more specific status. Z codes Z42 through Z51 are aftercare codes for which a secondary Z status code may be useful. In cases involving joint replacement surgery, a secondary Z status code should indicate which joint was replaced. For example, if you were treating a patient who had a total knee replacement, you would want to submit Z47.1, Aftercare
• Aftercare for injuries, during the healing and recovery phase, should be coded with the injury code and the appropriate 7th character for subsequent encounter rather than a Z code. • NOT reported if treatment is currently being directed at an acute disease or acute injury. Example: Return visit for unspecified fracture of the lower end
You would code the aftercare codes for follow up visits while the fracture is healing after the initial treatment. The guidelines state: "Fractures are coded using the aftercare codes for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.
Z47.89ICD-10-CM Code for Encounter for other orthopedic aftercare Z47. 89.
Presence of right artificial knee joint The 2022 edition of ICD-10-CM Z96. 651 became effective on October 1, 2021. This is the American ICD-10-CM version of Z96.
Z96. 651 - Presence of right artificial knee joint. ICD-10-CM.
652.
Total knee replacement is classified to code 81.54 and involves replacing the articular surfaces of the femoral condyles, tibial plateau, and patella.
Z96. 653 - Presence of artificial knee joint, bilateral. ICD-10-CM.
ICD-10: Z47. 1, Aftercare following surgery for joint replacement.
Aftercare codes are used only when the condition is under treatment or under healing phase after initial visit or treatment. Aftercare Z codes should not be reported when the treatment is for current or acute disease. Few exception are their, aftercare Z codes should not be reported for aftercare for injuries.
Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap.
ICD-10 code Z51. 89 for Encounter for other specified aftercare is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .

Also called: Knee arthroplasty. Knee replacement is surgery for people with severe knee damage. Knee replacement can relieve pain and allow you to be more active. Your doctor may recommend it if you have knee pain and medicine and other treatments are not helping you anymore.
During a hip replacement operation, the surgeon removes damaged cartilage and bone from your hip joint and replaces them with new, man-made parts.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including
The surgery can cause scarring, blood clots, and, rarely, infections. After a knee replacement, you will no longer be able to do certain activities, such as jogging and high-impact sports.
If other treatments such as physical therapy, pain medicines, and exercise haven't helped, hip replacement surgery might be an option for you .
For example, if you were treating a patient who had a total knee replacement, you would want to submit Z47.1, Aftercare following joint replacement surgery, as well as Z96.651 (to indicate that the joint replaced was the knee). Taking this one step further, let’s say the patient was receiving treatment for gait abnormality following a total knee replacement of the right knee due to osteoarthritis in that knee. Let’s also assume that, as a result of the surgery, the patient is no longer suffering from osteoarthritis. The appropriate codes for this scenario, according to this presentation, would be:
Remember, there are a number of orthopedic aftercare codes for specific surgeries—all of which you can find in the ICD-10 tabular list under Z47, Orthopedic aftercare.
If the line between acceptable and unacceptable uses of aftercare codes still seems a bit fuzzy, just remember that in most cases, you should only use aftercare codes if there’s no other way for you to express that a patient is on the “after” side of an aforementioned “before-and-after” event.
ICD-10 introduced the seventh character to streamline the way providers denote different encounter types—namely, those in volving active treatment versus those involving subsequent care. However, not all ICD-10 diagnosis codes include the option to add a seventh character. For example, most of the codes contained in chapter 13 of the tabular list (a.k.a. the musculoskeletal chapter) do not allow for seventh characters. And that makes sense considering that most of those codes represent conditions—including bone, joint, or muscle conditions that are recurrent or resulting from a healed injury—for which therapy treatment does progress in the same way it does for acute injuries.
You should add any comorbidities that may impact the rehab episode of care. You should not include osteoarthritis in the diagnostic set unless it affects other joints that will affect the episode." I hope that's helpful!
Z codes also apply to post-op care when the condition that precipitated the surgery no longer exists —but the patient still requires therapeutic care to return to a healthy level of function. In situations like these, ICD-10 provides a few coding options, including:
In situations where it’s appropriate to use Z codes, “aftercare codes are generally the first listed diagnosis,” Gray writes. However, that doesn’t mean the Z code should be the only diagnosis code listed for that patient.
