Hyperglycemia ICD-10-CM Codes

What ICD-10 Codes are Used for Hyperglycemia

Hyperglycemia is a condition in which the blood sugar level is too high. It is a common symptom of diabetes mellitus, but it can also be caused by other conditions, such as Cushing's syndrome, pancreatitis, and certain medications.

The following are 10 commonly used hyperglycemia ICD Codes:

R73.0 Abnormal glucose

This code reports an abnormal blood sugar level not specifically classified elsewhere.

R73.01 Impaired fasting glucose

This code reports a blood sugar level higher than normal but not high enough to be diagnosed as diabetes mellitus.

R73.02 Impaired glucose tolerance (oral)

This code reports a blood sugar level higher than normal after a glucose tolerance test.

R73.03 Prediabetes

This code reports a condition in which the blood sugar level is higher than normal but not high enough to be diagnosed as diabetes mellitus.

R73.9 Hyperglycemia, unspecified

This code is used to report hyperglycemia that is not specifically classified elsewhere.

E08.00 Diabetes mellitus due to underlying condition with hyperosmolarity without nonketotic hyperglycemic-hyperosmolar coma (NKHHC)

This code is used to report diabetes mellitus caused by an underlying condition, such as Cushing's syndrome or pancreatitis, and is associated with hyperosmolarity but not with NKHHC.

‍E08.01 Diabetes mellitus due to underlying condition with NKHHC

This code is used to report diabetes mellitus that is caused by an underlying condition, such as Cushing's syndrome or pancreatitis, and is associated with NKHHC.

E09.65 Drug or chemical-induced diabetes mellitus with hyperglycemia

This code reports diabetes mellitus caused by a drug or chemical, such as steroids or pentamidine, and is associated with hyperglycemia.

E09.69 Drug or chemical-induced diabetes mellitus with other specified complication

This code reports diabetes mellitus caused by a drug or chemical, such as steroids or pentamidine, and is associated with a complication other than hyperglycemia.

Which Hyperglycemia  ICD codes are Billable: 

R73.0 Abnormal glucose:

Yes, this code is billable because it is a specific diagnosis code used to report an abnormal blood sugar level.

R73.01 Impaired fasting glucose:

Yes, this code is billable because it is a specific diagnosis code used to report a blood sugar level higher than normal but not high enough to be diagnosed as diabetes mellitus.

R73.02 Impaired glucose tolerance (oral):

Yes, this code is billable because it is a specific diagnosis code used to report a blood sugar level higher than normal after a glucose tolerance test.

R73.9 Hyperglycemia, unspecified:

Yes, this code is billable because it is a general diagnosis code used to report hyperglycemia that is not specifically classified elsewhere.

E08.00 Diabetes mellitus due to underlying condition with hyperosmolarity without nonketotic hyperglycemic-hyperosmolar coma (NKHHC):

Yes, this code is billable because it is a specific diagnosis code that is used to report diabetes mellitus that is caused by an underlying condition and is associated with hyperosmolarity but not with NKHHC.

E09.65 Drug or chemical-induced diabetes mellitus with hyperglycemia:

Yes, this code is billable because it is a specific diagnosis code that is used to report diabetes mellitus that is caused by a drug or chemical and is associated with hyperglycemia.

R73.9 Hyperglycemia, unspecified:

This code is not billable if used as the only diagnosis code on a claim. This code can only be used as a secondary diagnosis code.

E08.9 Diabetes mellitus without complications

This code is not billable because it does not specify the type of diabetes mellitus.

E09.9 Drug or chemical-induced diabetes mellitus without complication

This code is not billable because it does not specify the drug or chemical that caused diabetes mellitus.

Clinical Information

• Hyperglycemia is a condition in which the blood sugar level is too high.
• Hyperglycemia can be caused by diabetes mellitus, Cushing's syndrome, pancreatitis, and certain medications.
• Symptoms of hyperglycemia may include increased thirst, frequent urination, blurred vision, fatigue, and weight loss.
• Hyperglycemia can be diagnosed with a blood test.
• Treatment for hyperglycemia depends on the underlying cause. For diabetes mellitus, treatment typically includes diet, exercise, and medication.
• Complications of hyperglycemia can include diabetic ketoacidosis, hyperosmolar hyperglycemic state, and diabetic retinopathy.
• Normal blood sugar levels vary depending on the time of day and the type of test. However, a blood sugar below 100 mg/dL is generally considered normal.
• Prediabetes is when the blood sugar level is higher than normal but not high enough to be diagnosed as diabetes mellitus. People with prediabetes are at an increased risk of developing diabetes mellitus.
• Diabetes mellitus is a chronic condition that affects how the body metabolizes glucose. There are two main types of diabetes mellitus: type 1 and type 2.
• Type 1 diabetes is an autoimmune disease that causes the body to attack the cells in the pancreas that produce insulin. Insulin is a hormone that helps the body use glucose for energy.
• Type 2 diabetes is a condition in which the body becomes resistant to insulin. This means that the body's cells do not respond to insulin as well as they should.

Synonyms Include:

• High blood sugar
• Hyperglycaemia
• High glucose
• Diabetic condition
• Increased blood glucose
