Hello all! This is my first post so please be gentle . I received an EOB for 2 medicare patients with co151 denial code. I am well versed on medicare visit limits and we are sure to stay within those guidelines so I am perplexed as to why they denied. On the first patient, who has had 11 visits we billed codes 98940 AT, G8730 & G8942, one dos. The second patient has had 12 visits with one set of dx's and 4 visits under a second set of dx's. Both containing sciatica. Any help is appreciated!
