CMS-1500 Claim Form (02/12): Current Guidelines & How to Fill Out

The CMS-1500 (02/12) form stands as the current standard for professional paper claims in healthcare billing across the United States.

Approved by the OMB on June 10, 2013, and adopted by CMS, the 02/12 version replaced the older 08/05 form, becoming effective for claims received on and after April 1, 2014. Medicare began accepting this form on January 6, 2014, making it the exclusive accepted paper claim form by April 1, 2014.

Understanding Key Revisions in the CMS-1500 (02/12) Form

Item 17 Qualifiers: Identifying Provider Roles

One of the significant enhancements in the 02/12 form is the introduction of specific qualifiers for Item 17, which clarify the role of the provider. Accurate use of these qualifiers is crucial to prevent claims from being returned as unprocessable (RUC).

The qualifiers for identifying ordering, referring, or supervising roles are as follows:

• DN — Referring Provider: Used when a provider refers the patient to another provider for services.
• DK — Ordering Provider: Used when a provider orders services or tests for the patient.
• DQ — Supervising Provider: Used when a provider supervises services rendered by another healthcare professional (e.g., a physician supervising a physician assistant).

Providers must enter the appropriate qualifier to the left of the dotted vertical line in Item 17, followed by the provider’s NPI. Claims submitted with an NPI but without a valid qualifier will be rejected.

Item 21 & 24E: Current Diagnosis Reporting (ICD-10-CM Only)

The CMS-1500 (02/12) form significantly improved diagnosis reporting by utilizing letters (A-L) as diagnosis code pointers and expanding the capacity to 12 diagnosis codes per claim. It is critical to note that as of October 1, 2015, only ICD-10-CM codes are accepted for claims for all dates of service. Any mention of ICD-9-CM codes is now for historical context only.

Item 21: Diagnosis Codes

• Enter up to 12 ICD-10-CM diagnosis codes. Ensure the highest level of specificity is used for each code. These codes correspond to lines A-L, which are then referenced in Item 24E for each service line.
• Do not provide narrative descriptions in this field.
• Do not insert a period within the ICD-10-CM code.
• The ‘ICD Indicator’ must be entered as a single digit between the vertical, dotted lines. For all current claims, the indicator is:
• 0 — ICD-10-CM diagnosis
• The indicator ‘9 — ICD-9-CM diagnosis’ is no longer applicable for dates of service on or after October 1, 2015.

Item 24E: Diagnosis Pointers

• In Item 24E, you will reference the letter (A-L) from Item 21 that corresponds to the primary diagnosis for each service line. When completing this field, always use capital typeface. Pay special attention to clarity between letters like ‘I’ and ‘L’ to avoid errors.

Detailed CMS-1500 Field-by-Field Guide: Avoiding Common Errors

Beyond the major updates, several other items on the CMS-1500 (02/12) form require specific attention to ensure accurate claim submission. Here’s a CMS-1500 billing instructions 2024 overview for these fields:

Item 8: Patient Status

Form Version 02/12: This item should be left blank. No information is required here for current claims.

Item 9b: Other Insured’s Name

Form Version 02/12: This item should also be left blank. Information about other insureds is typically handled in electronic claim submissions or specific secondary claim forms.

Item 11b: Employer’s Name or Retirement Date

For Item 11b, enter the employer’s name if the insured is currently employed and coverage is through that employment. If the insured’s insurance status has changed, for example, due to retirement, enter the retirement date preceded by the word ‘RETIRED’. The date can be 6-digit (MMDDYY) or 8-digit (MMDDCCYY). This information should be provided to the right of the vertical dotted line. For example, ‘RETIRED 01012015’. This is crucial for verifying coordination of benefits.

Item 14: Date of Current Illness, Injury, or Pregnancy (LMP)

While the 02/12 form provides space for a qualifier in Item 14, Medicare does not utilize this information and a qualifier should not be entered. Simply provide the date (MMDDCCYY) if applicable, such as the date of the last menstrual period (LMP) for pregnancy-related services or the onset date of an illness/injury.

What’s Important for CMS-1500 in 2024? Staying Compliant

Even though the CMS-1500 (02/12) form has been standard for years, staying current with CMS-1500 billing instructions 2024 requires attention to ongoing compliance requirements and best practices. While the form itself hasn’t seen recent structural changes, interpretation and specific payer requirements can evolve.

• Strict ICD-10-CM Adherence: Ensure all diagnosis coding is compliant with the latest ICD-10-CM updates. Annual updates to the ICD-10-CM code set are crucial.
• Payer-Specific Requirements: Always check individual payer guidelines as some commercial payers may have unique requirements for specific fields or attachments, even when using the standard CMS-1500 form.
• Electronic vs. Paper Claims: While this post focuses on paper claims, remember that electronic claims (837P) are often preferred and can lead to faster processing. Understand when paper claims are appropriate or required.
• Proper Use of NPI: Your National Provider Identifier (NPI) must be correctly entered in all relevant fields (e.g., Items 17b, 24J, 33a).
