Range Overview

high priority

The E08-E13 range in ICD-10 is dedicated to Diabetes Mellitus, a group of metabolic disorders characterized by high blood sugar levels over a prolonged period. This range covers all types of diabetes, including Type 1, Type 2, gestational, and drug-induced diabetes. It also includes codes for complications and manifestations associated with diabetes, such as diabetic neuropathy, nephropathy, retinopathy, and others.

Key Usage Points:

  • E08-E13 codes are used to specify the type of diabetes a patient has.
  • These codes also indicate whether the diabetes is controlled or uncontrolled.
  • Complications and manifestations of diabetes are coded within this range.
  • Combination codes are used to indicate diabetes with associated conditions.
  • The fifth character in the code often indicates the type and control status of diabetes.

Coding Guidelines

When to Use:

  • When a patient is diagnosed with any type of diabetes.
  • When a patient with diabetes presents with related complications.
  • When a patient's diabetes is not well controlled.
  • When a patient has gestational diabetes.
  • When a patient's diabetes is induced by drugs.

When NOT to Use:

  • When a patient has prediabetes or impaired glucose tolerance.
  • When a patient has secondary diabetes due to another condition.
  • When a patient's hyperglycemia is temporary.
  • When a patient has neonatal diabetes.

Code Exclusions

Always verify exclusions with the latest ICD-10-CM official guidelines.

Documentation Requirements

Proper documentation for diabetes coding in the E08-E13 range requires specific clinical information and supporting evidence. This includes the type of diabetes, control status, and any associated complications or manifestations.

Clinical Information:

  • Type of diabetes (Type 1, Type 2, gestational, etc.)
  • Control status of diabetes (controlled, uncontrolled)
  • Presence of any diabetes-related complications
  • Specific body systems affected by diabetes
  • Cause of diabetes, if drug-induced or due to underlying condition

Supporting Evidence:

  • Lab results confirming diagnosis
  • Medical history and physical examination notes
  • Medication records, if diabetes is drug-induced
  • Imaging studies, if applicable
Good Documentation Example:

Patient diagnosed with Type 2 diabetes, uncontrolled, with diabetic peripheral neuropathy. Lab results confirm high blood glucose levels. Patient is on insulin therapy.

Poor Documentation Example:

Patient has diabetes.

Common Documentation Errors:

  • Not specifying the type of diabetes
  • Failing to indicate control status
  • Not documenting associated complications
  • Using incorrect codes for excluded conditions

Coding Complexity

Medium
Complexity Rating

Coding for diabetes in the E08-E13 range can be complex due to the need to accurately represent the type and control status of diabetes, as well as any associated complications. Additionally, guidelines and codes may change, requiring coders to stay updated.

Key Factors:
  • Determining the type and control status of diabetes
  • Identifying and coding for associated complications
  • Using combination codes correctly
  • Staying updated on changing guidelines and code updates

Specialty Focus

The E08-E13 range is primarily used by endocrinologists, primary care physicians, and obstetricians. However, any specialty dealing with patients with diabetes may use these codes.

Primary Specialties:
Endocrinology
40%
Primary Care
35%
Obstetrics
25%
Clinical Scenarios:
  • A patient with Type 1 diabetes presenting with diabetic ketoacidosis.
  • A patient with Type 2 diabetes and peripheral neuropathy.
  • A pregnant patient diagnosed with gestational diabetes.
  • A patient with drug-induced diabetes due to steroid therapy.
  • A patient with uncontrolled diabetes presenting with hyperglycemia.

Frequently Asked Questions

How do I code for a patient with Type 2 diabetes and diabetic retinopathy?

You would use a combination code from the E11 (Type 2 diabetes) subcategory that includes diabetic retinopathy. For example, E11.319 for 'Type 2 diabetes mellitus with unspecified diabetic retinopathy without macular edema'.
