Operation Definition
Measurement of motor, nerve, and related functions
Procedure Overview
This family covers formal testing of muscle strength, joint range of motion, reflexes, sensation, balance, and nerve conduction-related performance, typically performed by physical or occupational therapists. It is used after injuries such as fractures, joint replacements, spinal cord damage, or strokes, and in progressive conditions like multiple sclerosis or peripheral neuropathy, to determine exactly which physical capabilities have been affected.
The clinician puts the patient through structured movements and measurements - grip strength dynamometry, goniometry for joint angles, manual muscle testing, and balance or coordination scales - comparing results against expected function for the individual. Rather than a general observation of mobility, this produces objective, repeatable numbers that document severity and track change over time.
These results guide whether a rehabilitation program is warranted, what specific deficits to target, and how much progress has occurred at reassessment. Insurers often require this documented baseline before authorizing a course of therapy.
Anatomy & Axis Detail
Neurological System - Whole Body
Motor and/or nerve function assessment of the neurological system across the whole body is used when a patient's motor or sensory impairment cannot be attributed to a single region, such as after a diffuse neurological insult like severe traumatic brain injury, spinal cord injury with widespread effects, or a systemic neuromuscular disease affecting multiple limbs and the trunk simultaneously. Rather than isolating cervical, lumbar, or cranial territories, this evaluation surveys motor and nerve function comprehensively to build a full picture of the patient's overall functional status. This whole body framing is particularly relevant in early rehabilitation planning after catastrophic injury, where clinicians need a baseline across all major muscle groups and nerve distributions before designing a targeted therapy program.
Type Qualifier: Integumentary Integrity
Integumentary Integrity refers to an assessment of skin condition, including wounds, scarring, sensation, and tissue health, as it relates to a patient's rehabilitation status. It documents skin-related barriers to function or healing progress. This qualifier is distinct from Sensory Awareness/Processing/Integrity, which concerns neurological sensory perception broadly, not the physical condition of the skin itself.
Coding & Documentation
Coders select this family when the record documents a structured measurement of motor or nerve-related function - strength grades, range-of-motion degrees, or standardized balance scores - rather than a narrative impression like "patient appears weak." The qualifier must align with the specific tool or domain tested. A frequent mistake is defaulting to this code whenever a therapist "evaluates" a patient, without checking whether the note actually quantifies a measurable parameter as required by this root operation's definition. Another common error is failing to distinguish an initial evaluation from a progress reassessment, which can affect frequency and medical necessity review.
