When Does CPT Code 97110 Need a Modifier?
Navigate CPT 97110 medical coding. Understand precisely when and why modifiers are crucial for accurate therapeutic exercise claim submission.
Medical coding uses Current Procedural Terminology (CPT) codes to standardize reporting healthcare services. Modifiers are two-character additions to CPT codes that supply extra information about a service without altering its fundamental definition. This article clarifies when CPT code 97110, which describes therapeutic exercises, requires a modifier for accurate billing and claim processing.
CPT Code 97110: Definition and Application
CPT code 97110 is defined as “Therapeutic procedure, one or more areas, each 15 minutes; therapeutic exercises to develop strength and endurance, range of motion and flexibility.” This code encompasses activities aimed at restoring or improving a patient’s physical capabilities, such as range of motion, resistance, and aerobic exercises.
This code is commonly used in physical therapy, occupational therapy, and chiropractic practices. It is a time-based code, with billing determined by the duration of direct, one-on-one patient contact. Most payers, including Medicare, follow an “8-minute rule,” requiring at least 8 minutes of service within a 15-minute increment to bill for one unit of 97110.
The Purpose of Modifiers in Medical Coding
CPT modifiers provide additional information about a service without changing its core definition. These two-digit codes are appended to CPT codes to communicate specific circumstances to payers. Modifiers clarify situations such as when a service was performed by multiple providers, when multiple services were performed during the same encounter, or when a procedure was bilateral.
The use of modifiers helps ensure accurate reimbursement and prevent claim denials. They provide necessary detail to explain variations in how a service was performed, which is essential for proper claim processing. Correct modifier application helps healthcare providers receive appropriate compensation and maintain compliance with payer guidelines.
Scenarios Requiring a Modifier with 97110
CPT code 97110 often requires a modifier to accurately convey the specific circumstances of the therapeutic exercise to the payer. One common scenario is when 97110 is performed alongside another distinct service on the same day by the same provider. A modifier indicates these are separate and not bundled services, preventing potential denials.
Another situation requiring a modifier arises when therapeutic exercises are performed on separate anatomical sites during the same session. Different body parts warrant a modifier to distinguish the services. When different healthcare professionals, such as a physical therapist and an occupational therapist, provide services to the same patient on the same day, modifiers identify the discipline.
Bilateral procedures, where exercises are performed on both sides of the body, also necessitate a modifier to indicate the dual application of the service.
Specific Modifiers for CPT Code 97110
Several specific modifiers are commonly used with CPT code 97110 to provide billing information. Modifier 59, “Distinct Procedural Service,” is appended when 97110 is performed with another distinct service on the same day. This modifier signals the therapeutic exercise was independent and should be separately reimbursed, preventing inappropriate bundling. More specific “X” modifiers (XE, XS, XP, XU) should be used in place of modifier 59 when applicable, offering greater specificity regarding the reason for the distinct service, such as a separate encounter (XE) or separate structure (XS).
Therapy-specific modifiers are also essential for CPT 97110. The GP modifier indicates services delivered under an outpatient physical therapy plan of care. The GO modifier is used for services under an outpatient occupational therapy plan of care, and GN for speech-language pathology. These modifiers identify the therapy discipline providing the service, which is often required by payers.
Modifier 25, “Significant, Separately Identifiable Evaluation and Management Service,” is used if an evaluation and management (E/M) service is provided on the same day as 97110 and is distinct from the therapeutic exercises. This modifier communicates the E/M service was significant and separately billable, not merely part of the therapeutic procedure. Modifier 50, “Bilateral Procedure,” is applied when therapeutic exercises are performed on corresponding bilateral body parts during the same session.
