M94. 261 - Chondromalacia, right knee | ICD-10-CM.
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.
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.
562 Pain in left knee.
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 patella has also been called patellofemoral syndrome. The pain of chondromalacia patella is aggravated by activity or prolonged sitting with bent knees. Abnormal "tracking" allows the kneecap (patella) to grate over the lower end of the thighbone (femur), causing chronic inflammation and pain.
Chondromalacia patella, more commonly referred to as runners knee, is a condition where the cartilage along the underside of the kneecap begins to soften and deteriorates over time. When looking at the anatomy of the knee, the patella, or kneecap is designed to glide over a narrow groove on the top of the femur.
Patellofemoral arthritis refers to the presence of degenerative changes to the joint. Chondromalacia refers to degenerative changes in the articular cartilage of the patella that frequently precipitate the development of osteoarthritis.
The treatments can include rest, activity modification, physical therapy, stretching, bracing, injections, or arthroscopic surgery. Arthroscopic surgery for patellar chondromalacia involves placing instruments into the knee to shave down any unstable cartilage flaps on the patella and the trochlear groove.
An arthroscopy is the most common type of surgery performed for chondromalacia. Your physician may recommend arthroscopy to check the cartilage around your kneecap. If the cartilage is softened or shredded, the surgeon will remove those layers during the surgery.
Chondromalacia patella is rarely a severe condition. In fact, most people can manage it with rest, elevation, ice, and stretching. However, for some people, the condition can worsen to the point where pain cannot be managed with over-the-counter pain relievers and other at-home treatments.
Non-operative treatment is the usual treatment for this problem. You may require 4-6 weeks of Physical Therapy treatment, and then several more months of a home stretching and strengthening program to treat your chondromalacia patella. Getting the pain and inflammation under control is the first step.

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code M94.28 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.
In medicine, chondropathy refers to a disease of the cartilage. It is frequently divided into 5 grades, with 0-2 defined as normal, and 3-4 defined as diseased.

If you have chondromalacia of more than just the patella then code M94.621 will include the patella.
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.
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.
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.

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code M94.28 and a single ICD9 code, 733.92 is an approximate match for comparison and conversion purposes.
