Not Valid for Submission
R79 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other abnormal findings of blood chemistry. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding for Other abnormal findings of blood chemistry
Header codes like R79 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other abnormal findings of blood chemistry:
- R79.0 - Abnormal level of blood mineral
- R79.1 - Abnormal coagulation profile
- R79.8 - Other specified abnormal findings of blood chemistry
- R79.81 - Abnormal blood-gas level
- R79.82 - Elevated C-reactive protein (CRP)
- R79.89 - Other specified abnormal findings of blood chemistry
- R79.9 - Abnormal finding of blood chemistry, unspecified
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code R79:
Use Additional CodeUse Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify any retained foreign body, if applicable Z18
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- asymptomatic hyperuricemia E79.0
- hyperglycemia NOS R73.9
- hypoglycemia NOS E16.2
- neonatal hypoglycemia P70.3 P70.4
- specific findings indicating disorder of amino-acid metabolism E70 E72
- specific findings indicating disorder of carbohydrate metabolism E73 E74
- specific findings indicating disorder of lipid metabolism E75
Information for Patients
Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs. White blood cells (WBC) fight infection and are part of your immune system. Platelets help blood to clot when you have a cut or wound. Bone marrow, the spongy material inside your bones, makes new blood cells. Blood cells constantly die and your body makes new ones. Red blood cells live about 120 days, and platelets live about 6 days. Some white blood cells live less than a day, but others live much longer.
There are four blood types: A, B, AB, or O. Also, blood is either Rh-positive or Rh-negative. So if you have type A blood, it's either A positive or A negative. Which type you are is important if you need a blood transfusion. And your Rh factor could be important if you become pregnant - an incompatibility between your type and the baby's could create problems.
Blood tests such as blood count tests help doctors check for certain diseases and conditions. They also help check the function of your organs and show how well treatments are working. Problems with your blood may include bleeding disorders, excessive clotting and platelet disorders. If you lose too much blood, you may need a transfusion.
