About this data

Place of Service is the two-digit code in box 24B of the CMS-1500 that tells the payer where a service happened.

It is small but consequential. POS drives facility versus non-facility reimbursement, so the wrong code is a denial or an underpayment rather than a cosmetic error.

CMS updates the set rarely, every few years, and lists many two-digit numbers as unassigned. We publish only the assigned codes. A page for each unassigned number would say nothing.

We do not display CPT codes. Level I is owned by the American Medical Association and requires a paid license. Everything on this site is public domain or free to use.

How place of service codes work

The place of service code goes in box 24B of the CMS-1500 and answers one question: where was the patient when the service happened.

Not where the provider was. Not where the practice is. The patient.

It decides what you get paid

Place of service drives facility versus non-facility pricing. The same procedure pays differently depending on which code is on the claim.

The logic is that when a patient is at home or in your office, you carry the full overhead of delivering the service. When they are in another facility, that facility carries part of it, so the professional payment is lower.

Which makes the place of service a factual statement with financial consequences, and one that is trivially easy for a payer to audit against their own records.

The settings that come up most

Ninety nine two-digit numbers exist. Most practices use fewer than ten.

Office and outpatient

The everyday settings for ambulatory care.

11 19 22 49 71 72

Telehealth

Split by where the patient was, which changed in 2022 when CMS added a dedicated code for the patient at home.

02 10

Inpatient and facility

Hospital and institutional settings.

21 23 24 31 32 51 61

Home and residential

Where the patient lives, which covers more settings than people expect.

12 13 14 16 33

Behavioral health and substance use

Dedicated codes for treatment settings.

52 53 55 56 57 58

The ones that cause the most confusion

11 Office.

Your own practice location. Not a telehealth code, despite some commercial payers asking for it on telehealth claims with a CPT modifier.

10 Telehealth provided in the patient's home.

The patient was at their residence. Pays at the non-facility rate, which is usually higher.

02 Telehealth provided anywhere other than the patient's home.

The patient was at work, in a facility, or anywhere that is not a residence. Pays at the facility rate.

22 On campus outpatient hospital.

Hospital outpatient departments on the main campus. Distinct from 19, which is off campus.

31 Skilled nursing facility.

Often confused with 32. The distinction turns on whether the patient is in a covered Part A stay.

Common errors

Using the provider location

The single most frequent error. The code describes where the patient was.

Defaulting everything to one code

If your telehealth distribution is entirely one code, nobody is asking where the patient actually was. That is easy to audit.

Not documenting the location

If the claim says the patient was at home, the note should support it. That one line is what protects the claim in review.

What is not listed here

CMS lists a number of two-digit values as unassigned. Those carry no meaning and are not published here, because a page for each would say nothing.

Only the assigned codes appear, imported directly from the CMS code set.

Reference information only. Not billing advice. Verify against the payer before you file.
