Box 10d: Claim codes

By Dr. Daniel Turner, DC · Reviewed September 2, 2026

What goes in Box 10d of the CMS-1500?

A field for payer designated claim codes, most commonly condition codes the NUCC defines for specific situations. Most chiropractic claims leave it empty.

What does Box 10d mean for chiropractic billing?

The practical rule: empty unless a specific payer instruction says otherwise. Inventing content here does nothing useful and occasionally confuses adjudication.

How Cervica fills Box 10d

Cervica generates the CMS-1500 and its electronic 837P equivalent from the chart and the payer's own rules: identifiers from the verified insurance record, modifiers and codes per payer, and pre submission scrubbing that flags exactly the mistakes listed above before a claim leaves the building.
