K05.5 is a billable ICD-10 code used to specify a medical diagnosis of other periodontal diseases. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Developmental anomaly of periodontal tissue
- Gingival pocket
- Injury of periodontal tissue
- Intrabony periodontal defect
- Necrotizing periodontal disease
- Necrotizing ulcerative periodontitis
- Periodontal and endodontic lesion
- Periodontal ligament strain
- Periodontal pocket
- Thickened dental follicle
- Widened periodontal ligament space
- Periodontal Diseases-. pathological processes involving the periodontium including the gum (gingiva), the alveolar bone (alveolar process), the dental cementum, and the periodontal ligament.
- Gingival Pocket-. an abnormal extension of a gingival sulcus not accompanied by the apical migration of the epithelial attachment.
- Periodontal Debridement-. removal or disruption of dental deposits and plaque-retentive dental calculus from tooth surfaces and within the periodontal pocket space without deliberate removal of cementum as done in root planing and often in dental scaling. the goal is to conserve dental cementum to help maintain or re-establish healthy periodontal environment and eliminate periodontitis by using light instrumentation strokes and nonsurgical techniques (e.g., ultrasonic, laser instruments).
- Periodontal Pocket-. an abnormal extension of a gingival sulcus accompanied by the apical migration of the epithelial attachment and bone resorption.
- Gingival Pocket-. an abnormal deepening of a gingival sulcus not associated with destruction of the supporting periodontal tissue.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Combined periodontic-endodontic lesion
- Narrow gingival width (of periodontal soft tissue)
Type 2 ExcludesType 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- leukoplakia of gingiva K13.21
Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:

If you have gum disease, you're not alone. Many U.S. adults currently have some form of the disease. It ranges from simple gum inflammation, called gingivitis, to serious damage to the tissue and bone supporting the teeth. In the worst cases, you can lose teeth.
In gingivitis, the gums become red and swollen. They can bleed easily. Gingivitis is a mild form of gum disease. You can usually reverse it with daily brushing and flossing and regular cleanings by a dentist or dental hygienist. Untreated gingivitis can lead to periodontitis. If you have periodontitis, the gums pull away from the teeth and form pockets that become infected. If not treated, the bones, gums and connective tissue that support the teeth are destroyed.
