# 12 Diagnosis Code Support
> Learn about 12 diagnosis code support per claim in Elation Billing
This article provides an overview of the 12 diagnosis code support feature in Elation Billing.
## Overview
### What is 12 Diagnosis Code Support?
Elation Billing now supports up to 12 Diagnosis Codes per claim, even with only one charge line. This feature aligns with CMS-1500 form requirements and supports value-based and quality programs that require more reporting on patient conditions.
### Why is 12 Diagnosis Code Support important?
More value-based and quality programs require comprehensive reporting on patient conditions. Having support for 12 diagnosis codes ensures you can capture all relevant diagnoses for accurate claims and program compliance.
## How it works
Elation Billing automatically selects a maximum of 12 diagnosis codes when submitting a claim. You do not need to manually remove diagnosis codes from the superbill before submission — the system handles this for you based on the CMS-1500 form limit.
### What you need to know
* You can enter more than 12 diagnosis codes on a bill in the EHR.
* When the claim is submitted, Elation Billing automatically selects up to 12 diagnosis codes for transmission.
* Manual trimming of diagnosis codes is **not** required as part of your standard workflow.
Changes made to the superbill for billing purposes do **not** affect the patient's medical record in the EHR system. Comprehensive patient diagnosis history remains intact in the EHR.
### Troubleshooting
If you receive a claim rejection related to an invalid diagnosis pointer or more than 12 diagnosis codes being transmitted, reach out to Elation Support using **Help** → **Contact Elation Support**.
