Active from the 1940s through the 1990s, he is regarded as one of the most influential composers of South Indian cinema, known for his command over classical and devotional idioms as well as accessible film melodies. He worked closely with lyricists such as Kannadasan and Veturi Sundararama Murthy, and frequently with the writing-direction team of Aluri Chakrapani and B. Nagi Reddy at Vijaya–Vauhini Studios.

Mahadevan was born into a Tamil Brahmin family in the temple town of Krishnankoil in southern Tamil Nadu. He received early training in Carnatic music, which would remain a defining influence on his compositions, particularly in his settings of devotional and classical-based songs. He moved to Madras (now Chennai) to pursue a career in film music.
Mahadevan entered the Tamil film industry in the 1940s, initially working as an assistant before composing independently. His first major break as music director came with the Tamil film Manthiri Kumari (1950), produced by Modern Theatres, after which he steadily established himself in Tamil cinema during the 1950s with films such as Mohini and Sarvadhikari.
Through the 1950s and 1960s, Mahadevan composed for several major productions starring M. G. Ramachandran, Sivaji Ganesan and Gemini Ganesan. Notable Tamil films include Aayirathil Oruvan (1965), Enga Veettu Pillai (1965), Anbe Vaa (1966), Thiruvilaiyadal (1965), Saraswathi Sabatham (1966), Kandhan Karunai (1967) and Thiruvarutchelvar (1967). His devotional and mythological scores, often based on Carnatic ragas, are considered landmarks in Tamil film music. The song "Paattum Naane" from Thiruvilaiyadal, picturised on Sivaji Ganesan, is widely cited among his finest compositions.
From the late 1960s, Mahadevan became a dominant force in Telugu cinema, frequently associated with films produced by B. Nagi Reddy's Vijaya Productions and directed by figures such as K. Viswanath and Bapu. His Telugu work includes Adavi Ramudu (1977), Vetagadu (1979), Sankarabharanam (1980), Saptapadi (1981), Subhalekha (1982), Saagara Sangamam (1983), Sruthilayalu (1987) and Swati Mutyam (1986). The score of Sankarabharanam, rooted in Carnatic classical music, is regarded as one of the most significant achievements in Indian film music and contributed to a revival of public interest in classical music in Andhra Pradesh.
Mahadevan worked closely with his long-time assistant and arranger Pugazhendi, who handled much of the orchestration. He composed extensively for playback singers including Ghantasala, P. Susheela, S. P. Balasubrahmanyam, S. Janaki, T. M. Soundararajan and P. B. Sreenivas. His association with lyricists Kannadasan in Tamil and Veturi Sundararama Murthy and Aatreya in Telugu produced many of his most enduring songs.
Mahadevan was noted for the seamless integration of Carnatic classical structures into popular film music. His scores for mythological and devotional films, and later for the classical-themed films of K. Viswanath, demonstrated a rare ability to make raga-based music commercially successful. He is credited with shaping the sound of Tamil and Telugu film music across a span of more than five decades, and influenced succeeding generations of South Indian composers.
K. V. Mahadevan died in Chennai on 21 June 2001 at the age of 83.
