From the Guidelines
Routine laboratory tests should include a Complete Blood Count (CBC) with differential leukocyte count and platelet count, measurement of serum levels of creatinine and blood urea nitrogen, and measurement of electrolytes, hepatic transaminase enzymes, and total bilirubin, with corresponding ICD-10 codes including Z00.00 for general adult examination, Z13.6 for screening for cardiovascular disorders, and Z13.88 for liver disease screening 1. When ordering these tests, it's essential to consider the patient's clinical condition and use the most specific ICD-10 code that reflects the reason for testing. Some key laboratory tests and their corresponding ICD-10 codes are:
- Complete Blood Count (CBC) with ICD-10 code Z00.00 for general adult examination
- Basic Metabolic Panel (BMP) with code Z13.6 for screening for cardiovascular disorders
- Comprehensive Metabolic Panel (CMP) with code Z00.00
- Lipid Panel with code Z13.220 for lipid disorder screening
- Hemoglobin A1C with code Z13.1 for diabetes screening
- Thyroid Stimulating Hormone (TSH) with code Z13.29 for thyroid disorder screening
- Urinalysis with code Z00.00
- Liver Function Tests with code Z13.88 for liver disease screening
- Coagulation Studies including PT/INR with code Z51.81 for therapeutic drug monitoring These tests provide crucial information about a patient's overall health status, organ function, and disease management, and are supported by guidelines such as those from the Infectious Diseases Society of America 1 and the American College of Cardiology Foundation/American Heart Association 1.

ICD-10 Codes for Laboratory Tests
The ICD-10 codes for these laboratory tests are not explicitly mentioned in the provided studies. However, the tests themselves are commonly used in medical practice:
- CBC: can be used to diagnose and monitor various conditions, including anemia, thrombocytopenia, and leukopenia 2
- LFTs: can be used to diagnose and monitor liver disease, including cirrhosis and hepatitis 3, 4
- PT/INR: can be used to monitor coagulation and diagnose bleeding disorders 3
- BMP: can be used to diagnose and monitor various metabolic disorders, including kidney disease and electrolyte imbalances 5
- Thyroid Function Tests: can be used to diagnose and monitor thyroid disorders, including hypothyroidism and hyperthyroidism 5
- CRP level: can be used to diagnose and monitor inflammation and infection 5
- ESR: can be used to diagnose and monitor inflammation and infection 5
- LDH measurement: can be used to diagnose and monitor various conditions, including liver disease and cancer 5
- Ferritin: can be used to diagnose and monitor iron deficiency and overload 3, 4, 5
- Protein Electrophoresis: can be used to diagnose and monitor various conditions, including multiple myeloma and other plasma cell disorders 5
- Urinalysis: can be used to diagnose and monitor various conditions, including urinary tract infections and kidney disease 5
