M18.12 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M18.12 became effective on October 1, 2021. This is the American ICD-10-CM version of M18.12 - other international versions of ICD-10 M18.12 may differ. osteoarthritis of spine ( M47.-)
The first CMC joint (known as the thumb's saddle joint) is the most mobile, especially during the movement of opposition. (The CMC joint of the thumb is extremely important and is described separately in a subsequent section.)
The thumb carpometacarpal (CMC) joint, a biconcave-convex saddle joint, consists of the articulation between the first metacarpal of the thumb and the trapezium carpal bone. Other significant articulations of the trapezial bone are the scaphoid and trapezoid carpal bones and the second metacarpal bone.
The first carpometacarpal (trapeziometacarpal) joints are a frequent site of osteoarthritis in postmenopausal women. This osteoarthritis, which is typically bilateral both clinically and roentgenographically, may be mistaken for tenosynovitis unless its characteristic features are recognized.
Carpometacarpal osteoarthritis is a degenerative condition of the hand that causes pain, stiffness and weakness. It is the second most common site of degenerative disease in the hand after arthritis of the distal interphalangeal joints.
saddle jointThe carpometacarpal (CMC) of the thumb is a saddle joint that permits a wide range of motion and is largely responsible for the characteristic dexterity of human prehension. This joint, located at the very base of the thumb, is subject to large physical stresses throughout life.
Articulations. The carpometacarpal joints are made up of a number of bony articulations 1. The second to fifth carpometacarpal joints are synovial joints which commonly communicate with the intercarpal joints and the articulations at the metacarpal bases 1.
The base of the thumb where it meets the hand is called the carpometacarpal (CMC) joint. This joint allows the thumb to move freely in many directions. It also provides strength so the hand can grasp and grip. A smooth tissue called cartilage lines and cushions the bones of the CMC joint.
five jointsThe carpometacarpal joints (CMC) are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the fivemetacarpal bones. The CMC of the thumb or the first CMC, also known as the trapeziometacarpal joint (TMC), differs significantly from the other four CMCs.
The CMC joint (also called the basal joint) at the base of the thumb is commonly affected by arthritis. It is the thumb joint located deep in the heel of the palm where the thumb metacarpal joins with a wrist bone called the trapezium.
The CMC joint is located where the thumb (metacarpal) bone meets the wrist (carpal) bone.
Carpometacarpal Joint (CMC) The thumb CMC joint has the most freedom of motion. The thumb metacarpal can bend and extend the thumb, move the thumb away from and toward the hand, and spin the thumb on the trapezium.
Basal joint arthritis is the result of the wearing away of cartilage in the joint at the base of the thumb. That's why it is also known as thumb arthritis.
The 2022 edition of ICD-10-CM M18.1 became effective on October 1, 2021.
M18.1 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
M18 is a non-billable ICD-10 code for Osteoarthritis of first carpometacarpal joint. It should not be used for HIPAA-covered transactions as a more specific code is available to choose from below.
