So, for pseudogout of the L knee, I would use dx code M11. 262.
Non-gout crystal arthropathy (ICD-10 codes M11. 0–M11. 9) was subclassified in four different groups: calcium pyrophosphate crystal deposition related arthropathy (CPPD), unspecified non-gout arthropathies, chondrocalcinosis, and hydroxyapatite crystal deposition disease.
Other specified crystal arthropathies, unspecified site The 2022 edition of ICD-10-CM M11. 80 became effective on October 1, 2021. This is the American ICD-10-CM version of M11.
Other chondrocalcinosis, right knee The 2022 edition of ICD-10-CM M11. 261 became effective on October 1, 2021. This is the American ICD-10-CM version of M11.
262 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 M11. 262 became effective on October 1, 2021.
Gout and pseudogout, while both joint problems caused by crystals, are caused by different kinds of crystals. Gout is caused by sodium urate crystals and pseudogout is caused by calcium pyrophosphate crystals.
Also called calcium pyrophosphate deposition disease or CPPD, the common term "pseudogout" was coined for the condition's similarity to gout. Crystal deposits within a joint cause both conditions, although the type of crystal differs for each condition.
Chondrocalcinosis, also known as calcium pyrophosphate deposition (CPPD) and pseudogout, is a condition where calcium pyrophosphate crystals build up in the joints. It is a type of arthritis that causes inflammation, stiffness, tenderness, redness, and warmth of the joints.
Calcium pyrophosphate deposition (CPPD) disease, commonly called “pseudogout,” is a painful form of arthritis that comes on suddenly. It occurs when calcium pyrophosphate crystals sit in the joint and surrounding tissues and cause symptoms like gout. Gout, however, is caused by a different type of crystal.
M17. 12, unilateral primary osteoarthritis, left knee.
Pseudogout (or "false gout") is a form of arthritis that results from deposits of calcium pyrophosphate crystals (its medical term is calcium pyrophosphate dihydrate crystal deposition disease, or CPPD). It commonly affects the knees and wrists.
Code M10. 9 is the diagnosis code used for Gout, Unspecified. It is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints and occurs when uric acid builds up in your blood.
