I10 – Hypertension:
Many of the changes to I10 (hypertension) were due to not following the official coding guidelines when the patient also has heart disease and/or kidney disease. ICD-10-CM assumes a relationship between hypertension when the patient has heart disease or kidney disease. The two conditions are linked by the term “with” in the Alphabetic index. These conditions should be coded as related unless the provider specifically states that they are not related or documents a different cause for the kidney or heart disease.

E11.9 – Type 2 Diabetes Without Complications:
As with hypertension changes, many of the changes to E11.9 (Type 2 Diabetes w/o complication) were related to conditions that are presumed to be related to diabetes. These fall under the “with” guidelines. Review the Alphabetic index for any condition that is presumed to be related to diabetes (chronic kidney disease, foot ulcer, gangrene, etc.).

K29.60 – Other Gastritis Without Bleeding:
Changes to K29.60 (Gastritis w/o Bleeding) were also related to the “with” guideline. This is a change from previous guidance given for ICD-9-CM coding. Prior to the “with” guideline for ICD-10-CM coding, it was suggested to query the provider to confirm the cause of the bleeding if the relationship was not stated in the record. Now, since the tabular index lists Gastritis “with” bleeding it would be appropriate to code gastritis with bleeding, unless the provider states the bleeding was not due to the gastritis. In addition to the “with” guideline, remember there are codes for the specific type of gastritis. Make sure to code the most specific code if appropriate.

R13.19 – Other Dysphagia:
Specificity resulted in many of the changes to R13.19 (Other Dysphagia). In reviewing the accounts, documentation supported the specific type of dysphagia (functional, hysterical, neurogenic, etc.) or that dysphagia was a result (following) another condition (CVA, intracerebral hemorrhage, etc.). Coders must always review the entire encounter to assure they are selecting the most specific code. If the dysphagia is following a specific condition, such as a CVA, make sure to select the appropriate code to reflect this condition.

I25.10 – Atherosclerotic Heart Disease of Native Coronary Artery (CAD) Without Angina Pectoris:
Changes to this code were a result of documentation that the patient had angina. Under ICD-9-CM angina was coded separately from coronary artery disease (CAD). Under ICD-10-CM there is a code for CAD without angina, and codes to reflect if CAD is with angina and the type of angina. Make sure to review the index and select the codes that are appropriate to reflect if CAD is with or without angina.
