410-129-0280 Hearing Testing for Diagnostic Purposes on Physician’s Referral Only (1) A physician's referral is required for the tests shown in this rule. The tests may only be performed and billed by a licensed audiologist or a licensed physician. (2) Procedure codes are the following: (a) 92541 – Spontaneous nystagmus test, including gaze and fixation nystagmus, with recording; (b) 92542 – Positional nystagmus test, minimum of four positions, with recording; (c) 92543 – Caloric vestibular test, each irrigation (binaural, bithermal stimulation constitutes four tests) with recording; (d) 92544 – Optokinetic nystagmus test, bidirectional, foveal or peripheral stimulation, with recording; (e) 92545 – Oscillating tracking test, with recording; (f) 92546 – Sinusoidal vertical axis rotational testing; (g) 92547 – Use of vertical electrodes in any or all the above tests counts as one additional test; (h) 92548 – Test for balance and posture; (i) 92551 – Screening test, pure tone, air only; (j) 92552 – Pure tone audiometry (threshold); air only; (k) 92555 – Speech audiometry; threshold only; (L) 92556 – With speech recognition; (m) 92562 – Loudness balance test, alternate binaural or monaural; (n) 92563 – Tone decay test; (o) 92564 – Short increment sensitivity index (SISI); (p) 92565 – Stenger test, pure tone; (q) 92567 – Tympanometry; (r) 92568 – Acoustic reflex testing; threshold; (s) 92569 – Acoustic reflex testing; decay; (t) 92571 – Filtered speech tests; (u) 92572 – Staggered spondaic word test; (v) 92575 – Sensorineural acuity test, test to assess hearing loss using different tone pitches; (w) 92576 – Synthetic sentence identification test; (x) 92577 – Stenger test, speech; (y) 92579 – Visual reinforcement audiometry (VRA); (z) 92582 – Conditioning play audiometry; (aa) 92583 – Select picture audiometry; (bb) 92584 – Electocochleography, test to assess electrical potentials generated in the inner ear as a result of sound stimulation; (cc) 92585 – Auditory evoked potentials for evoked response audiometry or testing of the central nervous system, comprehensive; (dd) 92586 – Auditory evoked potentials for evoked response audiometry or testing of the central nervous system, limited; (ee) 92587 – Evoked Otacoustic Emissions, - limited (single stimulus level, either transient or distortion products); (ff) 92588 – Evoked Otacoustic Emissions, comprehensive or diagnostic evaluation (comparison of transient or distortion product otoacoustic emissions at multiple levels and frequencies); (gg) 92620 – Auditory function 60 minutes, evaluation of hearing function brain responses, first hour (hh)92621 – Auditory function +15 minutes, evaluation of hearing function brain responses, each additional 15 min (ii) 92589 Central auditory function tests (specify).
