Mad cow disease anyone?

You’ve probably heard that you need to beef up your clinical knowledge for ICD-10-CM and ICD-10-PCS coding. And you’re probably wondering when you have time to do that.
We’re here to help. We’ve researched 140 clinical conditions and collected them in JustCoding’s Clinical Conditions Encyclopedia. Each entry includes clinical information, such as signs and symptoms, types or stages, and treatment, along with coding and documentation for both ICD-9-CM and ICD-10-CM.
Mad cow disease, more properly called Creutzfeldt-Jakob disease (CJD), is one of the conditions the encyclopedia covers. CJD is divided into three major categories:
  • Sporadic CJD
  • Hereditary CJD
  • Acquired CJD
On October 1, 2008, the Cooperating Parties revised and expanded the ICD-9-CM codes for CJD to include:
  • Variant Creutzfeldt-Jakob disease: Report code 046.11
  • Other and unspecified Creutzfeldt-Jakob disease: Report code 046.19
  • Dementia in conditions classified elsewhere without behavioral disturbance: Report code 294.10
  • Dementia in conditions classified elsewhere with behavioral disturbance: Report code 294.11
The revised code description for code 046 includes slow virus infections and prion diseases of the central nervous system. The fifth digit represents the form of the disease. Currently, only variant CJD has a fifth
digit of a 1. Report code 046.19 for all other forms.
When a patient develops dementia with or without behavioral disturbance, report an additional code to represent the dementia.
When we get to ICD-10-CM, our coding will look like this:
  • Creutzfeldt-Jakob disease, unspecified, or Jakob-Creutzfeldt disease, unspecified: A81.00
  • Variant Creutzfeldt-Jakob disease: A81.01
  • Other Creutzfeldt-Jakob disease including familial Creutzfeldt-Jakob disease, iatrogenic Creutzfeldt-Jakob disease, sporadic Creutzfeldt-Jakob disease, and subacute spongiform encephalopathy (with dementia): A81.09
Category A81 (atypical virus infections of central nervous system) still includes diseases of the central nervous system caused by prions.
And we will still use an additional code to identify:
  • Dementia with behavioral disturbance (F02.81)
  • Dementia without behavioral disturbance (F02.80)
While you’re unlikely to see a large number CJD diagnoses, you probably code for patients with anemia, hypertension, heart failure, migraine, stroke, and syncope. All of those conditions are part of the encyclopedia as well.
You’ll also find some less common conditions such as hungry bone syndrome, blue diaper syndrome, and kabuki syndrome.
