# How Can I Resolve Medicare Claim Errors and Ensure Proper NPI Enrollment?

> Learn how to resolve Medicare claim errors and NPI enrollment issues

This article explains how to resolve Medicare claim errors and NPI enrollment issues for claims and ERA transactions.

## Overview

Medicare claim errors and enrollment issues can hinder the smooth processing of claims and remittances. This guide explains how to resolve common errors, including NPI-related eligibility issues.

## Workflow Instructions

### Resolving "Provider NPI Not Enrolled for Eligibility with Payer"

This error is typically triggered when the provider's NPI (National Provider Identifier) is not adequately enrolled or authorized for Medicare eligibility (HETS) transactions with the designated payer.

#### How to Resolve This Error

1. **Credential the NPI with Medicare** - Ensure that the provider's NPI is credentialed with Medicare and that they have an active PTAN (Provider Transaction Access Number).

2. **Complete HETS Attestation**:
   * Log in to your EDISS account
   * Navigate to the **Manage HETS Attestation** section and create a new attestation record
   * Enter Claim.MD's Unique ID: **UTUX**
   * Agree to the terms and submit the attestation

3. **Enroll NPI on a National Level** - Ensure you complete Medicare eligibility enrollment for only one state, as Medicare eligibility is processed nationally.
