OPD and IPD are two different worlds of billing, and a consultant fee schedule that treats them the same will frustrate everyone. Outpatient work is high-volume, low-value, and fast; inpatient work is lower-volume, higher-value, and spread across multiple days and interventions. Structuring consultant fees that work means designing for both realities deliberately, rather than bolting one onto the other.
How OPD and IPD billing differ
The differences are not cosmetic; they shape how fees should be calculated, when they should be paid, and how disputes arise. Understanding the contrast is the foundation of a fee schedule that fits each setting.
- OPD: many short consultations, small per-visit fees, immediate collection, fast turnover.
- IPD: fewer patients but multiple visits per admission, larger fees, collection spread across the stay.
- OPD fees are typically per consultation; IPD fees may be per-visit, per-day, or tied to the procedure.
- IPD involves more parties (admitting consultant, specialists, surgeons) sharing one episode.
Structuring OPD fees
OPD lends itself to a simple, fixed per-consultation fee. Volume is high and amounts are small, so predictability beats precision; a flat fee per visit is easy for the consultant to anticipate and for the hospital to administer. The main control is accurate visit capture: at OPD volumes, a few uncounted consultations a day add up to meaningful unbilled fees over a month.
Structuring IPD fees
IPD is more nuanced. A single admission may involve daily rounds by the admitting consultant, reviews by specialists, and a procedure or surgery. The fee schedule must define how each of these is paid, whether per visit, per day, or per procedure, and how the components combine. Because collection is spread across the stay and final settlement, percentage or hybrid models need clear rules about when the fee crystallises.
For IPD, define exactly when a consultant's fee is earned: at each visit, at discharge, or at final collection. Ambiguity here is the leading cause of inpatient fee disputes, because the patient's stay and payment unfold over days.
Handling multiple consultants on one admission
A complex inpatient case may touch several consultants: the admitting physician, a cardiologist, a surgeon, an anaesthetist. Each has a legitimate claim on a portion of the episode's fees. The schedule must attribute each visit and procedure to the right consultant so that fees, collections, and TDS all map cleanly to individuals rather than getting lost in a single admission total.
TDS treatment is the same; sequencing is not
Whether a fee is OPD or IPD, it is professional fees under Section 194J, so 10% TDS applies once a consultant crosses ₹30,000 for the year. What differs is sequencing: OPD fees are easy to compute and deduct at the point of the visit, while IPD percentage fees may need the admission's collection to be finalised before the fee, and the TDS on it, can be calculated. Build that timing into your payout cycle.
- Use simple fixed per-consultation fees for high-volume OPD.
- Define IPD fees precisely: per visit, per day, or per procedure.
- State exactly when an IPD fee is earned and payable.
- Attribute every visit and procedure to the correct consultant.
- Sequence TDS to follow collection where percentage models apply.
OPD billing rewards speed and accurate counting; IPD billing rewards clear rules about who earned what, and when. A fee schedule that respects both is one that nobody argues with.
Bringing it together
A consultant fee schedule that works is not one schedule; it is two well-designed ones living under a single transparent system. Keep OPD simple and high-throughput, make IPD precise and clearly sequenced, attribute every event to the right consultant, and let TDS follow the money correctly. Do that, and both the fast outpatient flow and the complex inpatient episode settle cleanly.
