An ICD-10-CM Definition for Eye Care Professionals

On June 21, 2019, the Centers for Medicare & Medicaid Services (CMS) and the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics (NCHS) released the International Classification of Diseases, Tenth Edition (ICD-10-CM) code changes for 2020.

The World Health Organization (WHO) owns, develops and publishes ICD codes. The 2020 code changes are the fourth mandated update to ICD-10-CM codes since the switch from ICD-9 to ICD-10 went live on October 1, 2015.

ICD-10-CM is a medical code that describes the condition and diagnoses of patients, whereas the ICD-10-PCS code describes inpatient procedures. A diagnosis code tells the insurance payer why you performed the service.

Prepare Your Staff for Updated ICD-10-CM Codes

Preparation is a critical step in your action plan. The following pro tips will help your staff prepare for upcoming ICD-10-CM code updates so your practice is set up for success.

  1. Review and become familiar with the new codes for optometric billing (download our 2020 ICD-10-CM codes update guide). For all claims that have a service date of September 30, 2019, or earlier, you must use the 2019 codes or your claim will get rejected or denied.

  2. Add new codes and remove the old codes in your “favorites” list (optional).
    Most eye care EHR systems include default plans and assessments that are preloaded. Review and modify your plans, assessments, and outbound documents that were mapped from the old 2019 codes to new 2020 codes.

  3. Review and update all “code rules” you created in your EHR and practice management software that are affected by the new and deleted 2020 codes.

  4. Be careful when using “copy from previous” as many optometry software systems will copy over removed codes. Check that the primary ICD-10 codes match the primary chief complaint and reason for the visit in the exam note.

  5. Contact your optometry and ophthalmology industry associations for specific coding changes and ICD-10 coding resources. Listed below are a few resources to get you started.
