Podiatry Coding & Billing Alert

Question: A diabetic patient presents to the office stating that she dropped a dirty kitchen knife on her right lesser toe, cutting the top of her toe two days ago. Her toe is now swollen, red, and painful and has a yellow discharge coming from it. The patient did not sustain damage to her toenail, and there was no foreign body in the wound. The podiatrist takes a culture of the laceration, and the result from the lab comes back as a staph infection. Which ICD-10 codes should I report on this claim?

Answer: You should report S91.114A (Laceration without foreign body of right lesser toe(s) without damage to nail, initial encounter) for the laceration along with the proper ICD-10 code such as B95.8 (Unspecified staphylococcus as the cause of diseases classified elsewhere) for the staph infection. You should also report W26.0XXA (Contact with knife, initial encounter) as the external cause code.
