Code Classification

  • Endocrine, nutritional and metabolic diseases

    • Diabetes mellitus

      • Type 2 diabetes mellitus
        (E11)

E11.33 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of type 2 diabetes mellitus with moderate nonproliferative diabetic retinopathy. The code is not specific and is NOT valid for the year 2024 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.

The code is commonly used in family practice medical specialties to specify clinical concepts such as diabetes mellitus with complications type 2.

Specific Coding Applicable to Type 2 diabetes w moderate nonprlf diabetic retinopathy

Non-specific codes like E11.33 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for type 2 diabetes w moderate nonprlf diabetic retinopathy:

  • E11.331 for Type 2 diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema - NON-BILLABLE CODE

  • Use E11.3311 for right eye - BILLABLE CODE

  • Use E11.3312 for left eye - BILLABLE CODE

  • Use E11.3313 for bilateral - BILLABLE CODE

  • Use E11.3319 for unspecified eye - BILLABLE CODE

  • E11.339 for Type 2 diabetes mellitus with moderate nonproliferative diabetic retinopathy without macular edema - NON-BILLABLE CODE

  • Use E11.3391 for right eye - BILLABLE CODE

  • Use E11.3392 for left eye - BILLABLE CODE

  • Use E11.3393 for bilateral - BILLABLE CODE

  • Use E11.3399 for unspecified eye - BILLABLE CODE

Coding Guidelines

The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08 - E13 as needed to identify all of the associated conditions that the patient has.

If the type of diabetes mellitus is not documented in the medical record the default is E11.-, Type 2 diabetes mellitus.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


7th Character Note

7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
  • One of the following 7th characters is to be assigned to codes in subcategory E11.33 to designate laterality of the disease:

7th Character

7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
  • 1 - right eye
  • 2 - left eye
  • 3 - bilateral
  • 9 - unspecified eye

Patient Education


Type 2 diabetes

Type 2 diabetes is a disorder characterized by abnormally high levels of blood glucose, also called blood sugar. In this form of diabetes, the body stops using and making insulin properly. Insulin is a hormone produced in the pancreas that helps regulate blood glucose levels. Specifically, insulin controls how much glucose (a type of sugar) is passed from the blood into cells, where it is used as an energy source. When blood glucose levels are high (such as after a meal), the pancreas releases insulin to move the excess glucose into cells, which reduces the amount of glucose in the blood.

Most people who develop type 2 diabetes first have insulin resistance, a condition in which the body's cells use insulin less efficiently than normal. As insulin resistance develops, more and more insulin is needed to keep blood glucose levels in the normal range. To keep up with the increasing need, insulin-producing cells in the pancreas (called beta cells) make larger amounts of insulin. Over time, the beta cells become less able to respond to blood glucose changes, leading to an insulin shortage that prevents the body from reducing blood glucose levels effectively. Most people have some insulin resistance as they age, but inadequate exercise and excessive weight gain make it worse, greatly increasing the likelihood of developing type 2 diabetes.

Type 2 diabetes can occur at any age, but it most commonly begins in middle age or later. Signs and symptoms develop slowly over years. They include frequent urination (polyuria), excessive thirst (polydipsia), fatigue, blurred vision, tingling or loss of feeling in the hands and feet (diabetic neuropathy), sores that do not heal well, and weight loss. If blood glucose levels are not controlled through medication or diet, type 2 diabetes can cause long-lasting (chronic) health problems including heart disease and stroke; nerve damage; and damage to the kidneys, eyes, and other parts of the body.
