A post-discharge query is needed to obtain a more specific principal diagnosis with the highest level of severity of illness (SOI) and risk of mortality (ROM) for this patient. The discharge diagnosis of health care associated pneumonia (HCAP) is not specific enough to capture the etiology, site, and severity of the pneumonia. Based on the clinical indicators in the case scenario, such as the history of aspiration, the chest x-ray findings, the elevated white blood count, the fever, and the antibiotic treatment, a more specific diagnosis of aspiration pneumonia would be appropriate. Aspiration pneumonia is a type of pneumonia that occurs when foreign material, such as food or vomit, is inhaled into the lungs, causing inflammation and infection. Aspiration pneumonia has a higher SOI and ROM than HCAP because it is associated with more complications and poorer outcomes 1.

Additionally, the discharge diagnosis of altered mental status is vague and does not reflect the underlying cause or severity of the condition. Based on the clinical indicators in the case scenario, such as the fever, the low sodium level, the moaning and disorientation, and the venous blood gas results, a more specific diagnosis of septic encephalopathy would be appropriate. Septic encephalopathy is a type of delirium that occurs when sepsis affects the brain function, causing confusion, agitation, or reduced consciousness. Septic encephalopathy has a higher SOI and ROM than altered mental status because it indicates a systemic inflammatory response and multi-organ dysfunction 2.

Furthermore, the discharge diagnosis of respiratory distress is also vague and does not reflect the underlying cause or severity of the condition. Based on the clinical indicators in the case scenario, such as the shortness of breath, the accessory muscle use, the respiratory rate, and the bilevel positive airway pressure treatment, a more specific diagnosis of acute hypoxemic respiratory failure would be appropriate. Acute hypoxemic respiratory failure is a type of respiratory failure that occurs when there is insufficient oxygen exchange in the lungs, causing low oxygen levels in the blood. Acute hypoxemic respiratory failure has a higher SOI and ROM than respiratory distress because it indicates a life-threatening condition that requires mechanical ventilation or oxygen therapy 3.

Finally, based on the clinical indicators in the case scenario, such as the fever, the elevated white blood count, and the antibiotic treatment, a diagnosis of sepsis should also be included in the query. Sepsis is a serious complication of infection that occurs when the body’s immune system overreacts to an infection and causes widespread inflammation and organ damage. Sepsis has a high SOI and ROM because it can lead to septic shock or death if not treated promptly 4.

Therefore, a post-discharge query should ask the provider to confirm or rule out aspiration pneumonia, hyponatremia (low sodium level), septic encephalopathy, and sepsis with acute hypoxemic respiratory failure as possible diagnoses for this patient. These diagnoses would result in a more specific principal diagnosis with the highest level of SOI and ROM for this patient.

An Excludes 2 note in ICD-10-CM indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes 2 note appears under a code, it is acceptable to use both the code and the excluded code together to completely describe the condition. For example, under code R05 Cough, there is an Excludes 2 note for whooping cough (A37.-). This means that a patient can have both a cough and whooping cough at the same time, and both codes can be used together to capture the full clinical picture.

A CC/MCC capture rate is a metric that measures the percentage of cases that have at least one complication or comorbidity (CC) or major complication or comorbidity (MCC) coded in the medical record. This metric is important for a CDI program because CCs and MCCs affect the severity of illness, risk of mortality, and reimbursement of the cases under the Medicare Severity-Diagnosis Related Group (MS-DRG) system. A higher CC/MCC capture rate indicates a more accurate and complete documentation of the patient’s condition and the resources used to treat them. A CDI program can use this metric to monitor the effectiveness of its queries, education, and feedback to the providers and coders. A CDI program can also compare its CC/MCC capture rate with national or regional benchmarks to identify areas of improvement or best practices 2.

Combination codes are used to classify two diagnoses, a diagnosis with a manifestation, or a diagnosis with an associated complication. A complication is a condition that arises during the hospital stay that prolongs the length of stay by at least one day in approximately 75 percent of cases1. Complications may affect payment and severity of illness and risk of mortality classifications. Examples of combination codes that include a diagnosis with an associated complication are:

• I50.23 Acute on chronic systolic (congestive) heart failure
• K57.21 Diverticulitis of large intestine with perforation and abscess with bleeding
• O34.211 Maternal care for incompetent cervix with cerclage, first trimester

A diagnosis that is an integral part of a disease process is not a valid option for combination codes, because it does not represent a separate or additional condition that needs to be coded. For example, chest pain is an integral part of acute myocardial infarction and does not require a separate code.

A diagnosis with an associated procedure is not a valid option for combination codes, because procedures are coded separately from diagnoses using ICD-10-PCS codes. For example, appendicitis with appendectomy is not a combination code, but rather two codes: one for the diagnosis (K35.80 Acute appendicitis without perforation or gangrene) and one for the procedure (0DTJ4ZZ Resection of appendix, percutaneous endoscopic approach).

A diagnosis with a sequelae or late effect is not a valid option for combination codes, because sequelae or late effects are coded separately from the original condition using the appropriate code from category B90-B94 Sequelae of infectious and parasitic diseases or category I69 Sequelae of cerebrovascular disease, followed by the code for the specific condition2. For example, hemiplegia following cerebral infarction is not a combination code, but rather two codes: one for the sequelae (I69.351 Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side) and one for the original condition (I63.9 Cerebral infarction, unspecified).

A leading query is one that suggests a specific diagnosis, condition, or treatment to the provider, or implies that a certain response is desired or expected. A leading query can compromise the integrity and accuracy of the documentation and the coded data, and may also raise compliance and ethical issues. A query should be non-leading, meaning that it presents the facts from the health record without bias or influence, and allows the provider to use their clinical judgment to determine the appropriate response.

The query in the question is leading because it implies that the patient’s CHF is systolic by asking a yes/no question that only offers one option. A non-leading query would ask an open-ended question that offers multiple options, such as “What type of CHF does this patient have?” or “Please specify the type of CHF: systolic, diastolic, or combined.”

Hospital-acquired condition pay provisions apply only to inpatient prospective payment system hospitals because they are subject to the CMS policy that reduces payments for cases with conditions that were not present on admission. This policy is intended to encourage hospitals to improve the quality of care and prevent avoidable complications. Other types of hospitals, such as critical access hospitals, long-term acute care hospitals, and inpatient psychiatric hospitals, are not affected by this policy and are paid based on different methodologies.

According to AHIMA, clinical documentation is at the core of every patient encounter and it must be meaningful to accurately reflect the patient’s disease burden and scope of services provided. In order to be meaningful, the documentation must be clear, consistent, complete, precise, reliable, timely, and legible1. Reliability is one of the criteria for clinical documentation that means the content of the record is trustworthy, safe, and yielding the same result when repeated1. Reliability ensures that the documentation is consistent with the clinical evidence and reasoning, and that it can be verified by other sources or methods. Reliability also implies that the documentation is free from errors, omissions, contradictions, or ambiguities that could compromise its validity or usefulness1.

This response provides the highest level of specificity for the patient’s diagnosis because it includes the following elements:

• The type of heart failure: diastolic, which means the heart has difficulty relaxing and filling with blood during diastole, resulting in increased filling pressures and pulmonary congestion. Diastolic heart failure is also known as heart failure with preserved ejection fraction (HFpEF), which is defined as an ejection fraction of 50% or higher 2.
• The acuity of heart failure: acute on chronic, which means the patient has a history of chronic heart failure that has worsened acutely due to a precipitating factor, such as infection, ischemia, arrhythmia, or medication noncompliance. Acute on chronic heart failure is associated with higher mortality and morbidity than stable chronic heart failure 3.
• The associated conditions: hypertensive renal disease and CKD 3, which indicate that the patient has kidney damage and reduced kidney function due to high blood pressure. CKD 3 is the third stage of chronic kidney disease, which is characterized by a glomerular filtration rate of 30 to 59 mL per minute per 1.73 m2 4.

The other responses are less specific because they either omit or misrepresent some of these elements. For example, response B incorrectly states that the patient has systolic heart failure, which is contradicted by the echocardiogram result. Response C does not specify whether the heart failure is chronic or acute on chronic, which has implications for treatment and prognosis. Response D does not specify the type of heart failure, which affects the coding and classification of the condition.
