Hi Guest!
The diagnosis code(s) will depend on the patient's condition/symptoms - so in other words, why is the patient receiving the services?
For example, you may consider:
Z01.20 - Encounter for dental examination and cleaning without abnormal findings
Z01.21 - Encounter for dental examination and cleaning with abnormal findings
K02.3 - Arrested dental caries
K02.51 - Dental caries on pit and fissure surface limited to enamel
K02.52 - Dental caries on pit and fissure surface penetrating into dentin
K02.53 - Dental caries on pit and fissure surface penetrating into pulp
K02.61 - Dental caries on smooth surface limited to enamel
K02.62 - Dental caries on smooth surface penetrating into dentin
K02.63 - Dental caries on smooth surface penetrating into pulp
K02.7 - Dental root caries
K02.9 - Dental caries, unspecified
K03.89 - Other specified diseases of hard tissues of teeth
K04.1 - Necrosis of pulp
K04.2 - Pulp degeneration
K04.01 - Reversible pulpitis
K04.02 - Irreversible pulpitis
K05.211 - Aggressive periodontitis, localized, slight
K05.212 - Aggressive periodontitis, localized, moderate
K05.213 - Aggressive periodontitis, localized, severe
K05.219 - Aggressive periodontitis, localized, unspecified severity
K05.221 - Aggressive periodontitis, generalized, slight
K05.222 - Aggressive periodontitis, generalized, moderate
K05.223 - Aggressive periodontitis, generalized, severe
K05.229 - Aggressive periodontitis, generalized, unspecified severity
K05.311 - Chronic periodontitis, localized, slight
K05.312 - Chronic periodontitis, localized, moderate
K05.313 - Chronic periodontitis, localized, severe
K05.319 - Chronic periodontitis, localized, unspecified severity
K05.321 - Chronic periodontitis, generalized, slight
K05.322 - Chronic periodontitis, generalized, moderate
K05.323 - Chronic periodontitis, generalized, severe
K05.329 - Chronic periodontitis, generalized, unspecified severity
K05.10 - Chronic gingivitis, plaque induced
K05.11 - Chronic gingivitis, non-plaque induced
K08.89 - Other specified disorders of teeth and supporting structures
If you have additional details about the patient's condition, i'm happy to offer you some coding options.
Hope this helps!
