SOP Bulletin 166

ICD Coding:
  • ICD-9-CM Codes: 101, 523.0, 523.1
  • ICD-10-AM Codes: A69.1, K05.0, K05.1

This is inflammation of the gums (also known as the gingiva). This SOP does not extend to inflammation of the deeper supporting structures of the tooth, which is covered by the SOP for periodontitis.

Is specific diagnostic evidence required to apply the SOP?No.

The relevant medical specialist is a dentist or oral surgeon.

Are there sub-factors that require specific information? – Yes.

Smoking and nutritional deficiency factors apply to acute necrotising ulcerative gingivitis only, so information on whether this type of gingivitis is present may be needed. However, this condition is very unlikely to be present.

Additional diagnoses covered by SOP
  • Acute gingivitis
  • Acute necrotising ulcerative gingivitis, also known as trench mouth or Vincent’s gingivitis
  • Chronic gingivitis
  • Desquamative gingivitis

  • Peri-implant mucositis
  • Plasma cell gingivitis

  1. seek medical officer advice about further investigation, or;
