ICD 10 code for deconditioning

An ICD-10 code for deconditioning is used to describe a loss of physical and physiological function due to inactivity. The impact of deconditioning on a person's functional capacity depends on two main factors: the duration of inactivity and the individual's baseline health and function before deconditioning. 

Summary

• Prolonged inactivity can impact the cardiovascular, pulmonary, musculoskeletal, digestive, circulatory, and psychological systems. Physical therapy plays a key role in reversing these effects through personalized treatment plans.
• Using an ICD code for deconditioning like R53.81 (deconditioning), R54 (chronic debility), and M62.81 (muscle weakness) helps justify treatment and minimize insurance claim denials. Documenting prior and current function levels supports medical necessity. Enrolling in an insurance billing course for therapists can help providers enhance their knowledge.
• Therapists should assess the full spectrum of a patient’s medical history and consider referrals to other specialists as needed (e.g., cardiology, occupational therapy, speech therapy) for comprehensive treatment.
• Leveraging an EHR like TheraPlatform for efficient documentation and claim submission can help therapists tackle billing with ease.

In either case, physical therapists often help patients recover from deconditioning through an individualized exercise program. This post will outline the effects of deconditioning, how to select the appropriate ICD-10 code for deconditioning, and considerations for physical therapists treating patients with this condition.

The deconditioning spectrum

The effects of deconditioning lie on a spectrum. Healthy adults who exercise regularly, for example, may notice a decline in exercise capacity after a week recovering from the flu, but should return to daily activities fairly easily. 

Someone who lives a sedentary lifestyle and deals with health conditions that impact their function at baseline may find themselves struggling to complete daily activities after a weeklong illness. 

In contrast to the effects of a brief illness or period of inactivity, prolonged inactivity or bed rest due to a serious illness, injury, or surgery will eventually affect everyone's physiological capacity and can lead to substantial reductions in function.

The "use it or lose it" concept helps explain the widespread impact of deconditioning on all body systems. All physiological systems adapt to the low demand associated with inactivity through atrophy and downregulation. 

As a person begins to recover or increase their activity level, it takes time for the body to adapt to the increased demands. This discrepancy in supply and demand reflects the impact of deconditioning. 

Let's take a look at how deconditioning can impact different body systems:

• Cardiovascular system: Diminished cardiac output and blood pressure in upright positions (orthostatic hypotension) can result in decreased activity tolerance, reduced blood pressure control, and elevated heart rate
• Pulmonary system: Decreased respiratory and ventilatory functions can increase the risk of pulmonary illnesses like pneumonia and impair respiratory support during activity
• Digestive system: Changes in appetite and reduced digestive function can lead to weight loss or weight gain, and problems like constipation
• Musculoskeletal system: Muscle atrophy and weakness, osteoporosis, loss of flexibility, and pain often develop and impact overall function.
• Circulatory system: Increased blood viscosity, blood stasis, and reductions in overall circulation can result in blood clots and swelling.
• Psychological: Confusion, disorientation, anxiety, depression, reduced self-efficacy, and motivation can all be affected by inactivity.

As you can see, physical therapists combating deconditioning positively affect multiple physiological systems, improving overall health and function.

How to use an ICD 10 code for deconditioning

While many adults can manage the effects of mild deconditioning independently, physical therapy plays an essential role in preventing and managing moderate-to-severe deconditioning. 

Minimizing claim and authorization denials begins with thorough documentation and appropriate coding practices when using ICD-10 codes for deconditioning.

Your subjective interview can glean important information that will help you document why skilled physical therapy is needed to treat a patient's deconditioning.

Here are a few things you should consider adding to your initial evaluation:

• Ask about prior levels of function–the actual functional impact of deconditioning can only be understood relative to a person's previous level of function.
• Ask about the current level of function–inquire about their difficulties in daily activities, including activities where they need more assistance, have reduced the volume/intensity, or have stopped altogether.
• Administer activity and participation-level outcome measures like the Lower Extremity Functional Scale to quantify their level of impairment, provide a target to set functional goals, and track over time to assess progress.

Selecting the appropriate ICD-10 code for deconditioning helps minimize claim denials and increases the likelihood that treatment authorization requests will be approved. You have some options when choosing an ICD 10 code for deconditioning. 

ICD 10 code for deconditioning options

If other impairments, such as contractures, imbalance, or pain, are present as a result of deconditioning, ICD-10 codes for these conditions may be appropriate.

Deconditioning treatment tips

Deconditioned patients can present as a simple case of strengthening or a medically complex, multidisciplinary case. It's easy to approach deconditioning as a simple muscle weakness and cardiac deconditioning case. However, considering all physiologic and psychologic systems leads to a safer and more well-rounded approach to care.

Below are some tips to help you improve the management of patients with deconditioning:

• To obtain a complete picture of the patient's medical status, perform a thorough chart review, including medical history and medication list.
• Screen the patient for symptoms or impairments that indicate a need for a multidisciplinary approach or referral to an outside provider. Examples may be referring to a cardiologist to evaluate cardiac symptoms, a pelvic floor therapist to evaluate bowel and bladder symptoms, an occupational therapist to address ADL impairments, or speech therapy to address cognitive complaints.
• Take time to get a complete picture of the patient's prior and current level of function, and ask them to prioritize their functional goals to help guide your treatment plan.
• Create functional goals that focus on improving their overall level of function.
• Individualize a progressive treatment plan to address symptoms like muscle performance impairments, cardiorespiratory deconditioning, balance problems, walking endurance limitations, and more.

Strength training, stretching, aerobic conditioning, balance training, manual therapy, and more can all be useful when treating a patient with deconditioning. Get creative and focus on the most important activities for your patient.

Treating individuals with deconditioning can be very rewarding. You have a chance to improve their quality of life and independence and empower them to get back to the life they love, all by using the skills you practice daily. And by using the proper ICD 10 code for deconditioning, you can avert administrative headaches that prevent reimbursement, which is good news for you and your practice.

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