Phyathai 1 Hospital is the founding hospital of the Phyathai Hospitals Group, opened on 30 July 1976 on Si Ayutthaya Road in Bangkok's Ratchathewi district. The group has since grown to six hospitals across greater Bangkok and Sriracha (Phyathai 1, 2 and 3, plus Phyathai Phaholyothin, Phyathai Nawamin and Phyathai Sriracha). Phyathai 1 itself spans three buildings with 220 beds, and the hospital reports receiving around 1,500 patients a day, averaging roughly 40,000 patients a month. BAANLYY is not affiliated with Phyathai and takes no paid placement in this guide; all figures below should be confirmed directly with the hospital before relying on them.
Phyathai 1 is best known for neurosurgery, and its own site highlights a specialist team built around:
The hospital operates numerous additional medical centres beyond neurosurgery; see its own Centers page for the current full list, since BAANLYY does not itemise departments it cannot independently verify.
Across the Phyathai Hospitals Group, including Phyathai 1, the group provides services aimed at international patients and tourists such as interpreter support, international-ward facilities, and free medical consultation and advice by phone or online. Branch-specific details (languages covered, dedicated international-patient desk hours) are best confirmed directly with Phyathai 1 before you arrive, since BAANLYY has not independently verified branch-level specifics beyond what the hospital and group publish.
The hospital sits on Si Ayutthaya Road in Ratchathewi district, described by independent sources as "not far from" Ratchaprarop Station on the Airport Rail Link. BTS Phaya Thai (an interchange with the Airport Rail Link) and BTS Victory Monument are both within easy taxi or motorcycle-taxi reach; walking-distance estimates vary between sources, so it's sensible to allow a few extra minutes or take a short ride from whichever of the three stations you're arriving from.

Phyathai 1's own JCI (Joint Commission International) accreditation status is not independently confirmed. Don't confuse it with its sister hospital Phyathai 2 (Phahon Yothin Road, near Sanam Pao BTS), which received JCI accreditation in 2014 -- that accreditation applies to the Phyathai 2 branch, not automatically to the wider group. Confirm Phyathai 1's current accreditation status directly with the hospital or via the JCI accredited-organizations directory before relying on it.
Phyathai 1 sits on Si Ayutthaya Road in Ratchathewi district, not far from Ratchaprarop Station on the Airport Rail Link. BTS Phaya Thai (which also connects to the Airport Rail Link) and BTS Victory Monument are both a short taxi or motorcycle-taxi ride away; sources differ on exact walking distance from each station, so allow extra time or take a quick cab/moto ride rather than assuming a short walk.
Phyathai 1 is the founding hospital of the Phyathai Hospitals Group, opened in July 1976, and is particularly known for neurosurgery -- including minimally invasive spinal cord and spine surgery, laser spine surgery, and endoscopic treatment for acute stroke and related conditions. It also operates as a general multi-specialty hospital across its three buildings; see the hospital's own Centers page for the current full specialty list.
Phaya Thai and Victory Monument are the closest condo-heavy neighbourhoods, both served by BTS (and Phaya Thai also by the Airport Rail Link). See each area's full guide for transport, schools and condo pricing.
Hospital facts are drawn from Phyathai's own official website plus an independent cross-check; JCI accreditation is stated only where confirmed for this specific branch. BAANLYY is a data-and-tools platform, not a hospital, insurer or booking agent; never takes paid placement in this content, and does not guarantee prices, wait times or accreditation status — always confirm directly with the hospital before relying on any figure here.
