Medical Chronology

A clear, dated timeline of one patient's care after a collision, pulled together from 847 pages across five providers into a single record you can read at a glance. Every entry cites the page it came from. We organize the facts; we don't draw legal conclusions, weigh in on causation, or track deadlines.

Patient: Sample, J. (DOB 01/14/1990) Date of incident: rear-end collision, 03/02/2026 Records reviewed: 847 pages from 5 providers Also in this example: a gap list and a billing documentation check

02 Treatment summary

The patient was rear-ended on 03/02/2026 and went to the Metro General ER the same day with neck and low-back pain. A head CT and a lumbar X-ray both came back clear of any acute injury, and the ER chart recorded "cervical strain; lumbar strain" (pp. 1–58). Three days later, a primary-care visit on 03/05/2026 noted low-back pain spreading down into the left leg, written up as "lumbago with left-sided sciatica," and set up referrals to orthopedics and physical therapy (pp. 59–71). Orthopedics saw the patient on 03/14/2026, found exam signs pointing to an irritated nerve in the lower back, and ordered an MRI (pp. 93–116).

The MRI on 03/28/2026 confirmed a disc problem at the L4–L5 level, reported as an "L4–L5 disc protrusion with left neural foraminal narrowing" (pp. 169–198). The patient started physical therapy on 04/10/2026 and finished 24 visits by 06/05/2026, with pain easing from 7/10 down to 4/10 (pp. 215–560). When the leg pain kept up despite therapy, orthopedics gave a steroid injection at the L4–L5 level on 05/06/2026 (pp. 117–168). At the last visit in this set, on 06/12/2026, the patient reported about 50% relief with some on-and-off left-leg pain still remaining (pp. 72–92).

03 Gap list

A gap is a period of more than 30 days with no treatment record in this set. Each one is listed with its dates, its length, and the page cited on either side. We flag gaps in the records, with citations, so the attorney can decide what they mean.

PeriodLengthBefore the gapAfter the gap

Over 14 monthsA 2024 lumbar X-ray at an outside facility, mentioned in the ER note (p. 41). The X-ray itself is not in this set.Metro General ER visit, 03/02/2026 (pp. 1–58)

After the collision, no period between treatment dates is longer than 30 days. The last treatment record in this set is dated 06/12/2026 (pp. 72–92); the set holds none after it.

04 Flags: items to verify

  • Last record in the set. The most recent treatment record is the 06/12/2026 primary-care visit (pp. 72–92), and the set holds no treatment record dated after it. We can request later records if you ask.
  • Mentioned but not included. The 04/22/2026 orthopedic note raises a possible surgical consult "if symptoms recur" (p. 138), but no spine-surgery records are in this set.
  • Earlier history noted. The primary-care intake notes "occasional low-back pain prior to the collision, no treatment" (p. 62). We flag it exactly as written and leave any call on its relevance to counsel.
  • Older imaging referenced. The ER note mentions a 2024 lumbar X-ray "at an outside facility" (p. 41) that isn't in this set; we can request it if it matters.
  • Unreadable entry. A provider signature and one line of vitals on a therapy note can't be read [ILLEGIBLE: p. 388].
  • Billing to itemize. The physical-therapy visit notes (pp. 243–560) show visit totals, but several dates are missing line-item billing codes; we've requested a fully itemized ledger (p. 601). The billing documentation check in section 05 matches each charge to the record for its date of service.

05 Billing documentation check

We check that every billed code is supported by the record for that date of service. Each charge is matched to the visit, procedure or report dated that day, with the page it comes from, and shown with the codes the provider billed. Supported means the record for that date documents the service billed. Flagged means it does not, or it documents something different; the reason is in the Record column, for the attorney to review.
