Nurse practitioner students learn to write both a history and physical and a SOAP note, often in the same semester, and then spend their first clinical months unsure which one a given encounter calls for. The confusion is understandable because the two documents overlap in content and share the same clinical purpose. But they are not interchangeable, and choosing the wrong one has consequences that reach past the chart into billing, medical necessity, and the defensibility of the record. This guide draws a clear distinction, shows what each document contains, and explains why the choice matters more than most students are told.
The short version is that the history and physical is the comprehensive, foundational document you write once at the start of a care relationship, and the SOAP note is the focused, interval document you write at every visit after. Getting the match right depends on the encounter type, and getting it wrong results in either a bloated note that invites audit scrutiny or a thin note that fails to support the level of service billed. If your program is asking you to master clinical documentation and you want structured feedback on your notes, our SOAP note and clinical documentation support is built for exactly that.
Quick Answer:
Write a history and physical (H&P) for a new patient, a hospital admission, or a pre-procedure evaluation. It is the complete, foundational assessment, with a full history, a comprehensive review of systems, and a complete physical examination. Write a SOAP note (progress note) for follow-up and ongoing visits: it is focused, updating the record on interval change without repeating a comprehensive assessment of every prior problem. The two are not stylistic choices; encounter type decides which is appropriate. The choice also affects reimbursement because documentation must support the medical necessity and the level of service billed. Under the 2021 office-visit E/M rules, that level is set by medical decision making or total time, not by how much history and exam you record, so padding a note no longer raises its level, and cloning a prior note to save time can trigger denials.
Two Documents, One Lineage
Both documents descend from the same source. Lawrence Weed introduced the problem-oriented medical record in the 1960s, and his framework, laid out in a two-part New England Journal of Medicine paper in 1968, gave clinical documentation its enduring logic: organize the record around the patient's problems, and structure each note so that reasoning is visible rather than buried (Weed, 1968). The SOAP note is the progress-note format that populates the record, with its four sections of Subjective, Objective, Assessment, and Plan (Podder et al., StatPearls). The H&P is the comprehensive entry that opens the record before the progress notes begin.
Understanding that shared lineage helps explain why the two look similar. Both move from the patient's story to the clinician's findings to an assessment and a plan. The difference is not in the logic but in the scope and the moment of use.
The History and Physical: The Foundational Document
The H&P is the most complete assessment in the chart. You write it when you are establishing the clinical picture from the ground up, at a first visit with a new patient, on admission to the hospital, or before a procedure that requires a full evaluation. Because it is foundational, it is expansive. A full H&P includes the chief complaint and history of present illness; a complete past medical and surgical history; family and social history; current medications and allergies; a full review of systems; and a complete physical examination, followed by the assessment and plan.
The purpose of that breadth is to create a baseline. Everything documented later, every progress note, every change in the plan, references the picture the H&P establishes. A hospital admission H&P is a formal requirement, not an option, and the same comprehensive assessment is expected when a new patient enters a practice. This is the document that answers the question, " Who is this patient, and what is the full context of their care, and it answers it once, thoroughly.
The SOAP Note: The Focused Interval Document
The SOAP note is what you write at every encounter after the foundation is laid. It is deliberately focused. Rather than reassessing the entire patient, it captures what has changed since the last visit and addresses the problem or problems at hand. A comprehensive review of all prior medical problems is generally not required in a progress note; the note concentrates on the interval, the active problems, and the clinical reasoning that connects them.
Its four sections carry that focus. The Subjective section records the patient's own account since the last visit: symptoms, adherence, and response to treatment. The Objective section holds measurable and observed data from this encounter, vital signs, the focused physical examination, and relevant results. The Assessment is the clinician's diagnostic synthesis, the working diagnosis, and the reasoning that ties the subjective and objective findings together, which is a point students frequently misplace and one we cover in depth in our companion guide on what the assessment section actually means. The Plan sets out what happens next: medications, testing, referrals, patient education, and the follow-up interval.
The SOAP note's economy is a feature, not a shortcut. A focused progress note that addresses the active problem with clear reasoning is doing exactly what it should. The skill lies in deciding what belongs in the interval and what does not.
Table 1: History and Physical vs SOAP Progress Note
Feature | History and Physical (H&P) | SOAP Progress Note |
|---|---|---|
When it is written | New patient, hospital admission, pre-procedure evaluation | Follow-up and ongoing visits after the baseline is set |
Scope | Comprehensive; establishes the full clinical baseline | Focused; captures interval change and active problems |
History | Full past medical, surgical, family, social history and medications | Interval history since the last visit (Subjective) |
Review of systems | Complete, multi-system | Pertinent to the presenting problem |
Physical examination | Complete examination (objective) | Focused examination for the encounter (Objective) |
Primary purpose | Create the baseline the rest of the record references | Document reasoning and change at this visit |
Documentation caution | Must be genuinely comprehensive, not a template dump | Must stand on its own; never a cloned copy-forward |
Where the Choice Becomes a Billing Problem
Here is the part most documentation tutorials leave out, and it is where an academic point becomes a professional one. The choice between comprehensive and focused documentation directly affects reimbursement, and the rules changed in ways that many students were never taught.
Before 2021, the level of an office visit was driven in part by how much history and physical examination the clinician documented, which created an incentive to record more. That incentive is gone. Effective January 1, 2021, for office and outpatient evaluation and management codes 99202 through 99215, the level of service is selected based on the level of medical decision-making or the total time spent on the date of the encounter. History and examination must still be performed and documented as medically appropriate, but they no longer determine the code level, and the lowest new-patient code, 99201, was deleted entirely (American College of Surgeons). The four levels of medical decision making, straightforward, low, moderate, and high, carry the weight now.
The practical consequence for documentation is a reversal of the old habit. Padding a note with an exhaustive review of systems no longer raises the billable level, because the level follows the complexity of the decision-making or the time, not the volume of recorded history. A focused SOAP note that clearly conveys the complexity of the clinical decision can support the appropriate level on its own. Writing a full H&P for a routine follow-up does not earn a higher payment; it simply produces a longer note that must still be justified by medical necessity.
Medical Necessity, and the Trap of the Cloned Note
Medical necessity is the overarching standard for payment. The Social Security Act, at section 1862(a)(1)(A), bars payment for services that are not reasonable and necessary for the diagnosis or treatment of illness or injury, and every note ultimately has to support that standard. A note can be complete, with every field populated, and still fail if it does not connect the service to the patient's condition and support the level billed.
This is where the modern documentation trap sits. Electronic records make it easy to copy a prior note forward, update a line, and move on. The habit is understandable under time pressure, and it is a serious liability. Cloned documentation, entries worded the same as or similar to previous ones, is treated by Medicare administrative contractors as a misrepresentation of the medical necessity requirement for coverage, and identification of cloned notes can lead to denial of services and recoupment of overpayments (AAPC). The scale of the habit is striking: one study of progress notes published in the Journal of the American Medical Association found that only about 18 percent of the text in the notes examined had been newly entered by the clinician, with the rest copied or imported (Wang et al., 2017).
The lesson for an NP student is direct. Each note has to stand on its own as a specific record of a specific encounter. A focused SOAP note written fresh is safer and more defensible than a comprehensive-looking note assembled by carrying forward yesterday's text. The document that reflects genuine clinical reasoning about this visit is the one that survives review.

Choosing Correctly, Every Time
The decision is not difficult once the principle is clear. Ask what the encounter is. If you are meeting a patient for the first time, admitting them, or evaluating them before a procedure, you are building the foundation, and that calls for the comprehensive H&P. If you are seeing an established patient for follow-up or ongoing management, you are updating the foundation, and that calls for the focused SOAP note. The content of each follows from its purpose: breadth and baseline for the H&P, interval, and active problems for the SOAP note.
For students carrying a clinical documentation requirement into a capstone or scholarly project, the same discipline that produces a clean note also produces a defensible project, and our DNP project support and MSN capstone guidance extend that rigor from the chart to the deliverable. The reasoning skills that hold a good note together, frame a problem, and defend an assessment are the same ones that anchor a strong PICOT question, which we walk through in our guide on building a focused PICOT question. And the diagnostic precision of a good assessment line connects directly to formal nursing diagnosis work, as covered in our piece on the NANDA-I PES format.
Frequently Asked Questions
What is the main difference between an H&P and a SOAP note?
Scope and timing. The history and physical is the comprehensive, foundational document written once, at a new-patient visit, a hospital admission, or before a procedure, and it includes a full history, a complete review of systems, and a complete physical examination. The SOAP note is the focused progress note written at follow-up and ongoing visits, capturing interval change and the active problems without reassessing every prior issue. The H&P builds the baseline; the SOAP note updates it.
When is an H&P required rather than a SOAP note?
An H&P is expected whenever you are establishing the clinical picture from scratch. That means a new patient entering a practice, an admission to the hospital, and a pre-procedure evaluation. Hospital admission H&Ps are a formal documentation requirement. For every subsequent encounter with an established patient in which you are managing known problems and recording interval changes, the focused SOAP progress note is the appropriate document.
Does writing a longer, more detailed note increase reimbursement?
No, not for office and outpatient visits under the current rules. Since January 1, 2021, the level of service for codes 99202 through 99215 is determined by medical decision-making or total time, rather than by the volume of the history and physical examination documented. History and exam must still be documented as medically appropriate, but recording more of them does not raise the billable level. A focused note that conveys the complexity of the clinical decision can support the correct level without padding.
Why is copying a previous note forward risky?
Because it can produce cloned documentation, which Medicare administrative contractors treat as a misrepresentation of medical necessity. When entries are worded the same as or similar to previous ones, or similar from patient to patient, the record no longer demonstrates that each encounter was individually necessary, and that can lead to denied claims and recoupment of payments. Each note must stand on its own as a specific account of a specific visit, which is why a freshly written, focused note is safer than a carried-forward one.
Where does the physical exam go, in the H&P and in the SOAP note?
In both documents, the physical examination is based on objective data. In the H&P, it appears as the complete physical examination section; in the SOAP note, it belongs in the Objective section as the focused exam for that encounter. It does not belong in the Assessment. The Assessment is the diagnostic synthesis, your working diagnosis and reasoning, not a restatement of exam findings, and confusing the two is one of the most common documentation errors NP students make.

Getting the Document to Match the Encounter
The distinction is simple to state and easy to apply once the principle is in view: the H&P is the comprehensive foundation you lay once, the SOAP note is the focused update you write at every visit after, and the encounter itself tells you which one it needs. The stakes are real because the current E/M rules reward clear clinical reasoning over documented volume, and because a note that leans on copied text rather than fresh reasoning can fail on medical necessity. Write the document the encounter calls for, keep the assessment a genuine diagnostic synthesis, and let each note stand on its own.
