Update on Adoption of ICD-10

On April 1, 2014, President Obama signed into law a bill that will delay the adoption of ICD-10 by Centers for Medicare & Medicaid Services (CMS) for one year.  All covered entities under the Health Insurance Portability Accountability Act (HIPAA) will be required to transition from the ICD-9 diagnostic coding set to the ICD-10 diagnostic coding set on October 1, 2015.  In anticipation of this migration, the Commission adopted a change to the billing requirements found in IDAPA Whenever possible, providers shall bill using the diagnostic and procedure coding set required by Centers for Medicare & Medicaid Services.  All Idaho workers’ compensation payers will now have an additional year to take the proper steps to ensure the ability to promptly pay medical bills received from providers with the new ICD-10 diagnostic and procedure coding sets.  Further information regarding ICD-10 may be obtained from the Centers for Medicare & Medicaid Services, or by contacting Patti Vaughn at the Industrial Commission,  (208) 334-6084.

Balance Billing

Idaho is a zero-deductible state for workers' compensation medical charges. No portion of the unpaid medical bill is to be paid by the injured worker on claims accepted by the surety.

Medical Records

As noted in IDAPA, Providers shall submit written medical reports for each medical visit to the Payor. Payers and Providers may contract with one another to identify specific records that will be provided in support of billings. The Provider shall also submit the same written medical reports to the Claimant upon request. These reports shall be submitted within fourteen (14) days following each evaluation, examination and/or treatment. The first copy of any such reports shall be provided to the Payor and the Claimant or Claimant's Counsel at no charge. If duplicate copies of reports already provided are requested by either the Payor or the Claimant, the Provider may charge the requesting party a reasonable charge to provide the additional reports.

The first copy of any such reports shall be provided to the Payor and the Claimant at no charge. If duplicate copies of reports already provided are requested by either the Payor or the Claimant, the Provider may charge the requesting party a reasonable charge to provide the additional reports.

This means the medical provider must give one free copy to one of each of the following:

  • Employer or insurance company
  • Claimant (patient) or claimant’s attorney
  • The Idaho Industrial Commission

Dispute Resolution (top)


Change to Application of 30% Penalty In Medical Fee Disputes

For all Motions filed on or after October 1, 2014, unless the payer demonstrates, by timely response to the provider’s Motion, that the payer’s previous payment is adequate, the penalty will now be applied to the underpayment owed at the time the Motion was filed.  Payments issued after the filing of the Motion may be deducted from the ordered amount, but will not reduce the penalty.
