2022 ICD-10-CM Code S84
Injury of nerves at lower leg level
Code Classification
S84 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of injury of nerves at lower leg level. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
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
Specific Coding for Injury of nerves at lower leg level
Non-specific codes like S84 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for injury of nerves at lower leg level:
- NON-BILLABLE CODE - S84.0 for Injury of tibial nerve at lower leg level
- NON-BILLABLE CODE - S84.00 for Injury of tibial nerve at lower leg level, unspecified leg
- NON-BILLABLE CODE - S84.01 for Injury of tibial nerve at lower leg level, right leg
- NON-BILLABLE CODE - S84.02 for Injury of tibial nerve at lower leg level, left leg
- NON-BILLABLE CODE - S84.1 for Injury of peroneal nerve at lower leg level
- NON-BILLABLE CODE - S84.10 for Injury of peroneal nerve at lower leg level, unspecified leg
- NON-BILLABLE CODE - S84.11 for Injury of peroneal nerve at lower leg level, right leg
- NON-BILLABLE CODE - S84.12 for Injury of peroneal nerve at lower leg level, left leg
- NON-BILLABLE CODE - S84.2 for Injury of cutaneous sensory nerve at lower leg level
- NON-BILLABLE CODE - S84.20 for Injury of cutaneous sensory nerve at lower leg level, unspecified leg
- NON-BILLABLE CODE - S84.21 for Injury of cutaneous sensory nerve at lower leg level, right leg
- NON-BILLABLE CODE - S84.22 for Injury of cutaneous sensory nerve at lower leg level, left leg
- NON-BILLABLE CODE - S84.8 for Injury of other nerves at lower leg level
- NON-BILLABLE CODE - S84.80 for Injury of other nerves at lower leg level
- NON-BILLABLE CODE - S84.9 for Injury of unspecified nerve at lower leg level
- NON-BILLABLE CODE - S84.90 for Injury of unspecified nerve at lower leg level, unspecified leg
- NON-BILLABLE CODE - S84.91 for Injury of unspecified nerve at lower leg level, right leg
- NON-BILLABLE CODE - S84.92 for Injury of unspecified nerve at lower leg level, left leg
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code S84:
Code Also
Code AlsoA "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- any associated open wound S81
Type 2 Excludes
Type 2 ExcludesA type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- injury of nerves at ankle and foot level S94
7th Character Note
7th Character NoteCertain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category S84
7th Character
7th CharacterIndicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela
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.
