## History and physical: what each part means and how to test it against the chart

For attorneys, legal nurse consultants, claims reviewers, underwriters and clinicians. You get the parts of an H&P, the federal timing rules for admissions and surgery, the update note, what research shows about templated and copied documentation, a worked pre-operative example, an H&P template and a review log.

By [Ahmed Jemaa](https://medrecords.ai/authors/ahmed-jemaa/), Co-Founder and CEO, Medrecords AI. Published 26 September 2026.

A history and physical, or H&P, is the clinician's first full assessment of a patient: the complaint, the history of the illness, past history, medications and allergies, a review of systems, the physical examination and an assessment with a plan. Federal hospital rules require one within 30 days before or 24 hours after admission, and before surgery.

The history and physical is where the chart starts. Every later note builds on it: the medication list, the allergies, the baseline exam, the working diagnosis. When it is wrong, the error travels forward. And because it is long and partly templated, it is also the note most likely to say more than was actually asked or examined.

This guide is built from the Medicare hospital Conditions of Participation for medical staff, medical records and surgical services (42 CFR 482.22, 482.24 and 482.51), the CMS State Operations Manual interpretive guidance, an observational study of emergency physician documentation (JAMA Network Open, 2019), a study of where progress note text comes from (JAMA Internal Medicine, 2017), a systematic review of medication history errors at admission (CMAJ, 2005) and a review of copy-and-paste practices (Chest, 2014). The worked example is hypothetical. Nothing here is legal or medical advice.

### What a history and physical is

A history and physical, usually shortened to H&P, is the complete first assessment of a patient by a physician or another qualified clinician. It is written on admission to hospital, before surgery, and at the start of care in many other settings. CMS describes its purpose as finding anything in the patient's condition that would affect the planned treatment, such as a medication allergy or a condition that needs extra precautions.

The H&P has 2 halves. The history is what the patient, family or old records report: symptoms, past illnesses, medications, allergies, family and social history. The physical is what the clinician examined. The assessment and plan pull them together into a working diagnosis and next steps.

For a reviewer, the H&P sets the baseline. It is the first place to look for what was known at admission, and the document later notes tend to copy from. It is also a document where templates and copied text are common, so each statement in it deserves the question: was this asked, examined and found, or was it filled in?

#### Terms you will meet

Chief complaint (CC)The reason for the visit, often in the patient's words.
History of present illness (HPI)The story of the current problem: onset, course, severity, what makes it better or worse.
PMH, PSHPast medical and past surgical history.
Review of systems (ROS)A checklist of symptoms by body system. "14-point ROS negative" means 14 systems were reported as asked about and negative.
Physical exam (PE)Findings by system: vital signs, general appearance, heart, lungs, abdomen, neurologic and so on.
Assessment and plan (A/P)The clinician's diagnosis or differential and what will be done.
Update noteA short entry confirming or updating an H&P done before admission. Required within 24 hours and before surgery.
Pertinent negativeA symptom or finding specifically looked for and absent. It matters when the absence is later disputed.

If you remember one thing
The H&P is the baseline every later note copies from. Test each statement: was it asked, examined and found, or filled in?

### The parts of an H&P, section by section

The mock H&P below was written before a planned knee replacement. The layout is invented; every hospital's template differs. The 9 marked parts appear in almost every H&P.

History and physical Hypothetical
Patient H, 67. Pre-operative, right total knee
CC — Right knee pain, 3 years1
HPI — Worsening pain, failed injections and therapy2
PMH / PSH — Hypertension, type 2 diabetes. Appendectomy3
Meds / allergies — Lisinopril, metformin. NKDA4
FH / SH — Former smoker, 20 pack-years5
ROS — 14-point review negative except HPI6
Exam — Heart: regular rate and rhythm. Right knee effusion7
A/P — Right knee osteoarthritis. Cleared for surgery8
Signature — Dr. P, primary care, 05/20/2026 16:129
HYPOTHETICAL
1. 1
**Chief complaint** Why the patient is here. It should match the order, the consent and the procedure.
2. 2
**History of present illness** The most individual section, and usually the most useful. A short or generic HPI is a signal about the rest.
3. 3
**Past history** Illnesses and operations. Compare with the problem list and other providers' notes.
4. 4
**Medications and allergies** The list later orders are built from. Admission medication histories are wrong often enough that every list needs a second source.
5. 5
**Family and social history** Smoking, alcohol, living situation. Relevant to risk and to discharge.
6. 6
**Review of systems** Often a template. "14-point negative" should be tested against other notes from the same days.
7. 7
**Physical exam** Baseline findings. Templated normal exams can contradict findings documented by others.
8. 8
**Assessment and plan** The working diagnosis and, before surgery, whether the patient is fit to proceed.
9. 9
**Signature and time** Who wrote it and when. Date against the 30-day window and the time of surgery.

#### What to check each section against

| H&P section | Second source | What a reviewer checks |
| --- | --- | --- |
| Medications | Nursing admission medication reconciliation, pharmacy records, MAR | Drugs missing or added |
| Allergies | Nursing intake, pharmacy profile, prior records | Allergies recorded elsewhere but not here |
| Past history | Specialist notes, problem list, prior discharge summaries | Diagnoses known to others but absent |
| ROS | Nursing assessment, ED triage, patient questionnaire | Symptoms reported elsewhere on the same day |
| Physical exam | Nursing assessment, vital signs, other clinicians' exams | Normal findings contradicted by others |
| Date and time | Admission time, anesthesia record | Within 30 days; update before surgery |

If you remember one thing
Every section of the H&P has a second source. The medication list and the templated normal findings are where they disagree most.

Chapter 3 Deciding

### Templates, copied text and what the H&P really records

Electronic records made the H&P faster to write. Templates fill in a normal review of systems and a normal exam with 1 click; earlier notes can be copied forward; results and lists import automatically. A 2014 review in Chest describes the risks: unclear authorship, outdated information carried forward, and notes that no longer show what was actually done.

How much of a note is original? A UCSF study of inpatient progress notes found that in a typical note, 18% of the text was typed by the author, 46% was copied and 36% was imported. Progress notes are not H&Ps, but the same tools write both.

How much of a documented exam happened? Berdahl and colleagues sent trained observers into 180 emergency department encounters and compared what they saw and heard with what the residents documented:

**Systems documented vs confirmed in 180 ED encounters** — median per visit — Berdahl et al., 2019
Across all visits, 38.5% of documented review-of-systems items and 53.2% of documented exam systems were confirmed. The study covered 9 residents at 2 academic centers, so it is small, but the direction is clear.

None of this means a templated note is false. It means a line like "14-point ROS negative" or "heart: regular rate and rhythm" is weak evidence on its own. When a case depends on what was asked or found at admission, it should be tested against notes written independently on the same day, such as nursing assessments, triage notes and specialist notes.

If you remember one thing
A templated normal finding is weak evidence alone. Test it against independent notes from the same day.

Chapter 4 Everyone

### The rules behind the H&P

The federal hospital rules set when an H&P must be done, who may do it and when an update is required. The same timing appears in 3 places: the medical staff bylaws rule, the medical records rule and the surgical services rule.

| Rule | What it requires | What it means for review |
| --- | --- | --- |
| 42 CFR 482.22(c)(5)(i) | H&P no more than 30 days before or 24 hours after admission or registration, but before surgery or a procedure requiring anesthesia, by a physician or other qualified licensed individual | Check the date against both limits and the author's credentials |
| 42 CFR 482.22(c)(5)(ii) | If the H&P was done within 30 days before admission, an updated examination including any changes, within 24 hours after admission and before surgery | Look for the update note and its time |
| 42 CFR 482.24(c)(4)(i) | The H&P and the update must be placed in the record within 24 hours after admission, before surgery | Filed time as well as written time |
| 42 CFR 482.51(b)(1) | Before surgery or anesthesia, except emergencies, the H&P and update must be completed and documented | Compare with the anesthesia start time |
| 42 CFR 482.24(c)(1) | Every entry legible, complete, dated, timed and authenticated | Check author and times |

[](https://www.law.cornell.edu/cfr/text/42/482.22) [](https://www.law.cornell.edu/cfr/text/42/482.22) [](https://www.law.cornell.edu/cfr/text/42/482.24) [](https://www.law.cornell.edu/cfr/text/42/482.51) [](https://www.law.cornell.edu/cfr/text/42/482.24)
CMS guidance adds 3 points that matter in review. An H&P can be split among several practitioners, and the one who authenticates it is responsible for its contents. A pre-admission H&P can come from the patient's own doctor, which is how outside documents enter the hospital chart. And timing is judged against the procedure:

"An H&P that is completed within 24 hours of the patient's admission or registration, but after the surgical procedure, procedure requiring anesthesia, or other procedure requiring an H&P would not be in compliance with this requirement."

#### The update note

When the H&P was done before admission, the update note is the hospital's own check. CMS says the update must document an examination for any changes that might matter for the planned treatment. If there are none, the practitioner may record that the H&P was reviewed, the patient examined and "no change" found. A "no change" update written when other notes show a change is a common finding. Our guides to [altered medical records](https://medrecords.ai/guides/altered-medical-records/) and [EHR audit trails](https://medrecords.ai/guides/ehr-audit-trail-medical-malpractice/) cover how to test when an update was actually written.

If you remember one thing
Put the H&P date, the update time and the anesthesia start time side by side. The update has to come before the procedure.

Chapter 5 Deciding

### The medication history and other patterns

The medication list in the H&P is what admission orders are built from, and it is wrong often. Tam and colleagues reviewed 22 studies with 3,755 patients comparing physicians' admission medication histories with comprehensive ones. Errors occurred in up to 67% of cases: 10% to 61% of patients had at least 1 drug left off, and 13% to 22% had a drug added that they were not taking. In the studies that judged severity, 11% to 59% of the errors were clinically important.

That is why nursing and pharmacy medication reconciliation exists, and why the reconciliation and the H&P should be read together. When they disagree, the question is which list the orders followed.

| Pattern | Example | Why it is a question |
| --- | --- | --- |
| Medication missing | Anticoagulant on the nursing reconciliation, not in the H&P | Was it held, continued or overlooked? |
| Outdated H&P | H&P dated 36 days before surgery | Outside the 30-day window |
| "No change" update against a changed chart | New diagnosis in a specialist note after the H&P | Was the patient re-examined? |
| Update after the procedure | Update signed after anesthesia start | Not compliant with the timing rule |
| Templated normal exam contradicted | "Regular rhythm" while ECG shows atrial fibrillation | Was the exam done as documented? |
| Copied H&P | Identical text to a prior admission's H&P, including old vitals | What was current at this admission? |
| Allergy mismatch | "NKDA" in the H&P; penicillin allergy on the pharmacy profile | Which list reached the orders? |

For the drugs actually given, the [medication administration record guide](https://medrecords.ai/guides/medication-administration-record/) shows how to line up orders, the MAR and the H&P. For daily notes that copy from the H&P, see the [SOAP note guide](https://medrecords.ai/guides/soap-note/).

If you remember one thing
Read the H&P medication list beside the nursing reconciliation. When they differ, find which one the orders followed.

### Worked example: a pre-op H&P that missed a new blood thinner

**Hypothetical.** The patient, physicians, hospital, dates and pages are invented to show the method. It is not a real case or a customer file. Patient H, 67, has a right knee replacement on 06/15/2026. The pre-admission H&P was written by the primary care doctor on 05/20. On 05/28 a cardiologist diagnosed atrial fibrillation and started an anticoagulant. On the night after surgery the knee swells, and on 06/16 the patient returns to the operating room for a hematoma. The file holds the H&P and update (pages 4 to 7), the cardiology note (page 12), pre-op labs (page 15), nursing admission (page 20), the anesthesia record (page 24), nursing notes (page 30) and the return-to-OR report (page 34).

**The H&P beside the other records from the same weeks** — hypothetical — Illustration
H&P review log, 05/20 to 06/16/2026, hypothetical — 9 entries
| Date | Source | Record says | Question | Page |
| --- | --- | --- | --- | --- |
| 05/20 16:12 | H&P (PCP) | Meds: lisinopril, metformin. ROS 14-point negative. Heart regular | Baseline; the list the orders will copy | 4 to 6 |
| 05/28 | Cardiology note | New atrial fibrillation; anticoagulant started | After the H&P was written | 12 |
| 06/10 | Pre-op labs | Within normal limits | No coagulation-specific result for the new drug | 15 |
| 06/15 06:20 | Nursing admission | Home meds include anticoagulant, last dose 06/14 20:00 | Recorded before surgery | 20 |
| 06/15 07:15 | Pre-op nursing | Irregular pulse 96 | Contradicts "regular" in the H&P | 21 |
| 06/15 07:30 | Anesthesia record | Anesthesia start | The time the update had to precede | 24 |
| 06/15 09:40 | H&P update | "H&P reviewed, patient examined, no change" | Signed after anesthesia start; no mention of AF or the drug | 7 |
| 06/15 22:10 | Nursing note | Dressing saturated, knee tense and swollen | Time to first physician response | 30 |
| 06/16 10:00 | Operative report | Return to OR, evacuation of hematoma | The event the timeline builds toward | 34 |

Gold rows: entries that need a question. Green row: the event the timeline builds toward.
9 entries, 5 questions. The H&P was accurate on the day it was written. By the day of surgery it was not, and the update note says nothing changed.

#### What each flag means

1. **A baseline that aged.** The 05/20 H&P was within the 30-day window, but a new diagnosis and a new drug came 8 days later. That is what the update note exists to catch.
2. **The drug was in the chart before surgery.** Nursing recorded the anticoagulant and its last dose at 06:20. Whether the surgical and anesthesia teams saw it is in their notes, orders and the audit trail.
3. **A contradicted exam.** The pre-op nurse recorded an irregular pulse 15 minutes before anesthesia. The H&P says regular rhythm; the update says no change.
4. **An update written after the procedure started.** Signed at 09:40, more than 2 hours after anesthesia start. Under CMS guidance, that timing does not comply. The audit trail shows whether it was written then or only signed then.
5. **The response to swelling.** The time from the 22:10 nursing note to the first physician note and the return to the operating room belongs on the timeline too.

#### The same case on 1 timeline

**Every dated entry that matters, H&P to return to the OR** — hypothetical — Illustration; pages refer to the hypothetical file

p. 34

Read in page order, the H&P comes first and looks complete. Read by date, it is 26 days old and the update came after the incision.

##### What the H&P record can show

When checked against the chart

- What was known and documented at each point.
- Whether the update came before the procedure.
- Which medication list the orders followed.
- Where templated findings conflict with other notes.

##### What it cannot show alone

Where you need another record or an expert

- Whether the drug should have been held, and for how long (an expert).
- Whether anyone asked the patient about new medications (testimony).
- When the update was actually written (audit trail).
- Whether the bleeding was caused by the drug (an expert).

If you remember one thing
An H&P can be right on the day it was written and wrong on the day of surgery. The update note is where that gap should close.

### How to review an H&P, step by step

The method works for an admission H&P, a pre-operative H&P or a clinic intake. Start with the dates, then test the content.

1. **Fix the times.** H&P date and signature, admission time, update time, anesthesia or procedure start.
2. **Check the window.** No more than 30 days before admission, and the update within 24 hours and before the procedure.
3. **Identify the authors.** Who performed, who documented, who authenticated. The authenticator is responsible.
4. **Compare the medication list.** Against nursing reconciliation, pharmacy records and the first orders.
5. **Compare the allergies.** Against nursing intake and the pharmacy profile.
6. **Test the templated findings.** ROS and exam against same-day nursing, triage and specialist notes.
7. **Look for copied text.** Identical wording or old values from a prior admission or visit.
8. **Look for what happened between.** Diagnoses, drugs and results between the H&P and the procedure, and whether the update mentions them.

#### Can this H&P be relied on as the baseline?

1
**Was it within 30 days, with an update before the procedure?**
YesGo to 2.
NoLog the dates. Look for any later H&P in the file.
2
**Do the medications and allergies match the nursing and pharmacy lists?**
YesGo to 3.
NoLog each difference and which list the orders followed.
3
**Do the ROS and exam agree with same-day independent notes?**
YesGo to 4.
NoLog each contradiction with both pages.
4
**Does the update reflect everything that changed since the H&P?**
YesRely on it as the baseline, cited to its page.
NoLog each change the update omits.

Fix the times first, then test the content. The H&P is only as good as its match with the records around it.

### AI and H&P review

Chapter 7's method compares the H&P with every other note from the same days: nursing reconciliation, triage, specialist notes, the anesthesia record. In a surgical file that is hundreds of pages, and the contradicting line is often in a note nobody thought to read.

AI medical record review can pull every medication, allergy, diagnosis and exam finding from every note onto an AI medical chronology, each with a page-level citation, and show the H&P's version beside the others. An anticoagulant on the nursing list and absent from the H&P, or an irregular pulse 15 minutes before a "no change" update, becomes visible without reading every page in order.

The same caution applies as with any large language model (LLM). A model summarizing a chart will lean on the H&P because it is complete and well organized, and can repeat its templated normals as fact. Hallucination and omission are both risks, which is why every line needs its page and a human in the loop checks it. Whether a drug should have been held is a clinical judgment.

Medrecords AI works this way on the files you upload. It builds a [cited medical chronology](https://medrecords.ai/product/chronology/) across the H&P, nursing, specialist and anesthesia records, each entry linked to its page. You can ask "every anticoagulant mentioned anywhere in the file, with dates and last-dose times" through [cited Q&A](https://medrecords.ai/product/qa/), find conflicting findings with [record search](https://medrecords.ai/product/medical-record-search/), surface statements of absence with [negative findings detection](https://medrecords.ai/product/negative-findings-detection/), and flag [records that should exist but were not produced](https://medrecords.ai/product/missing-records-identification/). Flags are signals, not verdicts. It does not decide whether care met the standard, parse audit trails or retrieve records from providers. It runs under SOC 2 and HIPAA with a signed business associate agreement (see [security](https://medrecords.ai/security/) and [HIPAA](https://medrecords.ai/hipaa/) ).

### Frequently asked questions

What is included in a history and physical?Chief complaint, history of present illness, past medical and surgical history, medications and allergies, family and social history, review of systems, physical examination, results reviewed, and an assessment and plan, signed with date and time.
How long is an H&P valid before surgery?Under federal hospital rules, an H&P done up to 30 days before admission can be used if an update note is completed within 24 hours after admission and before the surgery or procedure.
What is an H&P update note?A short entry confirming the patient was re-examined and recording any changes since a pre-admission H&P. If nothing changed, CMS allows the practitioner to record that the H&P was reviewed, the patient examined and no change found.
Who can perform a history and physical?A physician, an oral and maxillofacial surgeon, or another qualified licensed individual such as a nurse practitioner or physician assistant, as allowed by state law and hospital policy.
What does "14-point review of systems negative" mean?That 14 body systems are recorded as asked about and negative. It is often generated by a template, so it should be tested against other notes from the same day.
Can copied text in an H&P be a problem in a lawsuit?It can raise questions about what was actually current at the time. Identical wording or old values from an earlier visit are worth logging and comparing with independent notes.
What if the H&P was written after surgery?CMS guidance says an H&P completed after the procedure does not meet the requirement, even if it is within 24 hours of admission. Emergencies are an exception.
Can AI compare an H&P with the rest of the chart?It can extract medications, allergies and findings from every note and line them up with page citations so differences stand out. A clinician or expert decides what the differences mean.
Is it HIPAA compliant to upload hospital records to an AI tool?It can be, with a vendor that signs a business associate agreement, holds a SOC 2 report and commits in writing not to train on your data. A consumer chatbot without a BAA is a different matter.
