ADMIN-01 · CPT Coding, Billing, and Documentation

CPT Coding, Billing, and Documentation. Topics: E/M Codes, Modifiers, the 8-Minute Rule, and IRF Requirements. Part of the Administration & Practice series of the Reflex PM&R Board Review podcast. Audio corrections: (1) In the audio: has a primary diagnosis drawn from a specific federal mandated list of 13 qualifying conditions set by CMS. — Correct: The qualifying condition need not be the admitting diagnosis. A listed comorbidity can count when it causes functional decline requiring IRF-level treatment even without the admitting condition, and that treatment cannot appropriately be performed in another covered setting (42 CFR 412.29(b)). A generic diagnosis-code match alone does not establish this clinical qualification. (2) In the audio: They are stroke, spinal cord injury, congenital deformity, amputation, major multiple trauma, hip fracture brain injury, a specific group of neurological disorders, — Correct: The recited list ends without severe or advanced osteoarthritis of two or more major weight-bearing joints, which is its own category, and it counts the inflammatory arthritides as three. Rheumatoid, psoriatic and seronegative arthropathies together are ONE category; systemic vasculitides with joint inflammation are a second; severe or advanced osteoarthritis of two or more major weight-bearing joints is a third. (3) In the audio: at discharge, and at interim points if a stay runs unusually long past 60 days. — Correct: IRF-PAI assessments occur at admission and discharge, without a generic interim or 60-day reassessment (42 CFR 412.610). A qualifying interrupted stay returns to the same IRF by midnight of the third consecutive calendar day, counting discharge as day 1; the original admission assessment and case-mix classification persist (42 CFR 412.602 and 412.618). (4) In the audio: Level five is supervision or setup. The patient does at least 75% of the physical work, — Correct: Level 5 is defined by the absence of physical contact, not by a percentage. The at-least-75-percent threshold belongs to level 4 (minimal contact assistance); at level 5 the patient performs the task and the helper only stands by to cue, prompt, or set up. (5) In the audio: In 2019, the federal government transitioned the IRFPAI to use standardized GG codes for self-care and mobility items. — Correct: Section GG reached the IRF-PAI on October 1, 2016 (version 1.4). 2019 is when the FIM was removed from the instrument (October 1, 2019, version 3.0); case-mix group assignment has used a GG-derived motor score since FY2020. (6) In the audio: from about 13,000 codes to roughly 70,000 codes. — Correct: 14,567 ICD-9-CM diagnosis codes (CMS version 32) and 69,823 ICD-10-CM diagnosis codes in the FY2016 release. (7) In the audio: requirement to maintain LTCH status is that their average length of stay must be 25 days or greater. — Correct: The classification test is an average Medicare inpatient length of stay of MORE THAN 25 days, so a facility averaging exactly 25.0 days does not qualify (42 CFR 412.23(e)(2)(i); Social Security Act sec. 1886(d)(1)(B)(iv)(I)). The average is also narrower than the whole census: it is Medicare inpatient days divided by Medicare discharges, and for cost reporting periods beginning on or after October 1, 2015 it excludes discharges paid at the site-neutral rate and those paid by Medicare Advantage.
