In simple words: This code refers to problems around the root of a tooth that happen after a root canal. It can cause pain, swelling, and trouble chewing. Doctors can diagnose it with x-rays and sometimes a biopsy. Treatment usually involves pain relievers, anti-inflammatory drugs, and muscle relaxants.

Periradicular pathology, a disease condition of the soft and bony tissue surrounding the roots of the teeth, develops due to previous endodontic, or root canal, treatment.It can manifest as inflammatory conditions with symptoms like pain, redness, heat, discomfort, swelling, and difficulty chewing. Diagnosis typically involves imaging techniques such as CT scans and biopsies of the affected soft tissues. Treatment may include analgesic medications, NSAIDs, and muscle relaxants.

Example 1: A patient presents with pain and swelling around a tooth that previously had a root canal. A CT scan reveals periradicular inflammation, and the code M27.5 is assigned., A patient experiences difficulty chewing after undergoing endodontic treatment. Upon examination, the dentist identifies signs of periradicular pathology, and M27.5 is used for billing., A patient reports discomfort and redness in the gums near a tooth that had a root canal several months prior. After ruling out other potential causes, the dentist diagnoses periradicular pathology and uses M27.5.

Documentation should include details of the previous endodontic treatment, the present symptoms, imaging findings (e.g., CT scan results), biopsy results (if performed), and the treatment plan.
