What Is an LL Modifier?

An LL modifier code is entered on medical paperwork when rental fees are applied to the overall purchase price for equipment used by patients. The code is a designation that works in accordance with the health insurance portability and accountability act -- HIPAA -- guidelines. HIPAA was created in 1996 to secure patient information within the healthcare industry.

Modifiers

• An LL modifier is used to signify changes in billing without altering the original code definition. LL coding indicates equipment has been leased or purchased. The additional LL modifier shows the equipment is still being purchased, but conditions have changed slightly. The item will be on a rent-to-own basis, with lease payments being applied to the total cost, giving the patient ownership after a pre-determined period of time.

Healthcare Coding System

• LL modifiers are part of a larger system known as the healthcare common procedure coding system -- HCPCS. Under HIPAA, all medical procedures must be documented using two-digit alpha or numeric HCPCS codes on claims and billing forms. Medical personnel including providers, pharmacists, billing and coding staff must be familiar with the system to avoid costly errors. According to the HCPCS code online book, there are thousands of codes that can be used on a daily basis.

DME Equipment

• The International Organization for Standardization indicates that LL coding is used for equipment with a DME designation. The definition for durable medical equipment -- DME -- differs by state, but every location requires that pieces are able to be used repeatedly. In some states, the equipment must be capable of functioning outside of a medical facility.

History

• HIPAA went into effect in 1996, but HCPCS has existed since 1978 to standardize identification of medical services. Level 1 coding is referred to as the Current Procedural Terminology. Level 2 coding, where LL modifiers are commonly seen, deal with medical services omitted from level 1. Medical equipment and supplies receive level 2 coding. The Centers For Medicare and Medicaid Services have the power to create and adjust coding as needed.
