Weakness ICD-10 code

weakness icd-10 codes, icd-10 codes for weakness

Weakness ICD-10 codes are frequently used by physical therapists to designate weakness, or the state or condition of lacking strength – a common symptom of many medical conditions and impairments. Many times patients will seek out physical therapy to address the functional implications associated with weakness such as difficulty walking, inability to climb stairs, trouble completing work-related duties, inability to participate in sport, problems picking up and grasping items, etc. It is important to understand the cause of weakness in order to treat it effectively.

Some common causes of weakness are:
  • Muscular deconditioning and disuse atrophy after illness, injury or immobilization
  • Neuromuscular disease
  • Neurologic injury or illness
  • Medication or medical treatment side-effect
  • Metabolic disease or disorder

Because of its prevalence, you will likely encounter this condition frequently in your practice and understanding how to correctly utilize the Weakness ICD-10 codes is imperative for minimizing insurance claim denials. If you, like many therapists, have some experience searching for and selecting weakness ICD-10 codes but don’t have a good understanding of the who, what, when and why these codes are used, see the next section for an ICD-10 code primer. Following this introduction we will discuss the Weakness ICD-10 code in more detail.

An introduction to ICD-10 Codes

Who: All HIPAA-covered entities, including physical therapists, are required to submit ICD-10 codes if seeking reimbursement for services from an insurance company. 

What: The International Classification of Disease, 10th Revision (ICD-10) is a set of diagnosis, symptom, and procedure codes that physical therapists use daily in their practice. In 2015 physical therapists and all other HIPAA-covered healthcare providers transitioned from the ICD-9 to the current version, ICD-10. ICD-10 codes are alphanumeric codes. They begin with a letter and are always between three and seven characters with a decimal point placed after the third character. The more characters it has, the more specific it is.

Each code follows the following structure:
  • Characters 1-3 indicate the category of the diagnosis

  • Characters 4-6 indicate etiology, anatomic site, severity or other clinical detail

  • Character 7 is an extension value, for example:
    • A: Initial encounter (anything related to care of the initial injury)
    • D: Subsequent encounter (anything related to the phase of routine care of the injury while the patient recovers–this usually refers to rehabilitation)
    • S: Sequela (other conditions that may result from the presence of the primary condition)

Note, for fracture care, there are several more extensions (Example: P, G, K, which signify malunion, delayed healing, or nonunion for a subsequent encounter)

When: ICD-10 codes must be submitted with relevant documentation whenever reimbursement is sought for covered services either by the healthcare entity itself or by a patient.

Why: While it may seem like an extra step in an already detailed process of documentation and billing, ICD-10 codes are required for a specific reason. Not only do they identify a medical diagnosis, but perhaps more importantly, they help insurance companies understand why the care you are providing is medically necessary and therefore, reimbursable.



Weakness ICD-10 code: R53.1

When selecting Weakness ICD-10 codes, the code with the highest number of applicable characters should be chosen, at least on the first visit. In this case, R53.1 is the longest applicable code.

R53.1: Weakness

Is it billable?

Yes, code R53.1 can be utilized to indicate a diagnosis for billing/reimbursement purposes, however the more generic code R53 (malaise and fatigue) is considered too nonspecific to be used for billing/reimbursement purposes.

When should I use this code?

Weakness can be a symptom of many different conditions. This code is used to describe weakness limited mostly to one body area either unilaterally or bilaterally.

It can be used as a descriptor of the following according to ICD10 Data:
  • Arm weakness, both sides
  • Asthenia
  • Late effects of stroke, weakness of arms, legs
  • Leg weakness, both sides
  • Weakness as a late effect of stroke
  • Weakness as late effects of cerebrovascular accident
  • Weakness of bilateral hands
  • Weakness of bilateral legs
  • Weakness of both arms
  • Weakness of left arm
  • Weakness of left hand
  • Weakness of left leg
  • Weakness of right arm
  • Weakness of right hand
  • Weakness of right leg
  • Weakness, late effect of stroke

Additional Weakness ICD-10 code considerations

As you can see, while “weakness” is a billable Weakness ICD-10 code, there are several options for making this diagnosis more detailed. In addition to selecting the most accurate and detailed diagnosis code, here are several other coding strategies to take into consideration to help maximize reimbursement.

External cause codes (V00-Y99): specify an external cause resulting in the episode of weakness and may be used during the initial evaluation to increase specificity of the primary diagnosis:
  • Example 1: Hit by bike while crossing the street

V01: Pedestrian injured in collision with pedal cycle

  • Example 2: Experienced a workplace accident

W23: Caught, crushed, jammed or pinched in or between objects

Place of occurrence codes (Y92): place of occurrence codes may be used during the initial evaluation to increase specificity of the primary diagnosis:
  • Examples 1: Crossing residential street when hit by bicycle

Y92.414: Local residential or business street as the place of occurrence of the external cause

  • Example 2: Workplace accident on military base

Y92.13: Military base as the place of occurrence of the external cause
