Chondromalacia patellae, left knee 1 M22.42 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 2 The 2020 edition of ICD-10-CM M22.42 became effective on October 1, 2019. 3 This is the American ICD-10-CM version of M22.42 - other international versions of ICD-10 M22.42 may differ.
This certainly creates a dilemma: Chondromalacia of the Patella (M22) is in the Code Set for Patellar Disorders, and therefore would be specific to the patella and not inclusive of Chondromalacia elsewhere in the joint. The M94.26 _ Code Set includes Chondromalacia of the Knee Joint, but not Chondromalacia of the Patella.
This is the American ICD-10-CM version of M94.26 - other international versions of ICD-10 M94.26 may differ. postprocedural chondropathies ( M96.-)
This is the American ICD-10-CM version of M22.4 - other international versions of ICD-10 M22.4 may differ. A degeneration of the articular cartilage of the patella, caused by a decrease in sulfated mucopolysaccharides in the ground substance. When accompanied by pain, it is sometimes considered part of or confused with patellofemoral pain syndrome.
Chondromalacia patella (knee pain) is the softening and breakdown of the tissue (cartilage) on the underside of the kneecap (patella). Pain results when the knee and the thigh bone (femur) rub together. Dull, aching pain and/or a feeling of grinding when the knee is flexed may occur.

Chondromalacia patella is the most common cause of chronic knee pain. Chondromalacia patella has also been called patellofemoral syndrome. The pain of chondromalacia patella is aggravated by activity or prolonged sitting with bent knees.
A condition called patellofemoral (PF) chondrosis describes cartilage loss on the surface of the kneecap. 2 Another term for the condition is chondromalacia, and its severity is graded on a scale from one to four.
Often called "runner's knee", chondromalacia patella is a common condition causing pain in the kneecap. The patella is covered with a layer of smooth cartilage, which normally glides across the knee when the joint is bent.

Chondrosis is the cartilage breakdown of the soft connective tissues in your joints. It happens due to excessive use, damage, and age factor. Commonly regarded as osteoarthritis, it usually attacks knees, hands, hips, neck, and lower backbone.

Chondromalacia patellae overlaps with the knee condition known as patellofemoral pain syndrome. This is a term used by doctors to describe pain at the front of the knee, which can be from various causes, but which does not seem to be due to a severe problem such as serious arthritis or injury.
7. Is chondromalacia patella the same as osteoarthritis? Yes, chondromalacia patella can be the same as either degenerative or traumatic osteoarthritis. This is because it involves an irreversible breakdown of the cartilage surface.
Chondromalacia patella describes early changes in the cartilage on the underside of the patella. If not effectively treated, these early changes may eventually lead to osteoarthritis in the knee joint where the kneecap and femur meet.

If you have chondromalacia of more than just the patella then code M94.621 will include the patella.
Learning this has made knee coding a lot easier because there are a lot of knee codes that have excludes 1 notes with each other, but you have them on different structures in the knee all the time, such as meniscus derangement and condyle derangement, or derangement and injuries in different compartments, and so on.
M22.4 _ is specific to Chondromalacia to he Patella, and only the Patella , and does not include any other Chondromalacia that may exist in the same joint. M94.26 _ applies to Chondromalacia of the Knee Joint other than the Patella (Exclusion1 Note). If the Knee Joint in question has both Chondromalacia of the Patella and Chondromalacia of other areas of the joint (Femoral Trochlea, Medial &/or Lateral Femoral Condyles &/or Medial &/or Tibial Plateaus), then I would recommend reporting both, particularly if there is an operative procedure that includes Chondroplasty of more than one of these joint areas.
ICD Book has it in writing. Follow the index. chondromalacia > Knee. M94.2- has an excludes 1 note for patella which means you cant code knee and patella together. If it's only the patella then you can report the M22.40.
The M94.26 _ Code Set includes Chondromalacia of the Knee Joint, but not Chondromalacia of the Patella. In spite of the Excludes 1 for M94.2, if the patient has both, and particularly if both are addressed at surgery, then I would still code both. The Excludes 1 for M94.2 should probably be an Excludes 2 Note, but the CMS will have to figure that out and solve the dilemma.#N#Alan Pechacek, M.D.
