Follow Coding Steps for Neuropathy With Underlying Disease
Question: Encounter notes indicate a patient suffers from autonomic neuropathy caused by drug-induced gout of the left shoulder. What diagnosis code(s) should I report for this patient? AAPC Forum Participant Answer: You’ll need a pair of ICD-10-CM codes for this patient, and the order of the diagnosis codes will matter. On your claim, first report M10.212 (Drug-induced gout, left shoulder) to represent the patient’s gout. Then, report G99.0 (Autonomic neuropathy in diseases classified elsewhere) for the autonomic neuropathy. The Code also notes beneath the descriptor for G99.0 make it clear you should report any disease that is affecting the gout. The notes read: “Code first underlying disease, such as: amyloidosis (E85.-); gout (M1A.-, M10.-); hyperthyroidism (E05.-).” There is also an important exclusion note beneath G99.0 that you should mind when coding: “Excludes1: diabetic autonomic neuropathy (E08-E13 with .43).” Chris Boucher, MS, CPC, Senior Development Editor, AAPC
