Amazing Coding tips for Osteoarthritis ICD 10 code

There are many ICD codes, which appears to be easy to code but difficult to code. I have generally come up with many of such diagnosis codes. For example, status codes, V codes that are now replaced by Z codes of ICD 10, are used to be very clear to understand but to find the correct code was always difficult. The reason I am here again to discuss about the how to code a joint disease, Osteoarthritis. The ICD 9 code for Osteoarthritis is very direct in codebooks. But, still few coders are unable to find the correct diagnosis code for this joint disease. Osteoarthritis ICD 10 codes varies for all the joints from head to toe. Let us first checkout first more about the osteoarthritis and it diagnosis coding in ICD 9 CM as well as in ICD 10 CM.

Basics about Osteoarthritis ICD 10 code

Osteoarthritis is a joint disease caused by aging, injury or obesity. The most common symptoms for osteoarthritis are joint pain and stiffness. Therefore, coding Osteoarthritis is not much different from coding joint pain. I have already shared how we have code ICD 10 CM code for Knee pain in my previous post. As I have mentioned earlier, the ICD 10 code varies for each joint, so let us first checkout the different ICD 9 CM for Osteoarthritis of each joint.

715.91 – shoulder

 715.92 – Upper arm (elbow)

715.93 – Lower arm (wrist)

715.94 – Hand

715.95 – Pelvic region and thigh (hip)

715.96 – Lower leg (Knee)

715.97 – ankle and foot

715.90 – site, unspecified

Now, the above list of ICD 9 codes for osteoarthritis is to be used only when they have documented osteoarthritis. There are similar ICD 9 codes for localized (715.1X, 715.2X and 715.3X)  and generalized (715.0X) osteoarthritis, which should be used only when there is clear documentation of localized and generalized osteoarthritis of joint.

Documentation for ICD 10 code for Osteoarthritis

The documentation can have different names for osteoarthritis in the medical report. I being a medical coder, have come across phrases like degenerative changes of joint, degenerative joint disease, tricompartmental osteoarthritis, OA disease etc. which will be documented in the medical report to denote osteoarthritis. Hence, you should be careful while coding osteoarthritis ICD 10 CM code.

ICD 10 codes for Osteoarthritis

ICD codes are very different from ICD 9 CM codes. In ICD 10, the specificity of diagnosis codes increases too much. For example, as we seen we have only one code for Knee osteoarthritis, 719.46 in ICD 9 CM, but we have 4 different ICD 10 CM for the same code. Below are the four ICD 10 codes for knee osteoarthritis.

M17.0 – Bilateral primary osteoarthritis of knee

M17.10 – Unilateral primary osteoarthritis, unspecified knee

M17.11 – Unilateral primary osteoarthritis, right knee

M17.12 – Unilateral primary osteoarthritis, left knee

If you can see the above ICD 10 codes, you can easily find out, how specific these codes are. Just a difference of single digit in each code gives more information about the diagnosis. In ICD 10 we have separate code for unilateral and bilateral side for diagnosis like osteoarthritis in ICD 10 codes. ICD 9 code for osteoarthritis would not be as specific as ICD 10, but all diagnoses are correct as per ICD coding guidelines. Hope, now you can code osteoarthritis diagnosis is both ICD 9 CM and ICD 10 CM comfortably.

Other list of ICD 10 code for Osteoarthritis

There are many codes for other specific diagnosis of osteoarthritis. Below you find a list of ICD 10 codes used for osteoarthritis which are used in across all the facilities in medical coding.
