Is there a dx code for False Positive Lymes Disease? I cant find any guidelines on this. I told the physcian to code signs and symptoms.

Coding example: Mr. E. is being treated for Lyme disease caused by a deer tick bite. He is experiencing pain and immobility in his knee. Upon consultation with an orthopedic surgeon, he was diagnosed with arthritis of the knee which is common with Lyme disease. For this patient, list the following etiology/manifestation pair:
Etiology: 088.81 (Lyme disease)
Manifestation: 711.86 (Arthropathy associated with other infectious and parasitic diseases; lower leg).
When you look up "arthritis, due to or associated with Lyme disease" in the alphabetic index, you’ll see "088.81 [711.8]." Checking these codes against the tabular list, you’ll see the note "Code first underlying disease as: diseases classified to 080-088, 100-104, 130-136" following 711.8. You’ll also see that this code requires a fifth digit to indicate the location of the arthritis.
There are also manifestation codes that appear in the alphabetic index but do not follow the usual format, Usher says. When you locate these etiology codes, you won’t find them beside a corresponding manifestation in italic print.
Instead, look up the manifestation and then look for words such as due to, with, associated with, or in to find the right code. For example, "Arthritis Due to or Associated With."
