician’s documentation into accurate codes, not to reinterpret the clinical circumstances or select codes that maximize reimbursement. Find out How to Help Providers Improve Documentation Many documentation issues occur because providers use electronic health record (EHR) templates that automatically populate “screening colonoscopy.” Education can reduce these inconsistencies. Consider encouraging providers to document: Even a single sentence clarifying the physician’s intent can eliminate coding uncertainty. Follow This Documentation Checklist Before coding a gastroenterology procedure, confirm that the medical record clearly identifies: Final Takeaway In gastroenterology coding especially, a procedure labeled as “screening” is not always a screening examination for coding purposes. You should evaluate the complete medical record, identify conflicting documentation, and seek clarification whenever the physician’s intent is unclear. By recognizing inconsistencies early, submitting compliant provider queries, and coding according to the documented clinical circumstances rather than isolated phrases, you help protect your organization from denials and audit risk while ensuring claims accurately reflect the care provided.
