Inpatient - Hospital care or Observation Care

Inpatient coding: refers to the process of assigning codes to medical procedures, diagnoses, and services provided to patients who are admitted to a hospital or other healthcare facility for an overnight stay or longer. Inpatient coding is primarily used for reimbursement purposes, as it helps healthcare providers accurately bill insurance companies and government payers for the services rendered.

Hospital or observation care are divided in

  1. Initial Hospital or observation care

  2. Subsequent Hospital or observation care

  3. Discharge from Hospital or observation care

Date: December 31, 2023

Morning - Admission: Mr. Sharma, a 65-year-old male, is admitted to the hospital with severe chest pain. The attending physician, Dr. Patel, evaluates him and suspects a heart condition. Dr. Patel documents an admission note detailing Mr. Sharma’s symptoms, medical history, and initial treatment plan. This admission note is then billed.

Evening - Progress Note: Dr. Patel visits Mr. Sharma again in the evening to assess his condition. He notes that Mr. Sharma’s chest pain has lessened due to the medication. Dr. Patel documents a progress note outlining the patient’s response to treatment and any changes made to the treatment plan. However, only the admission note from the morning is billed for this day.

Date: January 2, 2024 - Discharge: on January 2, 2024, Dr. Patel sees Mr. Sharma in the morning and makes a progress note. However, this progress note is not billed separately. Later in the evening, when Dr. Patel discharges Mr. Sharma, a discharge note is prepared and billed. So, for this day, only the discharge visit is coded and billed. This is in line with the usual practice where only the most significant visit (in this case, the discharge) is billed on any given day.

AI Modifier:

AI modifier is appended to H&P note done for admission purpose when the payor is Medicare.

The AI modifier is used to identify the principal physician of record during an inpatient admission. This modifier should only be used by the admitting or attending physician overseeing the patient’s care during a hospital or nursing facility admission.

This modifier can be appended with 99221 to 99223, 99304 to 99306, and critical care code when critical care was warranted at the time of admission.

  1. Admission notes: an Admission Note, also known as an H&P (History and Physical) note, is a crucial part of a patient’s medical record. It documents the patient’s status, including their history and physical examination findings, the reasons why the patient is being admitted for inpatient care to a hospital or other facility, and the initial instructions for that patient’s care.

    • MD or DO can perform the admission independently and get billed.

    • NPPs can not perform the admission independently, they need cosign from the MD/DO

  2. Subsequent Note (Progress Note): Progress notes are clinical notes made by healthcare professionals involved in a patient’s treatment and care. They contain clinical facts and medical reasoning about the care delivered to patients and the clinical events relevant to diagnosis and treatment. They are professional documents that communicate important information on a patient’s condition between multiple providers.

    • Progress note can be documented by NPP alone as well. No cosign from MD/DO are needed.

  3. Discharge Note: A discharge note, also known as a termination, note or discharge summary, is a written summary held in the client’s chart of what happened during the time the client was in your care. It is often the primary mode of communication between the hospital care team and aftercare providers. It includes reasons for termination, symptoms at the time of intake, initial reasons for seeking treatment, diagnosis, treatment goals, modalities and interventions used, progress made during treatment, and recommendations for future mental health care needs.

    • Discharge can be billed independently by MD/DO. NPPs needs cosign by MD/DO.
