Other disorders of cartilage (M94)

The M94 ICD-10 codes categorize various other disorders of cartilage, providing specific codes for conditions affecting the cartilage in different body locations. These codes cover diseases like Tietze's disease, relapsing polychondritis, chondromalacia, and chondrolysis, each with subcodes identifying affected areas such as the shoulder, knee, or hip.

This section helps medical coders and healthcare professionals accurately document less common cartilage disorders. For example, M94.0 applies to Tietze's disease (also known as costal chondritis), a condition causing chest cartilage inflammation. M94.1 codes relapsing polychondritis, an autoimmune condition affecting cartilage in the larynx and other sites. Chondromalacia, or softening of cartilage, has multiple codes like M94.21 (shoulder) and M94.26 (knee), useful for pinpointing the exact joint involved. Additionally, M94.3 relates to chondrolysis, which is cartilage breakdown, notably around the hip. Unspecified or multiple-site cartilage disorders fall under codes like M94.9 or M94.8X9. Understanding these codes assists in identifying the correct ICD-10 code for cartilage-related conditions during clinical documentation and billing.
