    ICD-10 Coding Took Effect Oct. 1, 2015


    The transition to the new ICD-10 coding system took effect on Oct. 1, 2015. Do you need some guidance? TMA has you covered with a variety of tools and resources to get you up to speed. 

    Remember: ICD-10 is service-date driven, so if you file a claim on or after Oct. 1 for services you provided Sept. 30 or earlier, you must file the claim using ICD-9 codes. If you run into problems submitting claims, send a report to TMA's Hassle Factor Log or email PaymentAdvocacy@texmed.org. TMA staff will be monitoring the reports and contacting health plans, Medicare, or Medicaid as necessary. 

    Payers expect they'll receive late filings and adjustments of pre-Oct. 1 claims and will continue to accept ICD-9 codes for those claims. Submit adjusted claims using the code set with which you originally filed the claim. Never combine ICD-9 and ICD-10 codes on one claim.
