Question 1

What does the Code Validator do?

Accepted Answer

The validator checks if CPT and ICD-10 codes are valid, active, and properly formatted. It flags invalid codes, inactive codes, and code errors. It provides suggestions for corrections.

Question 2

What is the difference between invalid and inactive codes?

Accepted Answer

Invalid codes don't exist in the official CPT/ICD-10 system. Inactive codes existed but were retired/deleted. Both should not be billed. The validator explains which issue you have and suggests alternatives.

Question 3

Can I use an inactive code?

Accepted Answer

No. Inactive codes cause claim rejections. Use the suggested replacement code instead. Insurance companies automatically reject inactive codes, so they must be replaced before billing.

Question 4

How often are codes updated?

Accepted Answer

CPT codes change every January 1st. ICD-10 codes update October 1st each year. This validator reflects the current year's codes. Make sure you're using the right year's codes for your billing date.

Question 5

What if a code seems right but the validator says it's wrong?

Accepted Answer

Double-check the spelling and format. CPT codes are exactly 5 digits. ICD-10 codes are 3-7 characters (e.g., A00.0). If formatting is correct, the code may be inactive or you may be using an outdated code list. Check official CMS sources.

Question 6

Do modifiers affect code validation?

Accepted Answer

Modifiers are separate from base codes. Enter the base CPT code first (without modifiers). Once valid, check if your modifier (-25, -50, -59, etc.) is appropriate. Some code+modifier combinations are not allowed.

Question 7

Can I validate bulk lists of codes?

Accepted Answer

Yes. Paste multiple CPT and ICD-10 codes separated by commas or new lines. For claim-style batch validation, you can upload a CSV.

Question 8

Is the validator approved for medical billing?

Accepted Answer

This tool is educational and advisory. Always verify codes against official sources (CMS, AMA, your payer) before billing. Consult your coding compliance officer for final validation.
