How Vet Records Are Structured (SOAP Notes)
The vast majority of veterinary visit documentation follows the SOAP format: Subjective, Objective, Assessment, Plan. This is the same format used in human medicine. Understanding each section tells you exactly what type of information lives where - and which sections carry the most risk for insurance purposes.
S - Subjective: What the owner reported. This is your own words, filtered through the vet's notes. “Owner reports occasional limping after long walks.” “Owner noticed dog scratching left ear.” “Owner states dog has been drinking more water than usual.” This section is particularly important because it documents symptoms you described - not necessarily anything the vet observed or confirmed. That distinction doesn't protect you with an adjuster: reported symptoms are documented symptoms.
O - Objective: What the vet found on physical examination. Vital signs, palpation findings, auscultation (heart and lung sounds), range of motion tests, skin and coat observations, lymph node assessment, dental grade. “Mild crepitus noted in left hip on range of motion testing.” “Grade 2 heart murmur auscultated.” “Skin: mild seborrhea noted bilaterally.” This section carries the most weight because it reflects the vet's clinical findings, not just owner reports.
A - Assessment: The vet's conclusions. This may be a formal diagnosis (“otitis externa, bacterial”), a working diagnosis (“suspected food allergy”), a rule-out list (“R/O hypothyroidism, R/O Cushing's”), or a monitoring note (“murmur - monitoring for progression”). Any of these can trigger a pre-existing exclusion, including the rule-outs that never resulted in a confirmed diagnosis. P - Plan: Treatment prescribed, follow-up recommended, referrals made, monitoring instructions. “Recheck in 6 months,” “renal panel in 3 months,” and “orthopedic consult recommended” are all entries that signal ongoing concern about a condition - and adjusters read them that way.
