Diabetes Mellitus ICD 9 vs ICD 10 vs 10-cm Coding

The major difference in the coding of diabetes mellitus as compared to the current ICD-9 system will first be experienced in the classification of the disease. The current system only classifies the condition as either controlled or uncontrolled. ICD-10 will classify Diabetes mellitus as either inadequately controlled, out of control or poorly controlled based on the type of hyperglycemia. ICD-10-CM is a combination of codes that will be used to specify the type of diabetes mellitus, body system affected and the complications that the body is experiencing.

ICD 10-CM Codes for Diabetes Mellitus

For Medial Billing and Coding purpose, Diabetes mellitus will be covered by 5 major ICD codes namely:
  • E08 Diabetes Mellitus due to Underlying Condition
  • E09 Drug or Chemical Induced Diabetes Mellitus
  • E10 Type 1 Diabetes Mellitus
  • E11 Type 2 Diabetes Mellitus
  • E13 Other Specified Diabetes Mellitus
Diabetes Mellitus ICD9 and ICD10 Coding Difference
ICD-9-CM codes for diabetes mellitus have the deficiency of only identifying the complication/manifestation of the condition. This is to change as ICD-10-CM will identify the type of diabetes as well as the complication/manifestation. When differentiating between the two types of diabetes ICD-9-CM uses Roman numerals while ICD-10-CM uses Arabic numbers.

ICD-10-CM code E11.40 will be used to specify diabetes mellitus type 2 with diabetic neuropathy while E11.65 ICD-10-CM code on its part will be used to specify diabetes type 2 with hyperglycemia.

ICD 10-cm Codes for Diabetes Neuropathy

ICD 10-cm Code for Genetic Diabetes
E13 is an ICD-10-CM code that will be used to specify diabetes mellitus caused by genetic defects of beta-cell-function or due to genetic defects in the insulin action. The same code will also be used for Postprocedurial diabetes mellitus and secondary diabetes mellitus NEC.

ICD 10-cm Diabetic Retinopathy
