I-10 Corner: Chapter 5 – Mental, Behavioral, and Neurodevelopmental Disorders (F01-F99)

on Tuesday, 08 July 2014. All News Items | Documentation | Coding

Our next topic for the I-10 corner is the mental health chapter, Mental, Behavioral, and Neurodevelopmental Disorders. Chapter 5 is another example of the massive expansion of codes in ICD-10. I have highlighted some changes and included tips that I think are important to know for coding these conditions.

See below how the codes in this chapter are no longer grouped by psychotic, non-psychotic disorders, or mental retardation.

NOTE FROM ICD-10-CM CODER TRAINING MANUAL 2014

I-9

I-10

Tobacco Use Disorder (305.1) Exposure to environmental tobacco smoke (Z77.22)
  Exposure to tobacco smoke in the perinatal period (P96.81)
History of Tobacco Use (V15.82) History of tobacco use (Z87.91)
  Occupational exposure to environmental tobacco smoke (Z57.31)
  Tobacco dependence (F17.-)
  Tobacco use (Z72.0)
Many title changes for categories and subcategories were made in Chapter 5. Such as:
Bipolar 1 Disorder, Single Manic Episode (296.0x) = Manic Episode (F30.xx)

Many changes were made due to outdated terminology. Examples can be seen in the accompanying table.

 

 

DID YOU KNOW?

DRG Shift

The CMS ICD-10 website contains information on the ICD-10 MS-DRG Conversion Project. An article from CMS, “Estimating the Impact of the Transition to ICD-10 on Medicare Inpatient Hospital Payments”, lists the top 10 MS-DRGs that shift to another DRG when re-coded with ICD-10. DRG 885, Psychoses is on that list. Currently, ICD-9 cases that have 296.20, Major Depression, Single Episode, Unspecified sequenced as the principal diagnosis will group to DRG 885, Psychoses. Under ICD-10, this same diagnosis is assigned to F32.9 (also includes Depression NOS) which groups the case to DRG 881, Depressive Neuroses, a lower-weighted DRG. Interestingly, many hospitals in Alabama have DRG 885 listed in their top 10 diagnoses each year. It would be a good idea to see how this change will impact your facility.

A large classification change was made to the drug and alcohol abuse/dependence codes.

  • There are codes to denote alcohol and drug “use”.
  • No longer identify “Continuous” and “Episodic” in I-10
  • Can code Blood Alcohol Levels as an additional code, if applicable:
    Y90.0, Evidence of alcohol involvement determined by blood alcohol level

Chapter 5 Guidelines

  • Physician documentation of a history of drug or alcohol dependence is coded as “in remission”.
  • For psychoactive substance use, abuse and dependence:
TIP

When documentation refers to use, abuse and dependence of the same substance only assign one code based on following hierarchy:

  • If use and abuse documented, assign abuse code
  • If abuse and dependence documented, assign dependence code
  • If use, abuse and dependence are documented, assign dependence code
  • If use and dependence are documented, assign dependence code

 

The codes in Chapter 5 parallel the codes in DSM-IV TR (Diagnostic and Statistical Manual of Mental Disorders-4 Text Revision) in most cases….from the ICD-10-CM Coder Training Manual, 2014 Instructor’s Edition. Psychiatrists tend to document these conditions as they are listed in the codebooks, which can make mental health coding a little easier. In addition, I hope all of the information provided to you in the I-10 Corner has helped make your job a little easier.
