Is it automatically assumed that when a provider states the patient has essential hypertension and a certain stage of CKD that you code the hypertension as either I12.9 or I12.0?
Where my mind twists this guideline is when the physician states that the CKD is due to something else other than HTN, but does not clearly state that the CKD and HTN are not linked, do you still have to assume cause and effect between the HTN and CKD?The ICD-10-CM coding guidelines clearly state to assume a causal relationship between HTN and CKD because they are linked with the term 'with' in the alphabetical index. Please refer to section 1.C.9.a.2 in the guidelines. The only time you would not link them is if the provider stated the two conditions are not linked, otherwise they are and I12.x is the correct code range to use with an additional code for the stage of CKD.
You are overthinking this. If the provider states that CKD is due to something other than HTN then you have sufficient documentation to NOT use I12 codes. By saying it is due to something else they are clearly stating they are not linked.Where my mind twists this guideline is when the physician states that the CKD is due to something else other than HTN, but does not clearly state that the CKD and HTN are not linked, do you still have to assume cause and effect between the HTN and CKD?
