Coding & Billing

Specialty Lens Coding for Insurance Reimbursement

Insurance coding is complicated and can be confusing and extremely time consuming. Here are a few suggestions to help:

1. Be sure your office has the current code books:

  • Diagnosis Codes

1 ICD-9-CM 2012ICD-9-CM

The current ICDN code book is dated 2012 and can be used until the end of September, but on October 1, 2015 the new ICD-10 codes go into effect and must be used. Be proactive and ensure the billing software your office uses will be able to incorporate these new codes.

2 icd-10-2014ICD-10-CM *MUST use after October 1, 2015*

There will be many changes, so   be sure your current office software will be compatible
