ICD 10 Codes Physical Therapy 
Weakness ICD-10 code
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 R53.1 the Weakness ICD 10 code 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 R53.1 the Weakness ICD 10 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
When is an alternative Weakness ICD-10 code more appropriate?

Weakness ICD-10 code tips
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

Stay up to date: The Centers for Medicare and Medicaid Services publish an updated list of codes each year to go into effect October 1 and remain in effect until September 30 of the following year. Sites like ICD10 Data can also be helpful in identifying code changes once they update their list as announced on their homepage.

What are automation and batching?
- Automation refers to setting up software to perform tasks with limited human interaction.
- Batching or performing administrative tasks in blocks of time at once allows you to perform a task from a single entry point with less clicking.
Which billing and medical claim tasks can be automated and batched through billing software?
- Invoices: Create multiple invoices for multiple clients with a click or two of a button or set up auto-invoice creation, and the software will automatically create invoices for you at the preferred time. You can even have the system automatically send invoices to your clients.
- Credit card processing: Charge multiple clients with a click of a button or set up auto credit card billing, and the billing software will automatically charge the card (easier than swiping!)
- Email payment reminders: Never manually send another reminder email for payment again, or skip this altogether by enabling auto credit card charges.
- Automated claim creation and submission: Batch multiple claims with one button click or turn auto claim creation and submission on.
- Live claim validation: The system reviews each claim to catch any human errors before submission, saving you time and reducing rejected claims.
- Automated payment posting: Streamline posting procedures for paid medical claims with ERA. When insurance offers ERA, all their payments will post automatically on TheraPlatform's EHR.
- Tracking: Track payment and profits, including aging invoices, overdue invoices, transactions, billed services, service providers.
Utilizing billing software integrated with an EHR and practice management software can make storing and sharing billing and insurance easy and save physical therapy providers time when it comes to insurance billing for therapists.
