Coding with Confidence: A Comprehensive Guide to Navigating Uncertain Diagnoses in Inpatient Coding Guidelines

The challenge of coding uncertain diagnoses in the complex Inpatient landscape looms large, demanding a nuanced approach to ensure accuracy and compliance. As the Director of Inpatient Coding and DRG Validation Services at YES, I am excited to share insights on how our specialized services can assist hospital decision-makers and healthcare professionals in effectively addressing Inpatient coding guidelines and navigating uncertainties in the coding process.

Understanding Uncertain Diagnoses

Uncertain diagnoses in the Inpatient setting pose specific challenges that require careful consideration. While these situations are not very common, they are crucial to address.

Uncertain diagnoses refer to medical conditions or situations where the healthcare provider is not certain about the specific diagnosis or where there is ambiguity in the clinical documentation available for coding purposes. These uncertainties can arise for various reasons, and accurately coding such scenarios requires careful consideration.

Here are some situations that may lead to uncertain diagnoses:

• Unresolved Diagnostic Tests: If a patient undergoes diagnostic tests, and the results are inconclusive or pending at the time of coding, it can create uncertainty in assigning a specific diagnosis code.
• Incomplete Documentation: When the medical documentation lacks clarity or completeness, particularly in the discharge summary or other relevant records, coders may face challenges in determining a definitive diagnosis.
• Ongoing Evaluation and Observation: In some situations, a patient may be admitted for further evaluation or observation, and the final diagnosis may not be determined until later in the hospital stay.
• Ambiguous Clinical Indicators: Certain conditions may present with ambiguous clinical indicators or symptoms that make it challenging to pinpoint a specific diagnosis during the initial coding process.
• Changes in Diagnosis Post-Discharge: Sometimes, additional information becomes available after the patient has been discharged, leading to a change or clarification of the initial diagnosis.

If there is uncertainty about the patient’s discharge, coding without a complete discharge summary can lead to inaccuracies. Communication with physicians becomes paramount to solving these challenges. But, before you query, ensure that queries are initiated within the facility’s guidelines to maintain compliance and accuracy. Review our guidelines and best practices for physician queries.

Inpatient Coding Guidelines for Uncertain Diagnoses

In navigating uncertain diagnoses, adhering to coding guidelines and standards specific to the Inpatient setting is essential.

Here are the coding guidelines for the selection of principal diagnosis and reporting additional secondary diagnoses sourced from the ICD-10-CM Official Guidelines for Coding and Reporting:

“If the diagnosis documented at the time of discharge is qualified as ‘probable’, ‘suspected’, ‘likely’, ‘questionable’, ‘possible’, ‘still to be ruled out’, ‘compatible with’, ‘consistent with’, or other similar terms indicating uncertainty, code the condition as if it existed or was established. The bases for these guidelines are the diagnostic workup, arrangements for further workup or observation, and initial therapeutic approach that corresponds most closely with the established diagnosis.”

“When a diagnosis for an inpatient admission to a short-term, acute care hospital, a long-term care hospital, or a psychiatric hospital is qualified as ‘possible,’ ‘probable,’ ‘suspected,’ ‘likely,’ ‘questionable,’ ‘?’ or ‘rule out’ at the time of discharge, the condition should be coded and reported as though the diagnosis were established. Other terms that fit the definition of a probable or suspected condition are ‘consistent with,’ ‘compatible with,’ ‘indicative of,’ ‘suggestive of,’ ‘appears to be,’ ‘concern for,’ and ‘comparable with.’”

It’s important to note that there are some exceptions to the above guidelines for coding infections and illnesses. Exceptions are made for HIV infection/illness, Zika, and influenza caused by certain identified influenza viruses such as avian influenza or other novel influenza A virus. In these cases, only physician-confirmed cases should be coded. Another exception is for COVID-19, which should only be coded if confirmed by physician documentation or by a positive COVID-19 test.

Although it is preferred to report specific diagnosis codes supported by the medical documentation, using reported signs/symptoms and unspecified codes may be necessary in certain situations. If a conclusive diagnosis cannot be reached by the end of the medical evaluation, or if the clinical information available is insufficient or unavailable to assign a more specific code for a particular health condition, then it is acceptable to use an unspecified code. Only report an unspecified code that accurately reflects the patient’s condition at the time of the encounter.

Best Practices for Medical Coders

Facing coding ambiguities requires a proactive approach and adherence to best practices. Initiating queries with physicians for information and clarification is a fundamental step in resolving uncertainties.

Our firm emphasizes strong communication between Health Information Management (HIM) departments and Clinical Documentation Improvement (CDI) teams. This collaboration ensures that education is ongoing, and potential uncertainties are addressed in real-time. In addition, we maintain continuous communication with clients to avoid uncertainties in the coding process.

Continuous Education and Training Programs on Inpatient Coding Guidelines

Continuous education for medical coders is imperative, especially in the realm of uncertain diagnoses. YES highly values education and collaboration between the hospital’s staff and our coding consultants. By strengthening the understanding of clinical staff, we can achieve more defined diagnoses and reduce uncertainties.

To further foster continuous education efforts, our teams utilize Coding Roundtable sessions to review particularly difficult coding cases in order to reinforce best practices. Additionally, our Coding Question Queue allows coders to pose any question they may have from an encounter to our auditors, who will review any uncertainties and suggest a final code selection.

Medical Audits: Identifying and Rectifying Errors

Medical audits play a pivotal role in identifying and rectifying coding errors, particularly in the context of uncertain diagnoses. Auditors can catch potential revenue that might have been missed due to added documentation after the fact. For instance, during audits, our team has identified diagnoses that should have been coded but were missed due to post-encounter documentation. This proactive auditing approach protects data integrity, ensures coding quality and accuracy, and minimizes uncertainties in the coding process.
