For UK private medical consultants
You're seeing the patients but not collecting what you're owed
Missed codes, insurer underpayments, and unreconciled follow-ups quietly erode revenue. For most private consultants, the gap can run to a meaningful share of net income every year, and it compounds because no one flags it.

Answer a few quick questions and see what your current billing gaps are likely costing you annually.

Paul, Solvable
- A consultant sees 8 patients in a clinic session but only bills for 6, missing two follow-up codes because the admin catch-up happens two weeks later.
- A clinic bills a standard consultation fee for an appointment that included a procedure, leaving the procedure code unbilled entirely.
- A hospital PMI contract has not been renegotiated in three years, meaning every insured admission is billed at rates 12–18% below current market.
- Revenue earned through clinical work is permanently lost unlike a denied claim, unbilled work cannot be recovered after time limits pass.
- Cash flow suffers as billing lags behind activity, creating a gap between cost and income.
- PMI relationships go unmanaged, with rates drifting below market while insurer profitability on your activity grows.
- Practice valuation is suppressed buyers and investors assess revenue based on what is billed, not what is delivered.
- Clinicians become demoralised when income does not reflect workload, without understanding why.
Providers without a revenue integrity programme lose 3–8% of net collectible revenue to undercoding, missed charges, and unrecovered denials, with initial denial rates at 11.8% in 2024 and payer audits rising 30% year-on-year in 2025. Studies estimate that 3–5% of hospital revenue is lost due to charge capture failures alone. Typically 3–7% of charges are missed entirely, resulting in unrecoverable revenue when no claim is ever generated. Healthcode processed 11.8 million PMI invoices in 2025, generating £7.5 billion for the UK private sector making accurate capture of every billable item a material financial issue at scale. Non-hospital private providers increased invoice volumes by an average of 8% in Q4 2025, meaning activity is growing faster than billing infrastructure in many independent practices.

Frequently asked questions
Why does this problem persist?
Billing is treated as an administrative afterthought clinicians focus on care and assume the invoicing takes care of itself, when in practice undercoding and missed charges accumulate quietly with no single moment of failure to trigger a review. Providers often focus only on denied claims, even though underpayments and missed charges can result in equal or higher revenue loss, meaning the real leakage never gets investigated. PMI insurer rules, procedure codes, and fee schedules are complex and change regularly, making it easy for busy practices to bill at outdated rates or miss billable add-on items without realising it.
What is the cost of leaving it unaddressed?
A practice billing £300,000 annually losing 5% to undercoding and missed charges is leaving £15,000 on the table every year with no marketing spend, no new patients, and no operational change required to recover it. At 8% leakage, that rises to £24,000. The revenue is already being earned; it simply is not being collected.
