Abnormal Blood Chemistry
Understanding Abnormal Blood Chemistry, also known as Irregular Blood Chemistry or Abnormal Blood Test Results, is crucial for accurate clinical documentation and medical coding. This page provides information on interpreting abnormal blood test results, relevant healthcare considerations, and best practices for medical professionals dealing with abnormal blood chemistry findings. Learn about common causes, diagnostic procedures, and the importance of proper documentation for optimal patient care.
Blood test results outside the normal range, indicating a potential health issue.
Variable, depending on the specific abnormality. May include fatigue, weakness, or jaundice.

When to use each related code
| Description | When to use |
|---|---|
| Abnormal blood test results indicating a chemical imbalance. | Use when blood tests reveal abnormal levels of electrolytes, enzymes, or other substances. Consider specific findings. |
| Elevated liver enzymes indicating liver dysfunction. | Elevated ALT, AST, ALP, GGT. Suspect liver disease, monitor progression, or evaluate treatment response. |
| Abnormal kidney function shown by altered blood creatinine and urea nitrogen. | Elevated creatinine and/or BUN. Indicates impaired kidney function. Stage based on severity. |
Best-practice checklist
- ✓Document specific abnormal values.
- ✓Specify test type (e.g., CMP, BMP).
- ✓Correlate with clinical findings.
- ✓Include units of measurement.
- ✓Note date and time of blood draw.
Common pitfalls to avoid
Coding 'Abnormal Blood Chemistry' lacks specificity. Document the exact abnormal test(s) for accurate coding and billing (e.g., elevated glucose, low potassium).
Insufficient documentation linking 'Abnormal Blood Chemistry' to the patient's condition may lead to coding errors and rejected claims. CDI review needed.
'Abnormal Blood Chemistry' may signal an underlying condition. Further investigation and documentation of a definitive diagnosis are crucial for proper coding.
Best-practice tips
- 01Ensure accurate ICD-10-CM coding for abnormal blood chemistry findings.
- 02Detailed clinical documentation supports correct CPT coding for lab tests.
- 03Monitor electrolyte, liver, and kidney panels for early detection.
- 04Follow evidence-based guidelines for abnormal lab value investigation.
- 05Timely follow-up ensures appropriate management of abnormal results.
Step-by-step checklist
- 1
Review patient's complete blood count (CBC) with differential.
- 2
Check comprehensive metabolic panel (CMP) for electrolyte imbalances.
- 3
Analyze liver function tests (LFTs) and kidney function tests.
- 4
Correlate abnormal blood chemistry with patient's symptoms and medical history.
Ready-to-paste narrative
Patient presents today with abnormal blood chemistry, prompting further investigation of potential underlying etiologies. Review of systems and physical exam findings are documented elsewhere. Laboratory results reveal irregularities in the patient's blood test results, indicating an abnormal blood chemistry profile. Differential diagnoses considered include metabolic disorders, renal dysfunction, liver disease, electrolyte imbalance, and nutritional deficiencies. Specific abnormal values are detailed in the laboratory report section of this EHR. Correlation of these laboratory findings with the patient's clinical presentation will guide further diagnostic testing and treatment planning. ICD-10 codes will be assigned based on the definitive diagnosis. The patient was counseled on the significance of these findings, and a plan for follow-up testing and appropriate management strategies was discussed. Patient education materials regarding abnormal blood test results and healthy lifestyle modifications were provided. This case will be reviewed with the attending physician for further recommendations and to ensure appropriate medical coding for billing purposes. Further evaluation and monitoring are warranted to determine the underlying cause of the abnormal blood chemistry and optimize patient care.
Common questions and answers
What are the most common causes of abnormal blood chemistry results in asymptomatic patients, and how should I approach initial investigation?+
Abnormal blood chemistry results in asymptomatic patients can be caused by a variety of factors, ranging from preanalytical errors (e.g., improper sample collection, storage) and mild, transient deviations to early signs of underlying disease. Common causes include medication side effects (e.g., statins affecting liver enzymes), subclinical infections, vitamin deficiencies (e.g., vitamin D, B12), and early stages of metabolic disorders (e.g., diabetes, hypothyroidism). Initial investigation should focus on reviewing the patient's medical history, medications, and lifestyle factors. Repeat testing is often crucial to confirm persistent abnormalities and rule out preanalytical errors. Targeted follow-up tests based on the specific abnormal analyte(s) should then be considered. For instance, an isolated elevated alkaline phosphatase might warrant further investigation with GGT and bilirubin to assess liver function. Explore how implementing a standardized approach to interpreting abnormal blood tests can improve diagnostic accuracy and patient outcomes. Consider implementing a tiered laboratory testing algorithm to guide efficient and cost-effective investigation.
How can I differentiate between clinically significant abnormal liver function tests (LFTs) and benign, transient elevations in otherwise healthy adults?+
Differentiating between clinically significant and benign LFT elevations requires careful consideration of the magnitude of the abnormality, the specific LFTs affected (ALT, AST, ALP, GGT, bilirubin), and the patient's overall clinical context. Mild, transient elevations in ALT or AST, often within 2-3 times the upper limit of normal, can be seen in various non-hepatic conditions such as intense exercise, certain medications, and non-alcoholic fatty liver disease (NAFLD). However, persistent or significantly elevated LFTs, especially when accompanied by other symptoms or abnormal findings, warrant further investigation to rule out underlying liver disease. Consider the pattern of LFT abnormalities: a predominantly elevated ALP suggests cholestatic liver disease, while a predominantly elevated ALT and AST suggests hepatocellular injury. Further evaluation might include viral hepatitis serologies, autoimmune markers, imaging studies (ultrasound, MRI), and potentially liver biopsy. Learn more about the utility of non-invasive tests for assessing liver fibrosis in patients with chronic liver disease.
When should I refer a patient with abnormal electrolytes (e.g., sodium, potassium, calcium) to a specialist, and what key information should I include in the referral?+
Referral to a specialist, such as a nephrologist or endocrinologist, is indicated for patients with significant or persistent electrolyte abnormalities, especially when the underlying cause is unclear or complex. Severe electrolyte imbalances, such as severe hyponatremia or hyperkalemia, require urgent medical attention. Referrals are also warranted when the abnormality is associated with other concerning symptoms or conditions, such as cardiac arrhythmias, neuromuscular symptoms, or renal dysfunction. When making a referral, provide a concise summary of the patient's medical history, medications, relevant laboratory results (including trends over time), and any initial diagnostic workup performed. Clearly outline the specific question(s) you want the specialist to address. This ensures a streamlined and efficient consultation process, ultimately benefiting patient care. Consider implementing a standardized referral template for common electrolyte abnormalities to facilitate communication and improve patient outcomes.
