Reader Question:

Tread Carefully with This Gastric Biopsy Diagnosis

Question: The provider performs gastric biopsy to identify focal erosion and prominent regenerative changes. Which ICD-10-CM codes do I report for this scenario?

Utah Subscriber

Answer: Given the above documentation, the appropriate ICD-10-CM diagnosis for focal erosion could have been K25.9 (Gastric ulcer, unspecified as acute or chronic, without hemorrhage or perforation). However, as there is no specific code for regeneration, so the most appropriate code would be K31.89 (Other diseases of stomach and duodenum).
