Idiopathic progressive neuropathy
Ulnar neuropathy occurs when there is damage to the ulnar nerve. This nerve travels down the arm to the wrist, hand, and ring and little fingers. It passes near the surface of the elbow. So, bumping the nerve there causes the pain and tingling of "hitting the funny bone."
ICD-10 Code for Lesion of ulnar nerve, left upper limb- G56. 22- Codify by AAPC.
The ulnar nerve runs behind the medial epicondyle on the inside of the elbow. Beyond the elbow, the ulnar nerve travels under muscles on the inside of your forearm and into your hand on the side of the palm with the little finger.
Lesion of ulnar nerve, unspecified upper limb The 2022 edition of ICD-10-CM G56. 20 became effective on October 1, 2021.
Peripheral Nerve Injury of the Upper Extremity The ulnar nerve originates from the medial cord of the brachial plexus and travels down the anterior arm, positioned either medial or posterior to the brachial artery.
The ulnar nerve is one of five nerve branches of the brachial plexus. This nerve bundle sends sensory information and helps you move your shoulders, arms and hands. The brachial plexus starts as nerve roots in the cervical spine in the neck.
The upper arm is served by several major nerves, including the axillary, radial, and musculocutaneous nerves. Running through the superior and posterior portions of the shoulder, the axillary nerve stimulates the deltoid muscle and receives information from sensory receptors in this region.
pinky sideThe forearm consists of two bones, the radius and the ulna, with the ulna is located on the pinky side and the radius on your thumb side.
The ulnar nerve innervates the flexor muscles of the forearm including the flexor carpi ulnaris and flexor digitorum profundus. It also innervates the intrinsic muscles of the hand including the palmaris brevis, lumbricals, hypothenar and interossei muscles.
Cubital tunnel syndrome happens when the ulnar nerve, which passes through the cubital tunnel (a tunnel of muscle, ligament, and bone) on the inside of the elbow, is injured and becomes inflamed, swollen, and irritated.
CPT code 64718 is used to describe Transposition and/or neuroplasty of the ulnar nerve at the elbow. This code is used commonly to report simple decompression of the ulnar nerve, such as anterior transposition or subcutaneous transposition.

Ulnar nerve entrapment is a condition where the ulnar nerve becomes trapped or pinched due to some physiological abnormalities.
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code G56.22 and a single ICD9 code, 354.2 is an approximate match for comparison and conversion purposes.
Finally, and perhaps most important, the ulnar nerve can become entrapped at the arcade of Struthers, in the cubital tunnel (ulnar collateral ligament and aponeurosis between the two heads of the flexor carpi ulnaris; Fig. 27.1 ), or within the flexor carpi ulnaris muscle. The nerve lengthens and becomes taut with elbow flexion.
Repetitive or incorrect throwing can lead to damage of the ulnar nerve at the elbow. Biomechanical risk factors (repetitive holding of a tool in one position), obesity, and other associated upper extremity work-related musculoskeletal disorders (especially medial epicondylitis and other nerve entrapment disorders) have also been associated with ...
The ulnar nerve may be felt subluxing with flexion and extension of the elbow. Sensory deficits may be noted in the fifth and ulnar half of the fourth digits. Atrophy of the intrinsic hand muscles and hand weakness may be noted as well (although this is generally seen in more advanced cases).
If the ulnar nerve is entrapped at the elbow, both the dorsal ulnar cutaneous nerve (which arises just proximal to the wrist) and the palmar cutaneous branch of the ulnar nerve will be affected. Patients will therefore complain of numbness or paresthesias in the dorsal and volar aspects of the fifth and ulnar side of the fourth digits. Hand intrinsic muscle weakness may be apparent. In cases of severe ulnar neuropathy, clawing of the fourth and fifth digits (with attempted hand opening) and atrophy of the intrinsic muscles may be noted by the patient ( Fig. 27.2 ). Symptoms may be exacerbated by elbow flexion. Pain may be noted and may radiate proximally or distally.
First, the nerve has a superficial anatomic location at the elbow. Hitting the “funny bone” (ulnar nerve at the elbow) creates an unpleasant sensation that most people have experienced. If the ulnar nerve is susceptible to subluxation, further injury may result.
The ulnar nerve is the continuation of the medial cord of the brachial plexus at the level of the axilla. Ulnar neuropathy at the elbow is the second most common entrapment neuropathy. Only carpal tunnel syndrome (median neuropathy at the wrist) is more frequent.
Abstract. Ulnar nerve entrapment at the elbow is a common source of entrapment neuropathy. It is the most common area of entrapment for the ulnar nerve, and the second most common of all entrapment neuropathy (after carpal tunnel syndrome). Symptoms may include numbness in the fifth digit and the ulnar aspect of the fourth digit.
