ICD-10 is simplified as compared to ICD-9
In ICD-10 we need to give only one code for Type 2 diabetes with diabetic gastroparesis (complication affecting the body system),
Read the ICD-10 guideline
4. Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00-E89)
a. Diabetes mellitus
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.
So code only one code
See:
Alphabetic Index
Diabetes, diabetic (mellitus) (sugar) E11.9
- with
- - gastroparesis E11.43
Gastroparesis K31.84
- diabetic —see Diabetes, by type, with gastroparesis
Tabular Index
E11.43
Type 2 diabetes mellitus with diabetic autonomic (poly)neuropathy
Type 2 diabetes mellitus with diabetic gastroparesis
Guidelines of coding combination code.
Section I:
B. General Coding Guidelines
9.Assign only the combination code when that code fully identifies the diagnostic conditions involved or when the Alphabetic Index so directs. Multiple coding should not be used when the classification provides a combination code that clearly identifies all of the elements documented in the diagnosis. When the combination code lacks necessary specificity in describing the manifestation or complication, an additional code should be used as a secondary code.
Here in the code E11.43 the second line in tabular index, it indicates : "Type 2 diabetes mellitus with diabetic gastroparesis" which includes both diabetes and gastroparesis, so no need to give additional gastroparesis code.
