When billing E/M services on the CMS-1500 form or the 837P electronic claim, each CPT code must be associated with an identifier.

When billing Evaluation and Management (E/M) services on the CMS-1500 claim form or the 837P electronic claim, it is necessary to associate each Current Procedural Terminology (CPT) code with a unique identifier. This identifier is known as the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) diagnosis code.

Here are the logical steps for including E/M services on the CMS-1500 or 837P form:

1. Perform the E/M service for the patient according to the complexity and nature of the presenting problem, the time spent, and the level of decision-making required.

2. Select the appropriate E/M CPT code that best describes the service performed. The CPT codes for E/M services start with the numbers 99201 through 99499.

3. Determine the correct ICD-10-CM diagnosis code(s) that represents why the service was performed. Diagnoses codes must be to the highest level of specificity.

4. Enter the E/M CPT code on the CMS-1500 form in the section labeled "24D. Procedures, Services, or Supplies (CPT/HCPCS)" or the corresponding field on the 837P electronic claim.

5. Associate the diagnosis code(s) with the CPT code by entering the ICD-10-CM code in the section labeled "24E. Diagnosis Pointer" on the CMS-1500 form, or by linking the diagnosis code in the appropriate field on the electronic 837P claim. The "Diagnosis Pointer" refers to the lettered list item from box 21 on the CMS-1500, which contains the diagnosis codes you listed for the visit.

6. Ensure that all other required information, such as patient demographics, provider information, and date of service, is accurately filled in on the claim form.

7. Review all information for accuracy and completeness prior to submitting the claim to the insurance payer for reimbursement.
