Tooth Extraction ICD-10

Accurate coding is essential for successful dental claims

For South African dentists submitting claims for tooth extraction, the correct use of diagnosis codes (ICD‑10) paired with clear documentation and the medical aid scheme’s procedure codes determines whether a claim will be paid. This article explains practical guidance for “tooth extraction ICD 10” so you can reduce rejections and speed reimbursements.

Why ICD‑10 matters for tooth extraction claims ICD‑10 codes are diagnosis codes – they tell the medical aid why a procedure (like an extraction) was clinically necessary. Medical aid schemes review the ICD‑10 diagnosis together with the dental procedure code, clinical notes, and radiographs. Using a diagnosis code that accurately reflects the reason for extraction (caries, infection, impaction, trauma, etc.) helps claims processors accept the clinical necessity of the procedure.

Common ICD‑10 diagnosis groups used for extractions ICD‑10 classifies oral disease under the K00–K14 range. For tooth extraction claims you’ll commonly select one of these diagnosis categories based on the clinical finding:

• K02 – Dental caries: Use when extraction is due to extensive decay that cannot be restored.
• K04 – Diseases of pulp and periapical tissues: Use for extractions driven by pulpal necrosis, acute apical periodontitis, or periapical abscess.
• K01 – Disorders of tooth development and eruption: Use when extracting impacted or malerupted teeth.
• K08 – Other disorders of teeth and supporting structures: Use for retained roots, fracture, or other conditions leading to extraction.

Note: Use the most specific ICD‑10 subcategory available in your system (e.g., K04.x) if you can confidently document the precise diagnosis. Specificity reduces queries from medical aids.

What medical aids typically expect on a tooth extraction claim

To avoid denials, include the following on every extraction claim:

1. Correct ICD‑10 diagnosis code(s) – match the reason for extraction to the K00–K14 group.
2. Procedure code(s) – use the dental tariff or procedure coding system required by the medical aid (e.g., the insurer’s preferred code set). ICD‑10 is not a substitute for a procedure code.
3. Tooth notation – indicate the tooth number using FDI notation (recommended) or the notation requested by the payer.
4. Clinical notes – succinct rationale: symptoms, diagnosis, alternatives considered, and reason extraction was necessary.
5. Radiographs – current pre‑operative images supporting the diagnosis (e.g., periapical radiograph showing periapical pathology or impaction).
6. Anaesthesia and surgical details – type of anaesthesia, surgical vs. simple extraction, extra time or complexity if applicable.
7. Pre‑authorization when required – for some major or surgical extractions, insurers require pre‑authorisation. Obtain written approval where needed.

Best practice workflow for an unambiguous claim

• Diagnose and document: note clinical findings, pulp/periapical status, mobility, swelling, sinus tract, prior treatment attempts.
• Match the diagnosis to the correct ICD‑10 category (K02, K04, K01, K08, etc.). Use the most specific subcode you can support clinically.
• Use the medical aids’s procedure/tariff code for the extraction type and list the tooth number.
• Attach the radiograph and brief clinical narrative.
• Submit pre‑authorisation if required, especially for surgical or complicated removals.
• Follow up promptly if the medical aid requests additional information.

Common reasons extractions claims are queried or denied

• Vague or incorrect ICD‑10 code that doesn’t support extraction (e.g., using a generic code rather than specifying infection or impaction).
• Missing radiographs or inadequate clinical justification.
• Wrong tooth notation or mismatch between procedure tooth and radiograph.
• Failure to obtain pre‑authorisation for surgical extractions.
• Use of procedure codes the payer does not accept without mapping to their tariff.

Practical tips to reduce rejections

• Keep a short diagnosis template in the clinical notes that aligns with ICD‑10 language (e.g., “Periapical radiolucency at tooth 36 consistent with chronic apical periodontitis – extraction indicated” – then use the K04.x code).
• Confirm the medical aid’s preferred coding format and whether they require additional codes (e.g., Z codes for history).
• Train staff to verify tooth numbering, attach radiographs, and check authorisation rules before submission.
• When in doubt, contact the medical aid’s provider helpdesk before performing non‑emergency extractions.

Final checklist before you submit

• Specific ICD‑10 diagnosis code matching the clinical reason (K02 / K04 / K01 / K08).
• Correct procedure/tariff code and tooth number.
• Radiograph(s) attached.
• Short clinical rationale and operative details.
• Pre‑authorisation if required.
