Other chondrocalcinosis, left hip

This diagnosis code signifies the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, also known as pseudogout, affecting the left hip joint. It indicates a form of arthritis caused by these crystals, leading to inflammation and joint damage.

Apply this code when documentation explicitly states "chondrocalcinosis" or "CPPD deposition disease" affecting the left hip, and the condition is not specified as familial, post-traumatic, or due to another metabolic or acquired disorder. This code is appropriate for idiopathic or unspecified forms of chondrocalcinosis of the left hip.

• Ensure the documentation clearly specifies the left hip; laterality is crucial for accurate coding.
• Distinguish from gout (M10.-) which involves uric acid crystals, not CPPD crystals.
• If the chondrocalcinosis is secondary to a metabolic disorder (e.g., hemochromatosis, hyperparathyroidism), code the underlying condition first, followed by the appropriate M11.1- code.
