Range Overview
high priority
The ICD-10 code range R80-R89 pertains to abnormal findings on examination of blood, without a diagnosis. These codes are used when laboratory tests reveal abnormal results that are not yet diagnosed or linked to a specific condition. They cover a broad spectrum of abnormalities, such as abnormal levels of blood substances, abnormal coagulation profile, and abnormal immunological findings in serum.
Key Usage Points:
- •These codes are used when abnormal blood findings are discovered but not yet diagnosed.
- •They cover a wide range of abnormalities, including abnormal levels of blood substances.
- •R80-R89 codes are not used for diagnosed conditions.
- •The codes should be used in conjunction with other codes to provide a complete clinical picture.
- •They are often used in preliminary stages of diagnosis.
Coding Guidelines
When to Use:
- ✓When laboratory tests reveal abnormal blood findings without a specific diagnosis.
- ✓When abnormal levels of blood substances are found.
- ✓When there are abnormal immunological findings in serum.
- ✓In cases of abnormal coagulation profile.
- ✓When there are other abnormal findings in blood.
When NOT to Use:
- ✗When a specific diagnosis has been made.
- ✗When the abnormal finding is not related to blood.
- ✗When the abnormal finding is related to urine or other body fluids.
- ✗When the abnormal finding is related to a specific disease or condition.
- ✗When the abnormal finding is related to a genetic disorder.
Code Exclusions
Always verify exclusions with the latest ICD-10 guidelines and updates.
Documentation Requirements
Documentation for R80-R89 codes should be thorough and precise. It should clearly state the abnormal finding, the specific laboratory test performed, and any relevant clinical information. The documentation should not include a specific diagnosis.
Clinical Information:
- •Specific abnormal finding
- •Type of laboratory test performed
- •Relevant clinical information
- •Any related symptoms or conditions
- •Follow-up plans or further testing
Supporting Evidence:
- •Laboratory test results
- •Clinical notes
- •Patient history
- •Imaging or other diagnostic reports
Good Documentation Example:
Patient's blood test revealed elevated white blood cell count. Further testing is planned.
Poor Documentation Example:
Abnormal blood test.
Common Documentation Errors:
- âš Not specifying the abnormal finding
- âš Including a diagnosis
- âš Not including relevant clinical information
- âš Not documenting the type of laboratory test

Coding Complexity
Medium
Complexity Rating
The complexity of R80-R89 codes is considered medium due to the need for a thorough understanding of the specific abnormal finding, knowing when to use these codes versus a specific diagnosis code, keeping up with updates and changes to the ICD-10 guidelines, and determining the correct code based on the laboratory test performed.
Key Factors:
- â–¸Understanding the specific abnormal finding
- â–¸Knowing when to use these codes versus a specific diagnosis code
- â–¸Keeping up with updates and changes to the ICD-10 guidelines
- â–¸Determining the correct code based on the laboratory test performed
Specialty Focus
R80-R89 codes are commonly used in general practice, internal medicine, and hematology. They are used when abnormal blood findings are discovered during routine check-ups, preliminary testing, or in the process of diagnosing a condition.
