About coding Fahr Volhard disease

The ICD-10-CM code for Fahr Volhard disease is I12 (Hypertensive chronic kidney disease).

To report this condition, pick the subcode that matches the documentation: I12.0 (with stage 5 chronic kidney disease or end stage renal disease) and I12.9 (with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease).

Don't report I12 together with the conditions in its Excludes1 note: hypertension due to kidney disease (I15.0, I15.1), renovascular hypertension (I15.0) and secondary hypertension (I15.-).

The conditions in its Excludes2 note aren't part of I12, but may be coded alongside it if the patient has both: acute kidney failure (N17.-).

Don't confuse with (Excludes1 for I12)

  • hypertension due to kidney disease (I15.0, I15.1)
  • renovascular hypertension (I15.0)
  • secondary hypertension (I15.-)
