What nurses actually do
Nursing is the clinical backbone of most care settings — nurses assess patients, carry out the plan of care, administer treatments and medications, monitor for changes, educate patients and families, and coordinate with the rest of the care team. Their documentation also happens to be some of the richest source material a coder will ever read.
The nursing credential ladder
| Credential | Typical path | Scope |
|---|---|---|
| CNA | Short certificate program | Basic patient care under supervision (hygiene, vitals, mobility) |
| LPN / LVN | ~1 year practical nursing program | Basic clinical care under an RN or physician |
| RN | Associate (ADN) or Bachelor's (BSN) degree + licensing exam (NCLEX-RN) | Full scope of nursing care, assessment, and care planning |
| APRN | Master's or doctoral degree beyond RN | Nurse Practitioner, Certified Nurse Midwife, Clinical Nurse Specialist, or Nurse Anesthetist — can diagnose and prescribe depending on state law |
The Nursing Process (ADPIE)
Nurses are trained to work through patient care using a structured, repeatable framework:
The Nursing Process (ADPIE) repeats for every patient problem — Evaluation often loops back into a new Assessment.
- Assessment — collect data: vitals, symptoms, history, observations
- Diagnosis — identify the patient's problem (a nursing diagnosis, distinct from a physician's medical diagnosis)
- Planning — set measurable goals and choose interventions
- Implementation — carry out the plan: treatments, education, medications
- Evaluation — check whether the goal was met, and adjust
Where nurses work
Hospitals (inpatient units, ED, ICU), physician offices, outpatient surgery centers, skilled nursing and long-term care facilities, home health, hospice, schools, and telehealth — nursing roles exist in nearly every setting on the continuum of care.
Why nursing documentation matters to coders and billers
Nurses often document details that directly support code assignment, even though they aren't the ones assigning the code:
- Present on Admission (POA) indicators often rely on nursing assessment notes from admission
- Wound staging and skin assessments support pressure ulcer and wound care coding
- Fall risk, nutrition, and pain assessments can support medical necessity for services billed
- Time-based interventions (e.g., critical care time, infusion start/stop times) frequently come from the nursing flowsheet, not the physician note
Note: scope of practice for LPNs, RNs, and APRNs varies by state — what one state allows an APRN to do independently, another may require physician oversight for. This matters when you're coding services and checking who's licensed to perform or bill for them.
If you're coming from a nursing background into coding
Clinical experience is a genuine advantage for a future coder or auditor — you already understand disease processes, treatment sequences, and clinical documentation norms. What's new is translating that knowledge into the specific rules of ICD-10-CM, CPT, and payer policy, which the certification-specific guides in this library walk through.
