What is medical code 80050?

Medical code 80050 refers to "Arthrodesis, interphalangeal joint(s) of single digit, any type, each joint." This code is used in medical billing and documentation to indicate the surgical fusion of one or more interphalangeal joints (the joints between the small bones of the fingers or toes) within a single digit. The procedure involves creating a permanent union between the bones to correct misalignment, instability, or severe arthritis. The code includes all types of arthrodesis techniques, such as bone grafting, internal fixation, or external fixation. The code "each joint" specifies that the code should be billed separately for each individual joint that undergoes arthrodesis.
