Diabetes can be a challenge for coders. ICD-10-CM does assume the link between diabetes and multiple common conditions. In the index of ICD-10-CM you will see these assumed conditions.
Here’s a list of the associated diabetic conditions where the link is assumed in ICD-10-CM:
- amyotrophy
- arthropathy NEC
- autonomic (poly) neuropathy
- cataract
- Charcot’s joints
- chronic kidney disease
- circulatory complication NEC
- coma due to hyperosmolarity, hypoglycemia, ketoacidosis
- complication specified NEC
- dermatitis
- foot ulcer
- gangrene
- gastroparalysis
- gastroparesis
- glomerulonephrosis, intracapillary
- glomerulosclerosis, intercapillary
- hyperglycemia
- hyperosmolarity with coma
- hypoglycemia with coma
- ketoacidosis with coma
- kidney complications NEC
- Kimmelsteil-Wilson disease
- loss of protective sensation(LOPS) – see Diabetes, by type, with neuropathy
- mononeuropathy
- myasthenia
- necrobiosis lipoidica
- nephropathy
- neuralgia
- neurologic complication NEC
- neuropathic arthropathy
- neuropathy
- ophthalmic complication NEC
- oral complication NEC
- osteomyelitis
- periodontal disease
- peripheral angiopathy with gangrene
- polyneuropathy
- renal complication NEC
- renal tubular degeneration
- retinopathy with macular edema or resolved following treatment
- retinopathy nonproliferative with macular edema (mild, moderate, or severe)
- retinopathy proliferative with combined traction retinal detachment and rhegmatogenous retinal detachment, macular edema, stable proliferative diabetic retinopathy, traction retinal detachment involving the macula, and traction retinal detachment not involving the macula
- skin complication NEC
- skin ulcer NEC
If the MD documents another etiology for the condition DO NOT code to a diabetic complication or assume the link with diabetes.
If unsure about a specific condition being due to or “with” diabetes, coders can look the condition up in the ICD-10-CM Index. All the above associated diabetic conditions will have an entry for “diabetic.” If you search those terms.
Example 1: Patient has documented diabetes as well as a diagnosis of amyotrophy. neuralgia. Under the term for diabetes, amyotrophy is listed under the “with” subterm. Now look under the main term amyotrophy and there is a subterm for diabetic.
Example 2: Patient has documented hypertension and diabetes. This would not be an assumed link using the term “with.” Hypertension is a circulatory issue but the entry for circulatory complication also includes NEC. This means that the condition is not elsewhere classified within ICD-10 which is not the case for hypertension.
