Muscle Atrophy VA Rating Explained

VA disability ratings for muscle atrophy range from 10% to 80% and are based on the severity of symptoms and its negative affect on a veteran’s work, life, and social functioning to include any functional impairment or loss.

The VA uses several diagnostic codes under 38 CFR § 4.124a to evaluate muscle atrophy, ranging from mild to severe cases.

For example, progressive muscular atrophy is rated under Diagnostic Code 8023 with a minimum VA rating of 30% while mild to severe muscle atrophy is rated under Diagnostic Code 8520 from 10% to 80% with breaks at 20%, 40%, and 60%.

Alright, let’s explore muscle atrophy, causes, symptoms, and risk factors in military veterans, how it’s rated by the VA, how to prove service connection, and some pro tips and strategies to maximize your VA disability.

Summary of Key Points

• VA Disability Ratings for Muscle Atrophy: Ratings range from 10% to 80%, based on the severity of symptoms and their impact on a veteran’s daily life, work, and social functioning. Functional impairment or loss is also considered in determining your final VA rating.

• Multiple Diagnostic Codes for Muscle Atrophy: The VA evaluates muscle atrophy under various diagnostic codes, including Diagnostic Code 8023 (Progressive Muscular Atrophy) with a minimum rating of 30%, and Diagnostic Code 8520 for sciatic nerve-related muscle atrophy, ranging from 10% to 80%.

• Causes and Symptoms: Muscle atrophy can result from prolonged inactivity, nerve damage, chronic illnesses, or nutritional deficiencies, leading to visible muscle loss, weakness, and impaired mobility.

• Service Connection and Maximizing Your VA Benefits: Veterans must establish a direct, secondary, or aggravated service connection for muscle atrophy. Proper documentation, medical evidence, and filing for secondary conditions can help maximize VA ratings.

What is Muscle Atrophy?

Muscle atrophy refers to the wasting or loss of muscle tissue, often resulting from prolonged inactivity, neurological conditions, or injury.

There’s three types of muscle atrophy: physiologic, pathologic, and neurogenic.

Muscle atrophy can affect all areas of the body, including but not limited to, muscles in the arms, legs, back, abdomen, and even facial muscles, depending on the underlying cause.

It can lead to significant weakness and loss of mobility, affecting a veteran’s ability to perform daily activities, maintain employment, and engage in social and recreational activities.

Causes of Muscle Atrophy

The primary causes of muscle atrophy include:

• Prolonged Inactivity: Extended periods of immobility, such as bed rest or recovery from surgery, can lead to muscle wasting.

• Nerve Damage: Neurological conditions, such as peripheral neuropathy or spinal cord injuries, can cause nerve damage that leads to muscle atrophy.

• Chronic Illnesses: Conditions like ALS (Amyotrophic Lateral Sclerosis), muscular dystrophy, and other degenerative diseases can cause muscle wasting over time.

• Nutritional Deficiencies: Inadequate protein and calorie intake can also contribute to muscle atrophy.

Symptoms of Muscle Atrophy in Veterans

Veterans experiencing muscle atrophy might notice the following symptoms:

• Visible Decrease in Muscle Mass: Muscles appear smaller or “sunken in” compared to their normal state.

• Weakness and Fatigue: Difficulty lifting objects, climbing stairs, or performing tasks that require strength and endurance.

• Loss of Coordination: Impaired motor function, affecting balance and dexterity.

• Pain or Discomfort: Soreness in the affected muscles, particularly after periods of activity or exertion.

• Difficulty with Everyday Movements: Challenges with tasks like sitting up, standing, or walking.

• Muscle Twitching or Spasms: Involuntary contractions that can be painful or uncomfortable.

• Impaired Reflexes: Slower or reduced reflexive responses in the affected areas.

• Limited Range of Motion: Stiffness or reduced flexibility in joints and muscles.

• Postural Changes: Slumping or altered body alignment due to weakened muscles.

Risk Factors for Muscle Atrophy in Military Veterans

Several factors can increase the risk of muscle atrophy among veterans, including:

• Injuries Sustained During Service: Combat injuries, traumatic brain injuries (TBI), and spinal cord injuries can lead to nerve damage and muscle atrophy.

• Prolonged Immobility: Extended inactivity due to hospitalization or recovery can cause muscle wasting.

• Chronic Pain and Limited Mobility: Conditions that limit movement increase the risk of muscle atrophy.

• Exposure to Environmental Toxins: Contact with hazardous substances during deployment may lead to muscle loss.

• Chronic Illness: Diseases like diabetes, COPD, or heart disease can contribute to muscle atrophy.

• Nutritional Deficiencies: Lack of adequate protein or nutrients can accelerate muscle loss.

• Mental Health Conditions: Depression or PTSD can reduce physical activity, leading to muscle atrophy.

• Medications: Long-term use of certain medications, such as corticosteroids, can weaken muscles.

What is the VA Disability Rating for Muscle Atrophy?

The VA mainly uses 38 CFR § 4.124a, schedule of ratings for neurological conditions and convulsive disorders to determine VA ratings for muscle atrophy.

Here’s a breakdown of the relevant diagnostic codes and rating criteria:

VA Rating for Progressive Muscular Atrophy (Diagnostic Code 8023)

The VA assigns a minimum disability rating of 30% for progressive muscular atrophy under Diagnostic Code 8023.

This rating is given when there are confirmed residuals of the condition that are observable and measurable.

Here’s a detailed breakdown:

• Minimum VA Rating: The 30% rating is the baseline for progressive muscular atrophy, acknowledging the presence of the condition and its impact on the veteran’s health. This rating is assigned when there are ascertainable residuals, meaning that the effects of the condition are evident and can be objectively verified.

• Ascertainable Residuals Requirement: The VA requires ascertainable residuals to get a rating under diagnostic code 8023. This means that symptoms must be observable and measurable, such as muscle wasting, loss of strength, or functional impairment directly related to muscular atrophy.

• Handling Subjective Residuals: If residuals are subjective (like headaches, dizziness, or fatigue) and cannot be objectively measured, the VA will rely on the recorded diagnosis and consistency of symptoms with the disease. These subjective symptoms will be accepted if they are consistent with the known progression of the disease and are not more likely attributed to another condition.

• VA Ratings Above 30%: Higher ratings can be assigned if the severity of the condition and its residuals significantly impact the veteran’s life. When higher ratings are justified, the VA will use additional diagnostic codes to specify the basis for these evaluations. For example, if the condition leads to severe loss of motor function or affects multiple body systems, the veteran could receive a higher rating under different codes that more accurately reflect the level of impairment.

• Documentation and Evidence: Veterans seeking a rating above the minimum 30% must provide comprehensive medical documentation that demonstrates the extent and severity of the residuals. This could include medical tests, clinical notes, and evidence of how the condition affects daily functioning.

VA Rating for Muscle Atrophy (Diagnostic Code 8520)

Mild to severe muscle atrophy related to the sciatic nerve is rated under Diagnostic Code 8520 from 10% to 80% with breaks at 20%, 40%, and 60%, depending on the severity of nerve paralysis and its impact on muscle function below the knee.

Here’s a detailed breakdown of the VA rating criteria:

• 80% VA Rating – Complete Paralysis: This rating is assigned when there is complete paralysis of the sciatic nerve. In this condition, the foot dangles and drops, and there is no active movement possible of muscles below the knee. Additionally, flexion of the knee is significantly weakened or, in rare cases, completely lost. This rating reflects severe disability and loss of function due to nerve damage.

• 60% VA Rating – Severe Incomplete Paralysis: This rating is given for severe, but not complete, paralysis. There is marked muscular atrophy, which indicates significant loss of muscle mass and strength due to nerve dysfunction. Veterans may still have some degree of movement, but it is severely limited, and there may be noticeable wasting of the muscles below the knee.

• 40% VA Rating – Moderately Severe Incomplete Paralysis: This rating level is assigned when there is moderately severe impairment. There is notable muscle atrophy and functional limitation, but not to the extent that qualifies as severe. The veteran may have difficulty performing movements with the lower leg, but some function remains.

• 20% VA Rating – Moderate Incomplete Paralysis: Moderate incomplete paralysis is characterized by a significant reduction in muscle strength and function but with less severe symptoms compared to the higher ratings. There may be some atrophy, but it is not as pronounced, and the veteran can still perform some movements with moderate difficulty.

• 10% VA Rating – Mild Incomplete Paralysis: This is the lowest compensable rating for sciatic nerve involvement. It indicates a mild reduction in muscle strength and function with little to no noticeable atrophy. Symptoms may include mild weakness, numbness, or tingling, but the overall impact on daily functioning is minimal.

Important Considerations:

• Muscle Atrophy and Functional Impairment: The degree of muscle atrophy and functional impairment plays a crucial role in determining the appropriate rating. The VA will evaluate how much the muscle has wasted, the impact on strength and mobility, and how these factors affect the veteran’s ability to perform everyday activities.

• Documentation and Medical Evidence: To receive these ratings, veterans must provide medical evidence, such as a nerve conduction study or electromyography (EMG), that confirms the level of sciatic nerve involvement and its impact on muscle function.

Other Potential Diagnostic Codes for Muscle Atrophy

The VA might use other diagnostic codes to rate muscle atrophy based on the severity and location of the atrophy as well as the underlying conditions causing it.

Here are some other relevant diagnostic codes:

• Diagnostic Code 5021 (Myositis): This code is used when muscle inflammation leads to atrophy. The VA rates it according to the limitation of motion affected by the condition.

• Diagnostic Code 5301-5329 (Muscle Injuries): These codes cover specific injuries or conditions related to different muscle groups, and muscle atrophy can be rated if it significantly impacts muscle function.

How to Establish Service Connection for Muscle Atrophy

To receive a VA disability rating for muscle atrophy, a veteran must establish a service connection through one of the following avenues:

• Direct Service Connection: The veteran must show that their muscle atrophy began during or was directly related to their military service. This often involves providing service treatment records, medical evidence of injury, or illness during service that led to muscle loss.

• Secondary Service Connection: Muscle atrophy can be secondary to other service-connected conditions, such as nerve injuries or chronic pain. A detailed nexus letter from a medical professional is necessary to establish how the primary condition has led to muscle atrophy.

• Service Connection via Aggravation: If a pre-existing condition of muscle atrophy worsens due to service-related activities or injuries, the veteran may qualify for an increased rating based on the aggravation of the condition.

List of VA Secondary Conditions to Muscle Atrophy

Veterans suffering from muscle atrophy may experience a range of associated conditions that can be considered for VA disability compensation if linked as secondary conditions.

These include:

• Chronic Pain: Conditions like fibromyalgia or complex regional pain syndrome can result from or worsen due to muscle atrophy.

• Anxiety and Depression: The psychological impact of living with muscle atrophy can lead to mental health conditions such as anxiety and depression.

• Joint Pain and Arthritis: Muscle atrophy can lead to joint instability and increased stress on joints, causing pain and arthritis.

• Sciatica and Nerve Pain: Atrophy in the lower limbs can lead to nerve pain, including sciatica, due to reduced muscle support around nerve pathways.

• Peripheral Neuropathy: Loss of muscle mass can exacerbate nerve damage, contributing to conditions like peripheral neuropathy.

Muscle Atrophy VA Claim Tips: How to Maximize Your VA Rating for Muscle Atrophy

Here are some pro tips and strategies to maximize your VA rating for muscle atrophy:

• Document Symptoms Thoroughly: Keep detailed records of all symptoms, treatments, and their impact on your daily life. Ensure your symptoms are documented in your medical records.

• Seek Medical Treatment: Regularly visit your healthcare provider to document the persistence and severity of symptoms. Continuity of care is important.

• Get a Nexus Letter: If you’ve been out of the military for more than 12-months (and aren’t already service connected) or if your endometriosis is a secondary condition, a nexus letter from a qualified healthcare provider can establish the connection to your primary service-connected disability.

• File for Secondary Conditions: If you have related conditions such as chronic pain, depression, or other health issues that have developed due to muscle atrophy, it’s important to file for these secondary conditions. Make sure you get a nexus letter for a secondary condition.

• Appeal if Necessary: If your initial rating is lower than expected, consider filing an appeal with additional evidence to support your claim.
