Hi Guest 1!

Odynophagia (painful swallowing) currently falls under:

And yes, every medical claim/service you file requires at least 1 ICD-10 code. Typically, for biopsies, you will be using a benign or malignant neoplasm code, for example:

Moderate sedation services provided by the same physician or other qualified health care professional performing the diagnostic or therapeutic service that the sedation supports, requiring the presence of an independent trained observer to assist in the monitoring of the patient’s level of consciousness and physiological status; initial 15 minutes of intraservice time, patient age 5 years or older

For a suture, you may consider:

or:
you can use the CPT code below and include a narrative report describing the procedure:

41870 stands for: Periodontal mucosal grafting
21210 stands for: graft, bone; nasal, maxillary, or malar areas
21215 stands for: Graft, bone; mandible (includes obtaining graft)


As for:
D5283 - removable unilateral partial denture – one piece cast metal. (including clasps and teeth), mandibular
as well as Nesbit, Nesbit Insert/Adjus, Ozone Multiple Visit and Membrane Removal:

There are not direct CPT crosscodes available that we are aware of for these services, so you can either use the "D" code on the medical claim (many medical insurers will process the D code when the services are medically necessary and there is not a direct CPT crosscode available), or you use an unlisted/misc procedure code and include a narrative report describing the procedure, such as:
41899 - Unlisted procedure, dentoalveolar structures
40899 - Unlisted procedure, vestibule of mouth


Hope this helps!
