Yes. 보험증 refers to a document or card that proves your insurance coverage. In everyday situations like hospitals or clinics, it is often understood as your insurance card or proof of insurance.

• 보험 = insurance
• 증 = certificate / proof

So 보험증 is literally something like insurance certificate/proof, but in natural English, insurance card is often the best translation.

The 을 is the object marker. It marks 보험증 as the thing being brought.

So:

• 보험증을 가져오다 = to bring the insurance card

In this sentence, the action is 가져오다 (to bring), and the thing you bring is 보험증, so it gets 을.

Both are correct. They both mean if you do not bring it.

• 안 가져오면 = if you don’t bring it
• 가져오지 않으면 = if you do not bring it

The version with 안 is usually more conversational and shorter.
The -지 않다 version can sound a bit more formal or written.

So in everyday speech, 안 가져오면 is very natural.

-면 means if or when in a conditional sense.

• 가져오다 = to bring
• 가져오면 = if/when you bring
• 안 가져오면 = if you do not bring

So the first part of the sentence sets up a condition:

• 보험증을 안 가져오면 = If you don’t bring your insurance card

In Korean, medical treatment or medical attention is often expressed as 진료를 받다, literally to receive treatment/medical care.

• 진료 = medical treatment, consultation, care
• 받다 = to receive

So:

• 진료를 받다 = to receive medical treatment / to see the doctor

This is a very common Korean pattern. Korean often expresses these ideas as receiving a service:

• 치료를 받다 = receive treatment
• 교육을 받다 = receive education
• 도움을 받다 = receive help

This is 받다 + -기 전에, which means before receiving or before you receive.

Breakdown:

• 받다 = to receive
• 받기 = receiving / the act of receiving
  
  • here, -기 turns the verb into a noun-like form
• 전에 = before

So:

• 진료를 받기 전에 = before receiving treatment / before seeing the doctor

This is a very common grammar pattern:

• 먹기 전에 = before eating
• 가기 전에 = before going
• 자기 전에 = before sleeping

접수 means registration, check-in, or reception processing at a hospital or clinic.

부터 means from, starting from, or beginning with.

So 접수부터 means:

• starting from registration
• from the check-in stage onward
• even the registration part first

In this sentence, 부터 gives the nuance that the delay may begin as early as the registration step, even before treatment starts.

So the sentence is not just saying the whole process may take a long time. It specifically highlights that the registration/check-in stage itself can already take a long time.

It means it may take a long time.

Breakdown:

• 오래 = for a long time
• 걸리다 = to take time
• -ㄹ 수 있다 / -을 수 있다 = can / may / be possible
• 있어요 = polite present ending

So:

• 오래 걸리다 = to take a long time
• 오래 걸릴 수 있어요 = it may take a long time / it can take a long time

The 수 있어요 part softens the statement a bit. It does not mean it will always happen, but that it is a possibility.

The subject is omitted, which is very normal in Korean.

From context, what may take a long time is something like:

• the registration process
• the whole procedure before treatment
• the check-in process at the clinic

Korean often leaves this kind of subject unstated when it is obvious from context. In English, we usually supply something like it:

• It may take a long time

But in Korean, the sentence can sound completely natural without explicitly saying what it is.

Korean word order is flexible, but this order is natural because it builds the situation step by step:

1. 보험증을 안 가져오면 = if you don’t bring your insurance card
2. 진료를 받기 전에 = before receiving treatment
3. 접수부터 = starting with registration
4. 오래 걸릴 수 있어요 = it may take a long time

The phrase 진료를 받기 전에 sets the time frame first: before treatment.
Then 접수부터 zooms in on where the delay begins: starting at registration.

A natural interpretation is:

• If you don’t bring your insurance card, even before you receive treatment, starting from the registration process, things may take a long time.

It can mean several closely related things depending on the setting.

At a hospital or clinic, 접수 often refers to:

• checking in at the front desk
• submitting your information
• registering for your appointment
• reception processing

So in this sentence, 접수 is best understood as check-in or registration at reception.

It is polite, everyday standard Korean.

The ending -어요 in 있어요 makes it polite but not overly formal. This is the kind of Korean you might hear from:

• hospital staff
• reception staff
• service workers
• someone explaining procedures politely

A more formal version might end in -습니다 style, such as 걸릴 수 있습니다.

A fairly literal breakdown would be:

• 보험증을 안 가져오면 = if you don’t bring your insurance card
• 진료를 받기 전에 = before receiving treatment
• 접수부터 = starting from registration
• 오래 걸릴 수 있어요 = it may take a long time

So a more literal translation would be:

If you don’t bring your insurance card, it may take a long time starting from the registration process before you receive treatment.

A more natural English version would be something like:

If you don’t bring your insurance card, the check-in process may take a long time before you can see the doctor.
