What is the meaning of hypotonia?

Hypotonia may result from brain, spinal cord, nerve, or muscle damage and may be caused by numerous factors such as trauma, environment, genes, muscle, or central nervous system disorders. For example, hypotonia may be caused by brain damage because of lack of oxygen before birth, an infection, or issues with brain formation in the womb.

Some common causes of hypotonia can be a result of conditions such as:
  • Down syndrome
  • Muscular dystrophy
  • Cerebral palsy
  • Prader-Willi syndrome
  • Myotonic dystrophy
  • Marfan syndrome
  • Tay-Sachs disease



Those with hypotonia appear floppy, look like they have loose muscle tone, and have difficulty with coordination and movement.

Low muscle tone in children may mean more effort is required to move their muscles properly when engaging in activities. Depending on the severity of hypotonia, maintaining good posture may be difficult when sitting or standing. Also, children with low muscle tone have gross motor development delays. (e.g. rolling, sitting, walking).

It can also affect ADL skills and fine motor skills such as dressing, grooming, hygiene, manipulating articles of clothing, fasteners such as buttons, zippers, feeding, and eating, as well as writing and typing. Hypotonia can also affect one’s social participation, self-esteem, self-confidence, and ability to participate and perform well in school due to the limited ability to independently participate in group sports and school-related tasks.

What are the Hypotonia ICD 10 codes?

The International Classification of Diseases (ICD) aims to promote international comparability in the collection, processing, classification, and presentation of mortality statistics. The use of proper ICD-10 codes, such as Hypotonia ICD 10 codes can help improve the ability to understand risk and severity.

It’s important to incorporate proper Hypotonia ICD 10 codes to ensure reimbursement, medical necessity, and continued care. In occupational therapy practice, the ICD-10 is a billable/specific code used to indicate a diagnosis for reimbursement.

Utilizing ICD-10 codes that are client-specific is important as they improve the overall quality of care and management. It is also important to note that many therapists utilize related Hypotonia ICD 10 codes such as lack of coordination (R27.9), muscle weakness (M62.81), and/or codes of diagnoses such as Down syndrome, cerebral palsy, etc., as diagnosis codes along with hypotonia, if applicable to the client. Some of the different Hypotonia ICD 10 codes can be found in the chart below.

Assessment and evaluation of individuals with Hypotonia

Generally, when infants are born, physicians conduct routine checks of the newborn's muscle tone at 1 minute and 5 minutes after birth. Sometimes hypotonia develops later, but the condition is typically noticeable by 6 months.

If parents have any concerns, it should be mentioned to a child’s pediatrician so referrals for occupational therapy and/or physical therapy can be made. Occupational and physical therapists play a crucial role in the evaluation and assessment of those with hypotonia. The evaluation process begins with gaining a comprehensive understanding of a client's history, physical examination/observation, developmental history, skilled clinical observations, and standardized assessments.

Standardized assessments to evaluate hypotonia and assessments that evaluate gross motor skills, fine motor skills, and ADL skills that can indicate hypotonia based on assessment results can be found below:
  • Modified Ashworth Scale:
    • Ages: 6-12, 18-64
    • Scores range from 0-4, with 6 choices
    • 0 refers to no change in muscle tone with 4 referring to affected part, rigid in flexion/extension

Occupational therapy interventions for Hypotonia management

Occupational therapists play a foundational role in the intervention and management of hypotonia. Depending on the level of severity of hypotonia, infants with low muscle tone are provided with family-centered care via education regarding hypotonia and the environmental modifications necessary such as tummy time and proper positioning strategies during tummy time.

Intervention methods for children are generally focused on meeting milestones, improving gross motor skills, fine motor skills, and ADL skills through play-based and sensory-based activities such as obstacle courses, jungle gyms, scooter boards, and swings.

It is important to remember that each person with hypotonia presents differently and it is important to develop individualized treatment plans based on the assessment results. To address the underlying causes of hypotonia, occupational therapists may collaborate with nutritionists, doctors for medication management, and genetic counselors.

Assistive technology and assistive devices may also be a part of intervention methods. Occupational therapists will assess and evaluate the need for assistive devices and assistive technology to support function and participation. Based on assessment findings as well as considering age, environmental factors, and client preferences, occupational therapists will collaborate with the client and select and educate clients on appropriate assistive devices, such as such as adaptive seating, wheelchairs, braces, orthotics, splints, to meet the unique needs of the individual.



Addressing the psychosocial and emotional needs of families affected by hypotonia is a crucial aspect of treatment as well. Providing interventions for self-esteem, self-confidence, emotional regulation, environmental modifications, home exercise programming, support groups, community resources, counseling resources, emotional support, and developing collaborative goal setting and decision-making, are all important aspects of providing comprehensive, holistic, family-centered, and client-centered care.

It is crucial to foster a collaborative and multidisciplinary approach with a healthcare team as well as families as it ensures continuity of care, addresses the various needs of clients, and improves the quality of care, and overall client outcomes.

This allows for individualized treatment and interventions, improved treatment out-comes, as well as client outcomes, continuity of care, enhances the quality of life, and it overall contributes to a positive and meaningful impact in the lives of those impacted by hypotonia.

How EHR and practice management software can save you time with insurance billing for therapists

EHRs with integrated billing software and clearing houses, such as TheraPlatform, offer therapists significant advantages in creating an efficient insurance billing process. The key is minimizing the amount of time dedicated to developing, sending, and tracking medical claims through features such as automation and batching.

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.

  • 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 providers time when it comes to insurance billing for therapists.
