2022 ICD-10-CM Code S84.20XA
Injury of cutaneous sensory nerve at lower leg level, unspecified leg, initial encounter
Code Classification
S84.20XA is a billable diagnosis code used to specify a medical diagnosis of injury of cutaneous sensory nerve at lower leg level, unspecified leg, initial encounter. The code S84.20XA is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code S84.20XA might also be used to specify conditions or terms like closed injury cutaneous sensory nerve of leg, injury of cutaneous sensory nerve at lower leg level, injury of cutaneous sensory nerve of lower limb, injury of cutaneous sensory nerve of lower limb, injury of cutaneous sensory nerve of lower limb , injury of nerve at lower leg level, etc.
S84.20XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like injury of cutaneous sensory nerve at lower leg level unspecified leg. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.
Unspecified diagnosis codes like S84.20XA are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Coding Guidelines
The appropriate 7th character is to be added to each code from block Injury of nerves at lower leg level (S84). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Closed injury cutaneous sensory nerve of leg
- Injury of cutaneous sensory nerve at lower leg level
- Injury of cutaneous sensory nerve of lower limb
- Injury of cutaneous sensory nerve of lower limb
- Injury of cutaneous sensory nerve of lower limb
- Injury of nerve at lower leg level
- Open injury cutaneous sensory nerve of lower limb
Convert S84.20XA to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code S84.20XA its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Leg Injuries and Disorders
Your legs are made up of bones, blood vessels, muscles, and other connective tissue. They are important for motion and standing. Playing sports, running, falling, or having an accident can damage your legs. Common leg injuries include sprains and strains, joint dislocations, and fractures (broken bones).
These injuries can affect the entire leg, or just the foot, ankle, knee, or hip. Certain diseases also lead to leg problems. For example, knee osteoarthritis, common in older people, can cause pain and limited motion. Problems in your veins in your legs can lead to varicose veins or deep vein thrombosis.

Peripheral Nerve Disorders
Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.
There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.
Symptoms often start gradually, and then get worse. They include
- Numbness
- Pain
- Burning or tingling
- Muscle weakness
- Sensitivity to touch
Treatment aims to treat any underlying problem, reduce pain and control symptoms.
