Diagnosis Coding for Mental Health in ICD-10-CM


By Holly Cassano, CPC

In my article earlier this week, I illustrated some of the statistics on people who suffer from a mental illness/disorder in this country, as details emerged in the news that the perpetrator of the Newtown school shooting suffered from a form of Asperger’s syndrome, to bring further awareness to the seemingly epidemic level that these conditions currently represent.

Asperger’s syndrome, which is classified in ICD-10-CM as a schizoid personality disorder, is represented by ICD-10-CM, F60.1 – Schizoid personality disorder/Asperger’s syndrome. With more than 26% of the population in the U.S. over the age of 18 affected by a form of mental disorder, about 6% can be categorized with a major illness, such as Asperger’s.

One of the changes for ICD-10-CM is the developers wrote specific guidelines to allow for further specificity for mental disorders. Currently, in ICD-9-CM, there are basically none to instruct providers and coders for better reporting, which can make coding and billing for these services a reimbursement nightmare for many practices, as most insurers have specific guidelines for reporting.

ICD-10-CM will allow for more effective documentation of these illnesses/disorders, which will improve reimbursement back to the practice. As a reminder, providers and billing/coding professionals should adhere to the golden rules of proper medical record documentation:

  • Complete and legible
  • Documentation of each encounter
  • Reason for encounter
  • Examination findings
  • Diagnostic test results
  • Assessment
  • Clinical impression/diagnosis
  • Plan for care
  • Problem list
  • Health risk factors identified
  • All CPT And ICD-9-CM codes reported must be supported by documentation in the medical record

I have illustrated what some of the codes for behavioral and mental disorders will look like in ICD-10-CM. As you can see from the list below, it is a much more expansive list than what we currently utilize in ICD-9-CM. When ICD-10-CM goes into effect on Oct. 1, 2014, billing and coding professionals will have better reporting capabilities, which overall will help improve outcomes from studies that are done from tracking codes such as these and aid in providing better care for those affected by these illnesses/disorders.

Final Thoughts
Again I will reiterate the importance of accurate code reporting in order to ensure proper reimbursement from Payers and to keep your accounts receivable in the black and maintain positive cash flow to the practice. It is also vital to ensure accurate code reporting so that Payers will have a clear picture of a member’s mental health profile and be able to provide better benefits and treatment overall.

I refer again to the National Institute of Mental Health (NIMH), which provides an extensive resource on such statistics and can be accessed for more information by clicking here.

Happy Coding!
