NHS dental claiming in England runs on the FP17 form submitted to the NHS Business Services Authority (NHSBSA) through WebEDI. Claims must be submitted within 2 months of treatment completion. Miss that window and the UDAs are disallowed entirely — not delayed, not recoverable. For mixed NHS/private practices, the billing workflow is further complicated by the need to track two separate income streams against different performance metrics and patient records.
NHS dental practices operate on a Unit of Dental Activity (UDA) contract. The practice receives an annual UDA target from NHS England and must deliver between 96% and 102% of that target. Underdelivery triggers contract value clawback; significant overdelivery is not paid at the same rate and can indicate contract management issues.
Different treatments earn different UDA values:
| Band | UDAs | Treatment type |
|---|---|---|
| Band 1 | 1 UDA | Examination, X-ray, scale and polish — prevention and screening |
| Band 2a | 3 UDAs | Simple treatment including fillings (1–2), extractions, or simple treatment not covered in Band 1 |
| Band 2b | 5 UDAs | Endodontics, or 3 or more fillings/extractions |
| Band 2c | 7 UDAs | Molar endodontics (root canal on a molar tooth) |
| Band 3 | 12 UDAs | Complex treatment: crowns, bridges, dentures |
The band assigned to a course of treatment must reflect the most complex treatment provided. A patient who attends for an examination (Band 1) and then returns for a filling within the same course of treatment has a Band 2a or higher claim, not two separate Band 1 claims. Software that does not handle course of treatment correctly can generate claims that NHSBSA will query or reject.
NHSBSA updated the FP17 mandatory data requirements in October 2022. Practices still failing to complete the additional fields will have claims rejected. The new mandatory fields are:
Practice management software should prompt for these fields at claim creation and should not allow submission without them populated. If your current system does not do this, claims submitted without mandatory fields will be returned as incomplete.
The 2-month submission rule is not a soft guideline. Claims submitted after 2 months of treatment completion are marked as "Late Submitted Claim" by NHSBSA and the associated UDAs are disallowed entirely. There is no appeal mechanism for genuine lateness — the UDAs are simply lost from the contract year's count.
For practices running close to their UDA target, a batch of late claims at year-end can push delivery below 96%, triggering clawback. Software that tracks submission status per course of treatment and flags approaching 2-month deadlines prevents this.
Mixed NHS/private practices need to track two entirely different billing workflows. NHS claims go to NHSBSA via WebEDI in exchange for UDA payment. Private treatment is invoiced directly to the patient or through a dental plan administrator. The two streams must be kept separate in the clinical records and accounts — NHSBSA audits check that treatments billed as NHS are not also being charged to patients privately.
Specialist software like Pearl Dental focuses specifically on managing mixed workflows, helping practices hit their UDA targets while identifying where private income opportunities exist within the existing patient base. For practices where the NHS contract is not generating sufficient income relative to the UDA commitment, software that surfaces this data clearly per dentist and per treatment category enables informed decisions about contract renegotiation or private growth.
