Convert M25.839 to ICD-9-CM.
Lesion of ulnar nerve, right upper limb. G56.21 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM G56.21 became effective on October 1, 2019. This is the American ICD-10-CM version of G56.21 - other international versions of ICD-10 G56.21 may differ.

The most common surgical options to treat ulnar impaction syndrome (after physical therapy or other modalities have failed) include an ulnar shortening osteotomy (25390, Osteoplasty, radius or ulna; shortening) and hemiresection arthroplasty (25442, Arthroplasty with prosthetic replacement; distal ulna ).
The best choice is 718.83 (Unspecified derangement of joint; forearm) to represent instability. Ulnar impaction syndrome is also known as ulnar abutment syndrome, and can be a common complication after distal radial fracture.
What is Ulnar Impaction Syndrome? Ulnar impaction syndrome occurs when the ulna is relatively larger than it should be when compared to the radius. This forces the ulna to bear more of the weight and force to the wrist on that side of the arm.
2022 ICD-10-CM Diagnosis Code M24. 832: Other specific joint derangements of left wrist, not elsewhere classified.
Common symptoms are: pain, occasional edema, decreased wrist range of motion, decreased forearm rotation, and tenderness to palpation dorsally just distal to the ulnar head and just volar to the ulnar styloid process. The symptoms are commonly aggravated by forceful grip, forearm pronation, and ulnar deviation.
Ulnar impaction syndrome is a progressive degenerative condition, most commonly resulting from repetitive abutment of a lengthened ulna, with the TFCC, lunate, triquetrum, and lunotriquetral ligament.
The ulnar side of your wrist is the side of your “pinkie” finger (or small finger), and pain on this side can be very common.
Ulnar variance, also known as Hulten variance, refers to the difference in height between the joint surfaces of the distal radius and ulna.
Positive ulnar variance describes where the distal articular surface of the ulna is more than 2.5mm distal to the articular surface of the radius. It plays important role in wrist pathology such as ulnar impaction syndromes and thinning of the triangular fibrocartilage complex.
Negative ulnar variance is a condition in which the ulna is relatively shorter than the radius at the carpus. It was found in 21% of 203 normal wrists.
Studies suggest that between 3 and 9% of all sports injuries involve the wrist and/or hand. Andrew Hamilton looks at ulnar impaction, one of the more common injuries to affect this region, especially among older athletes.
Ulnar abutment syndrome can be treated by a variety of nonsurgical and surgical methods. These range from anti-inflammatory medications, immobilization, and corticosteroid injections to TFCC debridement, ulnar shortening osteotomies, and arthroscopic wafer procedures.
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.
Measured by drawing a transverse line at the level of the lunate fossa and a second transverse line at the level of the ulnar head, and determining the distance between the two lines. Positive ulnar variance increases with power grip and pronation. Consider pronated grip view. (Tomaino MM, J Hand Surg 2000;25Am:352). Normal = neutral (articular surface of distal ulna and radius equal). Postive (ulna longer) associated with ulnocarpal impaction, lunotriquetral ligament injurie and TFCC tears. Negative (ulna shorter) associated with carpal instability, Keinbock's disease.
Ulnolunate abutment is between the ulnar articular seat and the lunte. Ulnotriquetral abutment is between the ulnar styloid and the triquetrum. Ulnocarpal Impaction Syndrome Anatomy. Load bearing across the wrist: 82% radius, 18% ulna in neutral postion.
