ICD-10-CM Code K05.4
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
K05.4 is a billable ICD code used to specify a diagnosis of periodontosis. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code K054 is used to code Periodontitis
Periodontitis, also known as pyorrhea, is a set of inflammatory diseases affecting the periodontium, i.e., the tissues that surround and support the teeth. Periodontitis involves progressive loss of the alveolar bone around the teeth, and if left untreated, can lead to the loosening and subsequent loss of teeth. Periodontitis is caused by microorganisms that adhere to and grow on the tooth's surfaces, along with an over-aggressive immune response against these microorganisms. A diagnosis of periodontitis is established by inspecting the soft gum tissues around the teeth with a probe (i.e., a clinical examination) and by evaluating the patient's X-ray films (i.e. a radiographic examination), to determine the amount of bone loss around the teeth. Specialists in the treatment of periodontitis are periodontists; their field is known as "periodontology" or "periodontics".
This radiograph shows significant bone loss between the two roots of a tooth (black region). The spongy bone has receded due to infection under tooth, reducing the bony support for the tooth.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 523.5 was previously used, K05.4 is the appropriate modern ICD10 code.
