- Taxonomy Description
- Doctors of optometry (ODs) are the primary health care professionals for the eye. Optometrists examine, diagnose, treat, and manage diseases, injuries, and disorders of the visual system, the eye, and associated structures as well as identify related systemic conditions affecting the eye. An optometrist has completed pre-professional undergraduate education in a college or university and four years of professional education at a college of optometry, leading to the doctor of optometry (O.D.) degree. Some optometrists complete an optional residency in a specific area of practice. Optometrists are eye health care professionals state-licensed to diagnose and treat diseases and disorders of the eye and visual system.

NPI Validation Check Digit Calculation
The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.
| Start with the original NPI number, the last digit is the check digit and is not used in the calculation. | |||||||||
| 1 | 8 | 5 | 1 | 4 | 6 | 8 | 1 | 1 | 0 |
| Step 1: Double the value of the alternate digits, beginning with the rightmost digit. | |||||||||
| 2 | 8 | 10 | 1 | 8 | 6 | 16 | 1 | 2 | |
| Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24. | |||||||||
| 2 + 8 + 1 + 0 + 1 + 8 + 6 + 1 + 6 + 1 + 2 + 24 = 60 | |||||||||
| Step 3: because the number obtained in step 2 ends in zero, the check digit is zero. | |||||||||
| 0 | |||||||||
The NPI number 1851468110 is valid because the calculated check digit 0 using the Luhn validation algorithm matches the last digit of the original NPI number.
